Subject [jira] [Commented] (IGNITE-6285) Enhance persistent store paths on start
Date Wed, 04 Oct 2017 22:03:00 GMT

    [ https://issues.apache.org/jira/browse/IGNITE-6285?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16192119#comment-16192119

Denis Magda commented on IGNITE-6285:
-------------------------------------

[~dpavlov],

Thinking of a high level documentation, the user has to know:
* how to start nodes from different clusters on a single box. They need to specify unique
paths for storage files.
* how to tackle the error described as Option 3 on wiki.
* how to bind storage files to specific node instance (consistent ID option).

Could you put all this together under this doc section?
https://apacheignite.readme.io/v2.2/docs/ignite-persistence-23#section-configuration

That page is hidden and will be released along with 2.3. Provided you with required permissions.

Don't close this ticket until the docs are ready.

> As per this thread - http://apache-ignite-users.70518.x6.nabble.com/Specifying-location-of-persistent-storage-location-td16636i20.html
> Ignite may switch storage path in case of changing DHCP lease or similar which can lead
to consistent ID change.
> In order to help user in spotting the issue Ignite may output the following to the logs:
> # Output the store path and tell its (1) size or state that it is empty and (2) last
data file modification date.
> # Output warning if there are other non-empty storage folders under work directory with
their sizes and dates.
