Comment 0 for bug 1473044

Description:

With gluster version 3.7.1, The name of snapshot taken on gluster volume has time stamp appended to it. The driver looks for snapshots with just the name and this mismatch prevents 'manila snapshot delete'.

Appending timestamp to the name of snapshot was introduced as a fix to this bug
