We have ceph 12.2.4 cephfs with two active MDS server and directory are pinned
to MDS servers. Yesterday MDS server crashed. Once all fuse clients have
unmounted, we bring back MDS online. Both MDS are active now.
Once It came back, we started to see one MDS is Readonly.

It health waring I see
health: HEALTH_WARN
1 MDSs are read only
1 MDSs behind on trimming

Will ceph daemon mds.x scrub_path / force recursive repair will fix?. Or
offline data-scan need to be done
