I recently upgraded from Luminous to Mimic (13.2.6) and now I find
that I have a single pg that is stale and cannot be repaired or
cleaned up. I had to remove several OSDs due to some issues after the
upgrade and now I have this one pg that is in a state that I cannot
get rid of.
Any hints on how to fix this?
$ ceph pg dump_stuck
PG_STAT STATE UP UP_PRIMARY ACTING
ACTING_PRIMARY
54.163 stale+active+undersized+degraded [94,63] 94 [94,63]
94
$ ceph pg 54.163 query
Error ENOENT: i don't have pgid 54.163
Both osd.94 and osd.63 are OK, pool 54 (cephfs_metadata) is a 3-copy
pool, so it looks like the 3rd copy of the pg is missing. The logs
for osd.94 and osd.63 show this when I grep for the missing pg:
