Hello,
when we remove OSDs from the cluster, the cluster status and PG states should be a concern before doing anything. 

IE we should validate that all the PGs are active+clean before removing an OSD. Simply doing this and validating that the Ceph cluster is healthy enough to remove OSDs can prevent potential data loss situations.

Additionally, if we are to remove multiple OSD, it's important that the PGs in the Ceph cluster are active+clean each time before we  remove any subsequent OSD.

Can this be triaged? It hasn't seen any movement for a month, and it's on the watchlist.
TIA,
Y.
