Active : Ceph will process requests to the placement group.
Clean : Ceph replicated all objects in the placement group the correct
number of times.
Down : A replica with necessary data is down, so the placement group is
offline.

Degraded : Ceph has not replicated some objects in the placement group the
correct number of times yet.
:: 일부개체가 복제되지 않았다.
Inconsistent : Ceph detects inconsistencies in the one or more replicas of an
object in the placement group (for example objects are wrong size,
objects are missing from one replica after recovery finished, and so
on).

allow recovery.
:: pg내 정보 누락및 복제본이 없는 상태가 감지되었으며 실패한 osd 데몬을 재시작하거나 min_size 를 조정하여 복구를 시도
