Comment 1 RamaKasturi 2015-04-14 09:04:42 UTC

Verified and works fine with build ovirt-engine-3.6.0-0.0.master.20150412172306.git55ba764.el6.noarch.

User is able to restore a snapshot and following event message gets displayed during restore operation.

1) Gluster volume <vol1> stopped.
2) Detected brick <brick_name> removed from volume <vol_name> of cluster <cluster_name> and removed it from engine DB for all the bricks in the volume.
3) Detected new brick <new brick_name> on volume <vol_name> of cluster <cluster_name> and added it to engine DB.
4) Detected option features.barrier=disable reset on volume <vol_name> of cluster <cluster_name> and removed it from engine DB.
5) Gluster volume <vol_name> started.
6) Restored the volume <vol_name> to the state of gluster volume snapshot <snap_name>
