Data migration from old indexer to the new one fails.

[gauravmsharma]

While upgrading my indexers from 7.0 to 8.0 the data disk migration for hotwarm, cold and thawed db is failing with message:

homePath='/var/opt/splunk/db/_audit' of index=_audit on unusable filesystem.
Validating databases (splunkd validatedb) failed with code '1'. If you cannot resolve the issue(s) above after consulting documentation, please file a case online at http://www.splunk.com/page/submit_issue
Error running pre-start tasks

The mount command output shows the disk being rw

/dev/xvde on /var/opt/splunk/thaweddb type ext4 (rw,relatime,seclabel,data=ordered)
/dev/xvdd on /var/opt/splunk/colddb type ext4 (rw,relatime,seclabel,data=ordered)
/dev/xvdc on /var/opt/splunk/db type ext4 (rw,relatime,seclabel,data=ordered)

Also fdisk -l command show these disk are attached ok as well.

I have tried implementing the bypass OPTIMISTIC_ABOUT_FILE_LOCKING=1, that too does not works. Do you have any way go for this?

It sounds like you have consulted the documentation, so the next step is to file a case online at http://www.splunk.com/page/submit_issue

They'll be able to give this the attention it needs probably better than we could.  Please post back what they found as an answer here, so that others may learn from it too!
