            Bug ID: 1482023
           Summary: snpashots issues with other processes accessing the
                    mounted brick snapshots
           Product: GlusterFS
           Version: mainline
         Component: snapshot
          Assignee: bugs at gluster.org
          Reporter: sunkumar at redhat.com
                CC: bugs at gluster.org



Description of problem:

By default, GlusterFS does mount even deactivated snapshot(s) under
/run/gluster/snaps. Since we do have a mount, there is a possibility that some
process may access the mount, causing issues when trying to umount the volume
for instance when deleting the snapshot.


How reproducible:
100%

Steps to Reproduce:
1. Create a snapshot
2. Check for mount point
3. Deactivate a snapshot
4. Check for mount point

Actual results:

1. Newly created snapshot volume is getting listed in mount point.
2. After deactivation of snapshot volume is still present in mount point.

Expected results:

1. Newly created snapshot volume should not be listed in mount point, It should
list only after activating the snapshot volume.
2. After deactivation of snapshot volume, mount point should not be present.
