This bug was initially created as a copy of Bug #2027826 I am copying this bug because: Requested for backport This bug was initially created as a copy of Bug #2026007 I am copying this bug because: An OCS operator update is needed to expose an option to force removal of an OSD if Ceph indicates the OSD is not safe-to-destroy. If https://bugzilla.redhat.com/show_bug.cgi?id=2027396 is approved for 4.9.z, we will also need this for 4.9.z. Description of problem (please be detailed as possible and provide log snippets): Use ceph 'osd safe-to-destroy' and 'osd ok-to-stop' feature in OSD purge job [1] mgr: implement 'osd safe-to-destroy' and 'osd ok-to-stop' commands https://github.com/ceph/ceph/pull/16976 An osd is safe to destroy if we have osd_stat for it osd_stat indicates no pgs stored all pgs are known no pgs map to it i.e., overall data durability will not be affected An OSD is ok to stop if we have the pg stats we need no PGs will drop below min_size i.e., availability won't be immediately compromised
