| Fixed In Version: | glusterfs-3.8.4-18.1 | Doc Type: | Bug Fix |
| Doc Text: |
Previously, creation of snapshot sometimes failed on a geo-replicated volume, even after stopping the session. This was due to a bug in the way the gusterd builds up state of in-memory active geo-replication sessions. With this fix, you can successfully create snapshots of a geo-replicated volume.

Minor comment. Snapshot was not always failing. You can add the word 'sometimes'.
