-To modify `disk-usage-warning-percentage` and `disk-usage-critical-percentage` thresholds, specify the parameters when executing the `gfsh create disk-store` command.
-
-``` pre
-gfsh>create disk-store --name=serverOverflow --dir=c:\overflow_data#20480 \
---compaction-threshold=40 --auto-compact=false --allow-force-compaction=true \
---max-oplog-size=512 --queue-size=10000 --time-interval=15 --write-buffer-size=65536 \
---disk-usage-warning-percentage=80 --disk-usage-critical-percentage=98
-```
-
-By default, disk usage above 80% triggers a warning message. Disk usage above 99% generates an error and shuts down the member cache that accesses that disk store. To disable disk store monitoring, set the parameters to 0.
-
-To view the current threshold values set for an existing disk store, use the `gfsh                 describe` disk-store command:
-
-``` pre
-gfsh>describe disk-store --member=server1 --name=DiskStore1
-```
-
-You can also use the following `DiskStoreMXBean` method APIs to configure and obtain these thresholds programmatically.
-
--   `getDiskUsageCriticalPercentage`
--   `getDiskUsageWarningPercentage`
--   `setDiskUsageCriticalPercentage`
--   `setDiskUsageWarningPercentage`
-
-You can obtain statistics on disk space usage and the performance of disk space monitoring by accessing the following statistics:
-
--   `diskSpace`
--   `maximumSpace`
--   `volumeSize`
--   `volumeFreeSpace`
--   `volumeFreeSpaceChecks`
--   `volumeFreeSpaceTime`
-
-See [Disk Space Usage (DiskDirStatistics)](../../reference/statistics/statistics_list.html#section_6C2BECC63A83456190B029DEDB8F4BE3).

-You define your disk stores by using the `gfsh create disk-store` command or in `<disk-store>` subelements of your cache declaration in `cache.xml`. All disk stores are available for use by all of your regions and queues.
-
-These `<disk-store>` attributes and subelements have corresponding `gfsh create disk-store` command-line parameters as well as getter and setter methods in the `org.apache.geode.cache.DiskStoreFactory` and `org.apache.geode.cache.DiskStore` APIs.

-
-## <a id="disk_store_configuration_params__section_366001C72D674AF69B2CED91BFA73A9B" class="no-quick-link"></a>disk-dirs Element
-
-The `<disk-dirs>` element defines the host system directories to use for the disk store. It contains one or more single `<disk-dir>` elements with the following contents:
-
--   The directory specification, provided as the text of the `disk-dir` element.
--   An optional `dir-size` attribute specifying the maximum amount of space, in megabytes, to use for the disk store in the directory. By default, there is no limit. The space used is calculated as the combined sizes of all oplog files.
-
-You can specify any number of `disk-dir` subelements to the `disk-dirs` element. The data is spread evenly among the active disk files in the directories, keeping within any limits you set.
-
-Example:
-
-``` pre
-<disk-dirs>
-    <disk-dir>/host1/users/gf/memberA_DStore</disk-dir>
-    <disk-dir>/host2/users/gf/memberA_DStore</disk-dir> 
-    <disk-dir dir-size="20480">/host3/users/gf/memberA_DStore</disk-dir> 
-</disk-dirs>
-```
-
-**Note:**
-The directories must exist when the disk store is created or the system throws an exception. Geode does not create directories.
-
-Use different disk-dir specifications for different disk stores. You cannot use the same directory for the same named disk store in two different members.

-<a id="handling_missing_disk_stores__section_9345819FC27E41FB94F5E54979B7C506"></a>
-This section applies to disk stores that hold the latest copy of your data for at least one region.
-
-## <a id="handling_missing_disk_stores__section_9E8FBB7935F34239AD5E65A3E857EEAA" class="no-quick-link"></a>Show Missing Disk Stores
-
-Using `gfsh`, the `show missing-disk-stores` command lists all disk stores with most recent data that are being waited on by other members.
-
-For replicated regions, this command only lists missing members that are preventing other members from starting up. For partitioned regions, this command also lists any offline data stores, even when other data stores for the region are online, because their offline status may be causing `PartitionOfflineExceptions` in cache operations or preventing the system from satisfying redundancy.
-
-Example:
-
-``` pre
-gfsh>show missing-disk-stores
-          Disk Store ID              |   Host    |               Directory                                           
------------------------------------- | --------- | -------------------------------------
-60399215-532b-406f-b81f-9b5bd8d1b55a | excalibur | /usr/local/gemfire/deploy/disk_store1
-```
-
-**Note:**
-You need to be connected to JMX Manager in `gfsh` to run this command.
-
-**Note:**
-The disk store directories listed for missing disk stores may not be the directories you have currently configured for the member. The list is retrieved from the other running members—the ones who are reporting the missing member. They have information from the last time the missing disk store was online. If you move your files and change the member’s configuration, these directory locations will be stale.
-
-Disk stores usually go missing because their member fails to start. The member can fail to start for a number of reasons, including:
-
--   Disk store file corruption. You can check on this by validating the disk store.
--   Incorrect distributed system configuration for the member
--   Network partitioning
--   Drive failure
-
-## <a id="handling_missing_disk_stores__section_FDF161F935054AB190D9DB0D7930CEAA" class="no-quick-link"></a>Revoke Missing Disk Stores
-
-This section applies to disk stores for which both of the following are true:
-
--   Disk stores that have the most recent copy of data for one or more regions or region buckets.
--   Disk stores that are unrecoverable, such as when you have deleted them, or their files are corrupted or on a disk that has had a catastrophic failure.
-
-When you cannot bring the latest persisted copy online, use the revoke command to tell the other members to stop waiting for it. Once the store is revoked, the system finds the remaining most recent copy of data and uses that.
-
-**Note:**
-Once revoked, a disk store cannot be reintroduced into the system.
-
-Use gfsh show missing-disk-stores to properly identify the disk store you need to revoke. The revoke command takes the disk store ID as input, as listed by that command.
-
-Example:
-
-``` pre
-gfsh>revoke missing-disk-store --id=60399215-532b-406f-b81f-9b5bd8d1b55a
-Missing disk store successfully revoked
-```

-Overflow and persistence use disk stores individually or together to store data.
-
-<a id="how_disk_stores_work__section_1A93EFBE3E514918833592C17CFC4C40"></a>
-Disk storage is available for these items:
-
--   **Regions**. Persist and/or overflow data from regions.
--   **Server’s client subscription queues**. Overflow the messaging queues to control memory use.
--   **Gateway sender queues**. Persist these for high availability. These queues always overflow.
--   **PDX serialization metadata**. Persist metadata about objects you serialize using Geode PDX serialization.
-
-Each member has its own set of disk stores, and they are completely separate from the disk stores of any other member. For each disk store, define where and how the data is stored to disk. You can store data from multiple regions and queues in a single disk store.
-
-This figure shows a member with disk stores D through R defined. The member has two persistent regions using disk store D and an overflow region and an overflow queue using disk store R.

-
-This list describes the items that Geode comprise the disk store:
-
--   The members that host the store, and information on their status, such as which members are online and which members are offline and time stamps.
--   A disk store identifier.
--   Which regions are in the disk store, specified by region name.
--   Colocated regions that the regions in the disk store are dependent upon.
--   A set of files that specify all keys for the regions, as well as all operations on the regions. Given both keys and operations, a region can be recreated when a member is restarted.
-
-Geode does not write indexes to disk.
-
-## <a id="how_disk_stores_work__section_C1A047CD5518499D94A0E9A0328F6DB8" class="no-quick-link"></a>Disk Store State
-
-The files for a disk store are used by Geode as a group. Treat them as a single entity. If you copy them, copy them all together. Do not change the file names.
-
-Disk store access and management differs according to whether the member is online or offline.
-
-While a member is running, its disk stores are online. When the member exits and is not running, its disk stores are offline.
-
--   Online, a disk store is owned and managed by its member process. To run operations on an online disk store, use API calls in the member process, or use the `gfsh` command-line interface.
--   Offline, the disk store is just a collection of files in the host file system. The files are accessible based on file system permissions. You can copy the files for backup or to move the member’s disk store location. You can also run some maintenance operations, such as file compaction and validation, by using the `gfsh` command-line interface. When offline, the disk store's information is unavailable to the distributed system. For partitioned regions, region data is split between multiple members, and therefore the start up of a member is dependent on and must wait for all members to be online. An attempt to access an entry that is stored on disk by an offline member results in a `PartitionOfflineException`.

-You can take several actions to optimize disk store use and data loading at startup.
-
-## <a id="syncing_offline_disk_store__section_7B95B20F07BD40699CDB7F3D6A93B905" class="no-quick-link"></a>Change Region Configuration
-
-When your disk store is offline, you can keep the configuration for its regions up-to-date with your `cache.xml` and API settings. The disk store retains region capacity and load settings, including entry map settings (initial capacity, concurrency level, load factor), LRU eviction settings, and the statistics enabled boolean. If the configurations do not match at startup, the `cache.xml` and API override any disk store settings and the disk store is automatically updated to match. So you do not need to modify your disk store to keep your cache configuration and disk store synchronized, but you will save startup time and memory if you do.
-
-For example, to change the initial capacity of the disk store:
-
-``` pre
-gfsh>alter disk-store --name=myDiskStoreName --region=partitioned_region 
---disk-dirs=/firstDiskStoreDir,/secondDiskStoreDir,/thirdDiskStoreDir 
---initialCapacity=20
-```
-
-To list all modifiable settings and their current values for a region, run the command with no actions specified:
-
-``` pre
-gfsh>alter disk-store --name=myDiskStoreName --region=partitioned_region
---disk-dirs=/firstDiskStoreDir,/secondDiskStoreDir,/thirdDiskStoreDir  
-```
-
-## <a id="syncing_offline_disk_store__section_0CA17ED106394686A1A5B30601758DA6" class="no-quick-link"></a>Take a Region Out of Your Cache Configuration and Disk Store
-
-You might remove a region from your application if you decide to rename it or to split its data into two entirely different regions. Any significant data restructuring can cause you to retire some data regions.
-
-This applies to the removal of regions while the disk store is offline. Regions you destroy through API calls or by `gfsh` are automatically removed from the disk store of online members.
-
-In your application development, when you discontinue use of a persistent region, remove the region from the member’s disk store as well.
-
-**Note:**
-Perform the following operations with caution. You are permanently removing data.
-
-You can remove the region from the disk store in one of two ways:
-
--   Delete the entire set of disk store files. Your member will initialize with an empty set of files the next time you and start it. Exercise caution when removing the files from the file system, as more than one region can be specified to use the same disk store directories.
--   Selectively remove the discontinued region from the disk store with a command such as:
-
-    ``` pre
-    gfsh>alter disk-store --name=myDiskStoreName --region=partitioned_region
-    --disk-dirs=/firstDiskStoreDir,/secondDiskStoreDir,/thirdDiskStoreDir --remove
-    ```
-
-To guard against unintended data loss, Geode maintains the region in the disk store until you manually remove it. Regions in the disk stores that are not associated with any region in your application are still loaded into temporary regions in memory and kept there for the life of the member. The system has no way of detecting whether the cache region will be created by your API at some point, so it keeps the temporary region loaded and available.

-You can configure Geode to write immediately to disk and you may be able to modify your operating system behavior to perform buffer flushes more frequently.
-
-Typically, Geode writes disk data into the operating system's disk buffers and the operating system periodically flushes the buffers to disk. Increasing the frequency of writes to disk decreases the likelihood of data loss from application or machine crashes, but it impacts performance. Your other option, which may give you better performance, is to use Geode's in-memory data backups. Do this by storing your data in multiple replicated regions or in partitioned regions that are configured with redundant copies. See [Region Types](../../developing/region_options/region_types.html#region_types).

-## <a id="disk_buffer_flushes__section_448348BD28B14F478D81CC2EDC6C7049" class="no-quick-link"></a>Modifying Disk Flushes for the Operating System
-
-You may be able to change the operating system settings for periodic flushes. You may also be able to perform explicit disk flushes from your application code. For information on these options, see your operating system's documentation. For example, in Linux you can change the disk flush interval by modifying the setting `/proc/sys/vm/dirty_expire_centiseconds`. It defaults to 30 seconds. To alter this setting, see the Linux documentation for `dirty_expire_centiseconds`.

-## <a id="disk_buffer_flushes__section_D1068505581A43EE8395DBE97297C60F" class="no-quick-link"></a>Modifying Geode to Flush Buffers on Disk Writes
-
-You can have Geode flush the disk buffers on every disk write. Do this by setting the system property `gemfire.syncWrites` to true at the command line when you start your Geode member. You can only modify this setting when you start a member. When this is set, Geode uses a Java `RandomAccessFile` with the flags "rwd", which causes every file update to be written synchronously to the storage device. This only guarantees your data if your disk stores are on a local device. See the Java documentation for `java.IO.RandomAccessFile`.
-
-To modify the setting for a Geode application, add this to the java command line when you start the member:
-
-``` pre
--Dgemfire.syncWrites=true
-```
-
-To modify the setting for a cache server, use this syntax:
-
-``` pre
-gfsh>start server --name=... --J=-Dgemfire.syncWrites=true
-```

-For offline operations, `gfsh` runs the command against the specified disk store and its specified directories. You must specify all directories for the disk store. For example:
-
-``` pre

-```
-
-Offline operations will not run on online disk stores. The tool locks the disk store while it is running, so the member cannot start in the middle of an operation.
-
-If you try to run an offline command for an online disk store, you get a message like this:
-
-``` pre
-gfsh>compact offline-disk-store --name=DEFAULT --disk-dirs=s1
-This disk store is in use by another process. "compact disk-store" can 
-be used to compact a disk store that is currently in use.

-
-At creation, each operation log is initialized at the disk store's `max-oplog-size`, with the size divided between the `crf` and `drf` files. When the oplog is closed, Apache Geode shrinks the files to the space used in each file.
-
-<a id="operation_logs__section_C0B1391492394A908577C29772902A42"></a>
-After the oplog is closed, Geode also attempts to create a `krf` file, which contains the key names as well as the offset for the value within the `crf` file. Although this file is not required for startup, if it is available, it will improve startup performance by allowing Geode to load the entry values in the background after the entry keys are loaded.
-
-When an operation log is full, Geode automatically closes it and creates a new log with the next sequence number. This is called *oplog rolling*. You can also request an oplog rolling through the API call `DiskStore.forceRoll`. You may want to do this immediately before compacting your disk stores, so the latest oplog is available for compaction.
-
-**Note:**
-Log compaction can change the names of the disk store files. File number sequencing is usually altered, with some existing logs removed or replaced by newer logs with higher numbering. Geode always starts a new log at a number higher than any existing number.
-
-This example listing shows the logs in a system with only one disk directory specified for the store. The first log (`BACKUPCacheOverflow_1.crf` and `BACKUPCacheOverflow_1.drf`) has been closed and the system is writing to the second log.
-
-``` pre
-bash-2.05$ ls -tlra

-drwxrwxr-x   2 person users       2560 Mar 22 13:57 .
-```
-
-The system rotates through all available disk directories to write its logs. The next log is always started in a directory that has not reached its configured capacity, if one exists.
-
-## <a id="operation_logs__section_8431984F4E6644D79292850CCA60E6E3" class="no-quick-link"></a>When Disk Store Oplogs Reach the Configured Disk Capacity
-
-If no directory exists that is within its capacity limits, how Geode handles this depends on whether automatic compaction is enabled.
-
--   If auto-compaction is enabled, Geode creates a new oplog in one of the directories, going over the limit, and logs a warning that reports:
-
-    ``` pre
-    Even though the configured directory size limit has been exceeded a 
-    new oplog will be created. The current limit is of XXX. The current 
-    space used in the directory is YYY.
-    ```
-
-    **Note:**
-    When auto-compaction is enabled, `dir-size` does not limit how much disk space is used. Geode will perform auto-compaction, which should free space, but the system may go over the configured disk limits.
-
--   If auto-compaction is disabled, Geode does not create a new oplog, operations in the regions attached to the disk store block, and Geode logs this error:
-
-    ``` pre
-    Disk is full and rolling is disabled. No space can be created
-    ```

-Optimize availability and performance by following the guidelines in this section.
-
-1.  Apache Geode recommends the use of `ext4` filesystems when operating on Linux or Solaris platforms. The `ext4` filesystem supports preallocation, which benefits disk startup performance. If you are using `ext3` filesystems in latency-sensitive environments with high write throughput, you can improve disk startup performance by setting the `maxOplogSize` (see the `DiskStoreFactory.setMaxOplogSize`) to a value lower than the default 1 GB and by disabling preallocation by specifying the system property `gemfire.preAllocateDisk=false` upon Geode process startup.
-2.  When you start your system, start all the members that have persistent regions at roughly the same time. Create and use startup scripts for consistency and completeness.
-3.  Shut down your system using the gfsh `shutdown` command. This is an ordered shutdown that positions your disk stores for a faster startup.
-4.  Configure critical usage thresholds (`disk-usage-warning-percentage` and `disk-usage-critical-percentage`) for the disk. By default, these are set to 80% for warning and 99% for errors that will shut down the cache.
-5.  Decide on a file compaction policy and, if needed, develop procedures to monitor your files and execute regular compaction.
-6.  Decide on a backup strategy for your disk stores and follow it. You can back up a running sytem by using the `backup                     disk-store` command.
-7.  If you remove any persistent region or change its configuration while your disk store is offline, consider synchronizing the regions in your disk stores.

-In addition to the disk stores you specify, Apache Geode has a default disk store that it uses when disk use is configured with no disk store name specified. You can modify default disk store behavior.
-
--   **[Designing and Configuring Disk Stores](../../managing/disk_storage/using_disk_stores.html)**
-
-    You define disk stores in your cache, then you assign them to your regions and queues by setting the `disk-store-name` attribute in your region and queue configurations.
-
--   **[Disk Store Configuration Parameters](../../managing/disk_storage/disk_store_configuration_params.html)**
-
-    You define your disk stores by using the `gfsh create disk-store` command or in `<disk-store>` subelements of your cache declaration in `cache.xml`. All disk stores are available for use by all of your regions and queues.
-
--   **[Modifying the Default Disk Store](../../managing/disk_storage/using_the_default_disk_store.html)**
-
-    You can modify the behavior of the default disk store by specifying the attributes you want for the disk store named "DEFAULT".

-This section describes what happens during startup and shutdown and provides procedures for those operations.
-
-## Start Up
-
-When you start a member with a persistent region, the data is retrieved from disk stores to recreate the member’s persistent region. If the member does not hold all of the most recent data for the region, then other members have the data, and region creation blocks, waiting for the those other members. A partitioned region with colocated entries also blocks on start up, waiting for the entries of the colocated region to be available. A persistent gateway sender is treated the same as a colocated region, so it can also block region creation.
-
-With a log level of info or below, the system provides messaging about the wait. Here, the disk store for server2 has the most recent data for the region, and server1 is waiting for server2.
-
-``` pre
-Region /people has potentially stale data.
-It is waiting for another member to recover the latest data.
-My persistent id:
-
-  DiskStore ID: 6893751ee74d4fbd-b4780d844e6d5ce7
-  Name: server1
-  Location: /192.0.2.0:/home/dsmith/server1/.
-
-Members with potentially new data:
-[
-  DiskStore ID: 160d415538c44ab0-9f7d97bae0a2f8de
-  Name: server2
-  Location: /192.0.2.0:/home/dsmith/server2/.
-]
-Use the "gfsh show missing-disk-stores" command to see all disk stores
-that are being waited on by other members.
-```
-
-When the most recent data is available, the system updates the region, logs a message, and continues the startup.
-
-``` pre
-[info 2010/04/09 10:52:13.010 PDT CacheRunner <main> tid=0x1]    
-   Done waiting for the remote data to be available.
-```
-
-If the member's disk store has data for a region that is never created, the data remains in the disk store.
-
-Each member’s persistent regions load and go online as quickly as possible, not waiting unnecessarily for other members to complete. For performance reasons, these actions occur asynchronously:
-
--   Once at least one copy of each and every bucket is recovered from disk, the region is available. Secondary buckets will load asynchronously.
--   Entry keys are loaded from the key file in the disk store before considering entry values. Once all keys are loaded, Geode loads the entry values asynchronously. If a value is requested before it has loaded, the value will immediately be fetched from the disk store.
-
-## <a id="starting_system_with_disk_stores__section_D0A7403707B847749A22BF9221A2C823" class="no-quick-link"></a>Start Up Procedure
-
-To start a system with disk stores:
-
-1.  **Start all members with persisted data first and at the same time**. Exactly how you do this depends on your members. Make sure to start members that host colocated regions, as well as persistent gateway senders.
-
-    While they are initializing their regions, the members determine which have the most recent region data, and initialize their regions with the most recent data.
-
-    For replicated regions, where you define persistence only in some of the region's host members, start the persistent replicate members prior to the non-persistent replicate members to make sure the data is recovered from disk.
-
-    This is an example bash script for starting members in parallel. The script waits for the startup to finish. It exits with an error status if one of the jobs fails.
-
-    ``` pre
-    #!/bin/bash
-    ssh servera "cd /my/directory; gfsh start server --name=servera &
-    ssh serverb "cd /my/directory; gfsh start server --name=serverb &
-
-    STATUS=0;
-    for job in `jobs -p`
-    do
-    echo $job
-    wait $job;
-    JOB_STATUS=$?;
-    test $STATUS -eq 0 && STATUS=$JOB_STATUS;
-    done
-    exit $STATUS;
-    ```
-
-2.  **Respond to blocked members**. When a member blocks waiting for more recent data from another member, the member waits indefinitely rather than coming online with stale data. Check for missing disk stores with the `gfsh show                             missing-disk-stores` command. See [Handling Missing Disk Stores](handling_missing_disk_stores.html#handling_missing_disk_stores).
-    -   If no disk stores are missing, the cache initialization must be slow for some other reason. Check the information on member hangs in [Diagnosing System Problems](../troubleshooting/diagnosing_system_probs.html#diagnosing_system_probs).
-    -   If disk stores are missing that you think should be there:
-        -   Make sure you have started the member. Check the logs for any failure messages. See [Logging](../logging/logging.html#concept_30DB86B12B454E168B80BB5A71268865).
-        -   Make sure your disk store files are accessible. If you have moved your member or disk store files, you must update your disk store configuration to match.
-    -   If disk stores are missing that you know are lost, because you have deleted them or their files are otherwise unavailable, revoke them so the startup can continue.
-
-## <a id="starting_system_with_disk_stores__section_5E32F488EB5D4E74AAB6BF394E4329D6" class="no-quick-link"></a>Example Startup to Illustrate Ordering
-
-The following lists the two possibilities for starting up a replicated persistent region after a shutdown. Assume that Member A (MA) exits first, leaving persisted data on disk for RegionP. Member B (MB) continues to run operations on RegionP, which update its disk store and leave the disk store for MA in a stale condition. MB exits, leaving the most up-to-date data on disk for RegionP.
-
--   Restart order 1
-    1.  MB is started first. MB identifies that it has the most recent disk data for RegionP and initializes the region from disk. MB does not block.
-    2.  MA is started, recovers its data from disk, and updates region data as needed from the data in MB.
--   Restart order 2
-    1.  MA is started first. MA identifies that it does not have the most recent disk data and blocks, waiting for MB to start before recreating RegionP in MA.
-    2.  MB is started. MB identifies that it has the most recent disk data for RegionP and initializes the region from disk.
-    3.  MA recovers its RegionP data from disk and updates region data as needed from the data in MB.
-
-## Shutdown
-
-If more than one member hosts a persistent region or queue, the order in which the various members shut down may be significant upon restart of the system. The last member to exit the system or shut down has the most up-to-date data on disk. Each member knows which other system members were online at the time of exit or shutdown. This permits a member to acquire the most recent data upon subsequent start up.
-
-For a replicated region with persistence, the last member to exit has the most recent data.
-
-For a partitioned region every member persists its own buckets. A shutdown using `gfsh shutdown` will synchronize the disk stores before exiting, so all disk stores hold the most recent data. Without an orderly shutdown, some disk stores may have more recent bucket data than others.
-
-The best way to shut down a system is to invoke the `gfsh shutdown` command with all members running. All online data stores will be synchronized before shutting down, so all hold the most recent data copy. To shut down all members other than locators:
-
-``` pre
-gfsh>shutdown
-```
-
-To shut down all members, including locators:
-
-``` pre
-gfsh>shutdown --include-locators=true
-```

-You define disk stores in your cache, then you assign them to your regions and queues by setting the `disk-store-name` attribute in your region and queue configurations.
-
-**Note:**
-Besides the disk stores you specify, Apache Geode has a default disk store that it uses when disk use is configured with no disk store name specified. By default, this disk store is saved to the application’s working directory. You can change its behavior, as indicated in [Create and Configure Your Disk Stores](using_disk_stores.html#defining_disk_stores__section_37BC5A4D84B34DB49E489DD4141A4884) and [Modifying the Default Disk Store](using_the_default_disk_store.html#using_the_default_disk_store).

-## <a id="defining_disk_stores__section_0CD724A12EE4418587046AAD9EEC59C5" class="no-quick-link"></a>Design Your Disk Stores
-
-Before you begin, you should understand Geode [Basic Configuration and Programming](../../basic_config/book_intro.html).
-
-1.  Work with your system designers and developers to plan for anticipated disk storage requirements in your testing and production caching systems. Take into account space and functional requirements.
-    -   For efficiency, separate data that is only overflowed in separate disk stores from data that is persisted or persisted and overflowed. Regions can be overflowed, persisted, or both. Server subscription queues are only overflowed.
-    -   When calculating your disk requirements, figure in your data modification patterns and your compaction strategy. Geode creates each oplog file at the max-oplog-size, which defaults to 1 GB. Obsolete operations are only removed from the oplogs during compaction, so you need enough space to store all operations that are done between compactions. For regions where you are doing a mix of updates and deletes, if you use automatic compaction, a good upper bound for the required disk space is
-
-        ``` pre
-        (1 / (1 - (compaction_threshold/100)) ) * data size
-        ```
-
-        where data size is the total size of all the data you store in the disk store. So, for the default compaction-threshold of 50, the disk space is roughly twice your data size. Note that the compaction thread could lag behind other operations, causing disk use to rise above the threshold temporarily. If you disable automatic compaction, the amount of disk required depends on how many obsolete operations accumulate between manual compactions.
-
-2.  Work with your host system administrators to determine where to place your disk store directories, based on your anticipated disk storage requirements and the available disks on your host systems.
-    -   Make sure the new storage does not interfere with other processes that use disk on your systems. If possible, store your files to disks that are not used by other processes, including virtual memory or swap space. If you have multiple disks available, for the best performance, place one directory on each disk.
-    -   Use different directories for different members. You can use any number of directories for a single disk store.
-
-## <a id="defining_disk_stores__section_37BC5A4D84B34DB49E489DD4141A4884" class="no-quick-link"></a>Create and Configure Your Disk Stores
-
-1.  In the locations you have chosen, create all directories you will specify for your disk stores to use. Geode throws an exception if the specified directories are not available when a disk store is created. You do not need to populate these directories with anything.
-2.  Open a `gfsh` prompt and connect to the distributed system.
-3.  At the `gfsh` prompt, create and configure a disk store:
-    -  Specify the name (`--name`) of the disk-store.
-
-        -   Choose disk store names that reflect how the stores should be used and that work for your operating systems. Disk store names are used in the disk file names:
-
-            -   Use disk store names that satisfy the file naming requirements for your operating system. For example, if you store your data to disk in a Windows system, your disk store names could not contain any of these reserved characters, &lt; &gt; : " / \\ | ? \*.
-
-            -   Do not use very long disk store names. The full file names must fit within your operating system limits. On Linux, for example, the standard limitation is 255 characters.
-
-        ``` pre
-        gfsh>create disk-store --name=serverOverflow --dir=c:\overflow_data#20480 
-        ```
-    -  Configure the directory locations (`--dir`) and the maximum space to use for the store (specified after the disk directory name by \# and the maximum number in megabytes).
-
-        ``` pre
-        gfsh>create disk-store --name=serverOverflow --dir=c:\overflow_data#20480
-        ```
-    -  Optionally, you can configure the store’s file compaction behavior. In conjunction with this, plan and program for any manual compaction.  Example:
-
-        ``` pre
-        gfsh>create disk-store --name=serverOverflow --dir=c:\overflow_data#20480 \
-        --compaction-threshold=40 --auto-compact=false --allow-force-compaction=true
-        ```
-    -  If needed, configure the maximum size (in MB) of a single oplog. When the current files reach this size, the system rolls forward to a new file. You get better performance with relatively small maximum file sizes.  Example:
-
-        ``` pre
-        gfsh>create disk-store --name=serverOverflow --dir=c:\overflow_data#20480 \
-        --compaction-threshold=40 --auto-compact=false --allow-force-compaction=true \
-        --max-oplog-size=512
-        ```
-    -  If needed, modify queue management parameters for asynchronous queueing to the disk store. You can configure any region for synchronous or asynchronous queueing (region attribute `disk-synchronous`). Server queues and gateway sender queues always operate synchronously. When either the `queue-size` (number of operations) or `time-interval` (milliseconds) is reached, enqueued data is flushed to disk. You can also synchronously flush unwritten data to disk through the `DiskStore` `flushToDisk` method.  Example:
-
-        ``` pre
-        gfsh>create disk-store --name=serverOverflow --dir=c:\overflow_data#20480 \
-        --compaction-threshold=40 --auto-compact=false --allow-force-compaction=true \
-        --max-oplog-size=512 --queue-size=10000 --time-interval=15
-        ```
-    -  If needed, modify the size (specified in bytes) of the buffer used for writing to disk.  Example:
-
-        ``` pre
-        gfsh>create disk-store --name=serverOverflow --dir=c:\overflow_data#20480 \
-        --compaction-threshold=40 --auto-compact=false --allow-force-compaction=true \
-        --max-oplog-size=512 --queue-size=10000 --time-interval=15 --write-buffer-size=65536
-        ```
-    -  If needed, modify the `disk-usage-warning-percentage` and `disk-usage-critical-percentage` thresholds that determine the percentage (default: 90%) of disk usage that will trigger a warning and the percentage (default: 99%) of disk usage that will generate an error and shut down the member cache.  Example:
-
-        ``` pre
-        gfsh>create disk-store --name=serverOverflow --dir=c:\overflow_data#20480 \
-        --compaction-threshold=40 --auto-compact=false --allow-force-compaction=true \
-        --max-oplog-size=512 --queue-size=10000 --time-interval=15 --write-buffer-size=65536 \
-        --disk-usage-warning-percentage=80 --disk-usage-critical-percentage=98
-        ```
-
-The following is the complete disk store cache.xml configuration example:
-
-``` pre
-<disk-store name="serverOverflow" compaction-threshold="40" 
-           auto-compact="false" allow-force-compaction="true"
-        max-oplog-size="512" queue-size="10000"  
-        time-interval="15" write-buffer-size="65536"
-        disk-usage-warning-percentage="80"
-        disk-usage-critical-percentage="98">
-       <disk-dirs>
-              <disk-dir>c:\overflow_data</disk-dir>
-              <disk-dir dir-size="20480">d:\overflow_data</disk-dir>
-       </disk-dirs>
-</disk-store>
-```
-
-**Note:**
-As an alternative to defining cache.xml on every server in the cluster-- if you have the cluster configuration service enabled, when you create a disk store in `gfsh`, you can share the disk store's configuration with the rest of cluster. See [Overview of the Cluster Configuration Service](../../configuring/cluster_config/gfsh_persist.html).
-
-## Modifying Disk Stores
-
-You can modify an offline disk store by using the [alter disk-store](../../tools_modules/gfsh/command-pages/alter.html#topic_99BCAD98BDB5470189662D2F308B68EB) command. If you are modifying the default disk store configuration, use "DEFAULT" as the disk-store name.

-
-The following are examples of using already created and named disk stores for Regions, Queues, and PDX Serialization.
-
-Example of using a disk store for region persistence and overflow:
-
--   gfsh:
-
-    ``` pre
-    gfsh>create region --name=regionName --type=PARTITION_PERSISTENT_OVERFLOW \
-    --disk-store=serverPersistOverflow
-    ```
-
--   cache.xml
-
-    ``` pre
-    <region refid="PARTITION_PERSISTENT_OVERFLOW" disk-store-name="persistOverflow1"/>
-    ```
-
-Example of using a named disk store for server subscription queue overflow (cache.xml):
-
-``` pre
-<cache-server port="40404">
-   <client-subscription 
-      eviction-policy="entry" 
-      capacity="10000"
-      disk-store-name="queueOverflow2"/>
-</cache-server>
-```
-
-Example of using a named disk store for PDX serialization metadata (cache.xml):
-
-``` pre
-<pdx read-serialized="true" 
-    persistent="true" 
-    disk-store-name="SerializationDiskStore">
-</pdx>
-```
-
-## <a id="defining_disk_stores__config-disk-store-gateway" class="no-quick-link"></a>Configuring Disk Stores on Gateway Senders
-
-Gateway sender queues are always overflowed and may be persisted. Assign them to overflow disk stores if you do not persist, and to persistence disk stores if you do.
-
-Example of using a named disk store for gateway sender queue persistence:
-
--   gfsh:
-
-    ``` pre
-    gfsh>create gateway-sender --id=persistedSender1 --remote-distributed-system-id=1 \
-    --enable-persistence=true --disk-store-name=diskStoreA --maximum-queue-memory=100  
-    ```
-
--   cache.xml:
-
-    ``` pre
-    <cache>
-      <gateway-sender id="persistedsender1" parallel="true" 
-       remote-distributed-system-id="1"
-       enable-persistence="true"
-       disk-store-name="diskStoreA"
-       maximum-queue-memory="100"/> 
-       ... 
-    </cache>
-    ```
-
-Examples of using the default disk store for gateway sender queue persistence and overflow:
-
--   gfsh:
-
-    ``` pre
-    gfsh>create gateway-sender --id=persistedSender1 --remote-distributed-system-id=1 \
-    --enable-persistence=true --maximum-queue-memory=100 
-    ```
-
--   cache.xml:
-
-    ``` pre
-    <cache>
-      <gateway-sender id="persistedsender1" parallel="true" 
-       remote-distributed-system-id="1"
-       enable-persistence="true"
-       maximum-queue-memory="100"/> 
-       ... 
-    </cache>
-    ```

-Whenever you use disk stores without specifying the disk store to use, Geode uses the disk store named "DEFAULT".
-
-For example, these region and queue configurations specify persistence and/or overflow, but do not specify the disk-store-name. Because no disk store is specified, these use the disk store named "DEFAULT".

-
-Geode initializes the default disk store with the default disk store configuration settings. You can modify the behavior of the default disk store by specifying the attributes you want for the disk store named "DEFAULT". The only thing you can’t change about the default disk store is the name.
-
-The following example changes the default disk store to allow manual compaction and to use multiple, non-default directories:
-
-cache.xml:
-
-``` pre
-<disk-store name="DEFAULT" allow-force-compaction="true">
-     <disk-dirs>
-        <disk-dir>/export/thor/customerData</disk-dir>

-The `validate offline-disk-store` command verifies the health of your offline disk store and gives you information about the regions in it, the total entries, and the number of records that would be removed if you compacted the store.
-
-Use this command at these times:
-
--   Before compacting an offline disk store to help decide whether it’s worth doing.
--   Before restoring or modifying a disk store.
--   Any time you want to be sure the disk store is in good shape.
