Patrick, can someone from cephfs take a look at this health warning?
Comment 7 Patrick Donnelly 2021-08-02 21:08:00 UTC 
If it reoccurs, please collect `ceph health detail`, `ceph fs dump`, and a perf dump of the mds `ceph daemon mds.<X> perf dump` (in a debug sidecar container).

> Q. Is there any workaround we can try on this OCS platform to get ceph status healthy?

You can try disabling standby replay:

> ceph fs set <fs_name> allow_standby_replay false

Rook may re-enable it though but it will hopefully get you to a state that the cluster can be upgraded.
