This doesn't look like a Heketi bug, right?

Comment 5 Luis Pabón 2016-07-19 00:38:49 UTC

Moved it to RHGS GlusterFS container

Comment 6 Luis Pabón 2016-07-20 13:50:30 UTC

Pointed out by Humble and Ashiq, Heketi needs to use /dev/mapper/... device nodes in the fstab.

Comment 8 Mohamed Ashiq 2016-07-20 17:59:35 UTC

Luis,

Also merge this PR(https://github.com/heketi/heketi/pull/440) to update templates.

Comment 11 Neha 2016-07-23 13:20:55 UTC

With latest build:

rhgs-server-docker-3.1.3-13
rhgs3-rhgs-volmanager-rhel7-3.1.3-12

Don;t see data loss , also fstab path is changed to /dev/mapper..

cat /var/lib/heketi/fstab  
/dev/mapper/vg_5d59ca08593a21a0b5932315de85c919-brick_2b982a20aff0c7db0c1874463d44478b /var/lib/heketi/mounts/vg_5d59ca08593a21a0b5932315de85c919/brick_2b982a20aff0c7db0c1874463d44478b xfs rw,inode64,noatime,nouuid 1 2
