4. Start the VM

Anush, this doesn't look like a gluster issue... Can you confirm the behavior on backend FS itself?

Comment 3 Anush Shetty 2012-11-06 09:14:33 UTC
Amar, how to try it directly on the backend FS? Should we try it on a VM hosted on a NFS export storage domain?

Comment 4 Amar Tumballi 2012-11-06 11:35:12 UTC
Anush, yes, you can try it on NFS data store, also you can use backend FS directly using posixfs to mount a XFS volume (on /dev/sd*N)... But for verification, NFS data store is good enough.

Also as Yaniv mentioned in the call, it could have got fixed with later RHEV-H versions, as there was some similar bug there.

Comment 5 Anush Shetty 2012-11-07 11:32:14 UTC
Unable to reproduce this issue with the latest build, glusterfs-3.3.0rhsvirt1-8.el6rhs.x86_64
