Description RamaKasturi 2015-04-28 05:16:15 UTC

Description of problem:
User should not be able to restore a snapshot while rebalance/remove-brick is running on the volume.

Version-Release number of selected component (if applicable):
ovirt-engine-3.6.0-0.0.master.20150420232310.gite30f655.el6.noarch

How reproducible:
Always

Steps to Reproduce:
1. create a volume.
2. start remove-brick / rebalance on the volume.
3. Now try restoring a snapshot.

Actual results:
Engine fails with error Error while executing action Restore volume snapshot:[]

Expected results:
Restore operation should not be allowed from UI when remove-brick or rebalance is going on the volume.

Comment 2 RamaKasturi 2015-05-21 05:15:42 UTC

Moving this bug back because of the error message mapping issue.

Following gets displayed in UI when user tries to restore the snapshot when rebalance or remove brick is running on the volume.

Error while executing action:

VAR_ACTION_RESTORE
cannot ${action} ${type}. A task is in progress on the volume ${volumename} in cluster ${vdsGroup}.

It would be good to display what kind of task is running instead of saying task is in progress.

ovirt-3.6.0-3 release

Comment 4 RamaKasturi 2016-02-02 12:26:15 UTC

Tested with RHEV 3.6.2.6 and RHGS Nightly ( glusterfs-3.7.5-17.el7rhgs )

when rebalance is running on a volume, snapshot restore fails with error "Error while exectuing action: Cannot restore Gluster Volume Snapshot. A rebalance operation is in progress on the volume <vol_name> cluster <clustername>

when remove-brick is running on a volume, snapshot restore fails with error "Error while executing action: Cannot restore Gluster Volume Snapshot. A remove_brick operation is in progress on the volume <vol_name> in cluster <cluster_name>"
