Hey everyone. Inside of cephfs, I have a directory which I setup a directory layout field to use an erasure coded (CLAY) pool, specific to the task. The rest of my cephfs is using normal replication. Fast forward some time, and the EC directory has been used pretty extensively, and through some bad luck and poor timing, ~200pgs are in an incomplete state, and the OSDs are completely gone and unrecoverable. (Specifically OSD 31 and 34, not that it matters at this point) # ceph pg ls incomplete --> is attached for reference. Fortunately, it's primarily (only) my on-site backups, and other replaceable data inside of I tried for a few days to recover the PGs: - Recreate blank OSDs with correct ID (was blocked by non-existant OSDs) - Deep Scrub - osd_find_best_info_ignore_history_les = true (`pg query` was showing related error) etc. I've finally just accepted this pool to be a lesson learned, and want to get the rest of my cephfs back to normal. My questions: -- `ceph osd force-create-pg` doesn't appear to fix pgs, even for pgs with 0 objects -- Deleting the pool seems like an appropriate step, but as I am using an xattr within cephfs, which is otherwise on another pool, I am not confident that this approach is safe? -- cephfs currently blocks when attemping to impact every third file in the EC directory. Once I delete the pool, how will I remove the files if even `rm` is blocking?
