Hello, we run a ceph cluster with the following error which came up suddenly without any maintenance/changes: HEALTH_WARN Reduced data availability: 1 pg stale; Degraded data redundancy: 1 pg undersized The PG in question is PG 25 Output of ceph pg dump_stuck stale: PG_STAT STATE UP UP_PRIMARY ACTING ACTING_PRIMARY 25.0 stale+active+undersized+remapped [] -1 [66,64] 66 Both acting OSDs and the mons+managers were rebooted. All OSDs in the cluster are up. Do you have any idea why 1 PG is stuck?
