### Fixed Bugs and issues

1. Backup failing on cinder backend Fiber Channel.
2. Single VM backup (configurable) at a time out of workload having multiple VMs.
3. Snapshot and Selective/One Click Restore failing on quobyte.
4. Inplace restore fails saying no space left on device.
5. Specific workload fails to be restored; says VMDiskResourceSnap could not be found.
6. Restores are failing; error says security group rules already exist.
7. Snapshot intermittently fails with IO error while backup uploading.
8. Stopping multipath volumes is taking huge time.
9. Upgrading or deploying RHOSP 16.2.5 results in TrilioVaultWLM service and respective endpoints disappearing.

### Known issues

**Deleting snapshots show status as available in horizon UI**

Observation : Snapshot for which delete operation is in-progress from UI , its status is showing as available instead deleting.

Workaround:

Wait for sometime to complete all the delete operations.Eventually all the snapshots will be deleted successfully.
