Hi all
I have a Ceph cluster (Nautilus 14.2.11) with 3 Ceph nodes.
A crash happened and all 3 Ceph nodes went down.
One (1) PG turned "active+clean+inconsistent", I tried to repair it. After the
repair, now shows "active+clean+inconsistent+failed_repair" for the PG in the
question and cannot bring the cluster to "active+clean".
How do I rescue the cluster? Is this a false positive?
Here are the detail:
All three Ceph nodes run ceph-mon, ceph-mgr, ceph-osd and ceph-mds.
1. ceph -s
health: HEALTH_ERR 3 scrub errors Possible data damage: 1
pg inconsistent
pgs: 191 active+clean 1 active+clean+inconsistent
2. ceph health detailHEALTH_ERR 3 scrub errors; Possible data damage: 1 pg

"inconsistents": []}
8. ceph pg 3.b list_unfound { "num_missing": 0, "num_unfound": 0,
"objects": [], "more": false}
Appreciate your help.
ThanksSagara
