Prashant Pogde commented on HDDS-8870:
--------------------------------------
This is expected. Snapshot ls and snapshot diff are passive commands that do
not modify the snapshot state of the system. I will resolved this.
> [snapshot] Snapshot 'ls' and 'snapshotDiff' commands are still working when
> ozone.filesystem.snapshot.enabled is set to false

> URL: https://issues.apache.org/jira/browse/HDDS-8870
> Project: Apache Ozone
> Issue Type: Bug
> Components: Ozone Manager
> Reporter: Jyotirmoy Sinha
> Priority: Major
> Labels: ozone-snapshot
>
> Steps :
> # Create volume, bucket, key and take snapshot
> # Set ozone.filesystem.snapshot.enabled=false in cluster, and restart/deploy
> client config.
> # Create/delete snapshots are failing due to snapshot not enabled
> {code:java}
> [root@jssnap-1 ~]# ozone sh snapshot create vol1/buck1 snap4
> FEATURE_NOT_ENABLED Operation OMSnapshotCreateRequest.preExecute(..) cannot
> be invoked because Ozone snapshot feature is disabled.
> [root@jssnap-1 ~]# ozone sh snapshot delete vol1/buck1 snap3
> FEATURE_NOT_ENABLED Operation OMSnapshotDeleteRequest.preExecute(..) cannot
> be invoked because Ozone snapshot feature is disabled.
> [root@jssnap-1 ~]# ozone sh snapshot snapshotDiff vol1/buck1 snap1 snap3
> [root@jssnap-1 ~]# ozone fs -createSnapshot ofs://ozone1/vol1/buck1 snap4
> createSnapshot: Operation OMSnapshotCreateRequest.preExecute(..) cannot be
> invoked because Ozone snapshot feature is disabled. {code}
> # Snapshot ls and snapshotDiff commands are still working
> {code:java}
> [root@jssnap-1 ~]# ozone sh snapshot ls vol1/buck1
