Subject [jira] [Updated] (AMQ-6441) Incorrect File System Size Reported with Amazon Elastic File System (EFS)
Date Fri, 23 Sep 2016 14:31:20 GMT

     [ https://issues.apache.org/jira/browse/AMQ-6441?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Ismail Bhana updated AMQ-6441:
------------------------------
    Description: 
I've set up Active MQ in production with a shared file system master/slave configuration (KahaDB).
I've set everything up and mounted the EFS on both EC2 instances. 

When I check the disk free stats I get 8 exabytes for the shared file system: 

{code}
$ df -h 
eu-west-1a.***.efs.eu-west-1.amazonaws.com:/  8.0E     0  8.0E   0% /mnt/efs 
{code}

Unfortunately, ActiveMQ cannot interpret this number (8 exabytes). This may be due to integer
truncation.

Here is a snippet of the log:

{code}
Store limit is 102400 mb (current store usage is 0 mb). The data directory: /mnt/efs/kahadb
only has -8796093022208 mb of usable space - resetting to maximum available disk space: -8796093022207
mb 
Store limit is -8796093022207 mb, whilst the max journal file size for the store is: 32 mb,
the store will not accept any data when used. 
{code}
