Doc Text:
.Unreconstructable object errors are not handled properly During a backfill or recovery operation of an erasure coded pool, the unreconstructable object errors were not handled properly. As a consequence, the OSDs terminated unexpectedly with the following message: ---- osd/ReplicatedPG.cc: recover_replicas: object added to missing set for backfill, but is not in recovering, error! ---- With this update, the error handling has been corrected and two new placement group (PG) states have been added: `recover_unfound` and `backfill_unfound`. As a result, the OSD does not terminate unexpectedly, and the PG state indicates that the PG contains unfound objects.
