If storage becomes unavailable, the volume actions fail with error_deleting message.
Workaround: Run gluster volume delete VOLNAME force to forcefully delete the volume.
BZ#1062848
When a nova instance is rebooted while rebalance is in progress on the Red Hat Gluster Storage volume, the root file system will be mounted as read-only after the instance comes back up. Corruption messages are also seen on the instance.
