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:


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?

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.

>            Assignee: Dmitriy Pavlov
>            Priority: Blocker

> 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.
