Added a PR: https://github.com/openshift/ocs-operator/pull/832 PS: PR is still a WIP, as the changes are being tested (and further changes anticipated) PR tested. Both RBD and CephFS snapshotter features are working fine. Removed the WIP tag (from the PR). But we have to document clearly that, snapshotter feature will work only when the remote ceph cluster supports 'ceph fs subvolume info' command. @muagarwa ^^^ (In reply to arun kumar mohan from comment #6) > PR tested.

I hope cephfs and rbd are independent... right ? Is there a special restriction for rbd too ? AFAIK, it should fail, but Madhu will be a better person to answer this... @mrajanna , can you take a look... Thanks Madhu. The fix is merged in the master. Created a backport PR for release-4.6: https://github.com/openshift/ocs-operator/pull/867 Backport complete, changes merged to release-4.6 branch. As expressed earlier, this requires a clear documentation that states, for `cephfs` snapshotter to work we require a remote ceph cluster with `subvolume info` command support. As Madhu mentioned, RBD snapshotter works fine and has no dependency. @muagarwa can you please have a look. PS: tried to add `requires_doc +` ack, but don't have enough privilages. Arun, I have set require_doc_text to ? (it can be set to + only by doc team) Anjana, before Arun fills the doc text I have one query: Does this need a separate documentation BZ or can be added as a release note here itself. Added the doc_text. Please take a look Yes Neha, we don't need the doc text for the fix because this is a feature bug. We still need to document the minimum ceph version for external cluster and that we are already doing via https://bugzilla.redhat.com/show_bug.cgi?id=1892819 Resetting the doc text to '-' Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.
