Hello,
Maybe somone was fighting with this kind of stuck in ceph already.
This is production cluster, can't/don't want to make wrong steps,
please advice, what to do.
After changing of one failed disk (it was osd-7) on our cluster ceph
didn't recover to HEALTH_OK, it stopped in state:
[root@ceph-mon-01 ~]# ceph -s
cluster:
id: b6f23cff-7279-f4b0-ff91-21fadac95bb5
health: HEALTH_WARN
noout,noscrub,nodeep-scrub flag(s) set
Degraded data redundancy: 24761/45994899 objects degraded (0.054%),
8 pgs degraded, 8 pgs undersized
services:
mon: 3 daemons, quorum ceph-mon-01,ceph-mon-02,ceph-mon-03
mgr: ceph-mon-03(active), standbys: ceph-mon-02, ceph-mon-01
osd: 144 osds: 144 up, 144 in
flags noout,noscrub,nodeep-scrub
rbd-mirror: 3 daemons active
rgw: 6 daemons active
data:
pools: 18 pools, 2176 pgs
objects: 15.33M objects, 49.3TiB
usage: 151TiB used, 252TiB / 403TiB avail
pgs: 24761/45994899 objects degraded (0.054%)
2168 active+clean
8 active+undersized+degraded
io:
client: 435MiB/s rd, 415MiB/s wr, 7.94kop/s rd, 2.96kop/s wr
Restart of OSD didn't helped, changing choose_total_tries from 50 to 100 didn't
help.
I checked one of degraded PG, 10.3c4
[root@ceph-mon-01 ~]# ceph pg dump 2>&1 | grep -w 10.3c4

[root@ceph-mon-01 ~]# ceph pg 10.3c4 query | jq '.["peer_info"][] | {peer:
.peer, last_update:.last_update}'
{
"peer": "0",
"last_update": "36847'71412720"
}
{
"peer": "109",

}
{

}
[root@ceph-mon-01 ~]#
I have checked space taken for this PG on storage nodes:
here is how to check where is particular OSD (on which physical storage node):
[root@ceph-mon-01 ~]# ceph osd status 2>&1 | grep " 9 "
| 9 | stor-a02 | 2063G | 5386G | 52 | 1347k | 53 | 292k |
exists,up |
[root@ceph-mon-01 ~]# ceph osd status 2>&1 | grep " 109 "
| 109 | stor-a01 | 1285G | 4301G | 5 | 31.0k | 6 | 59.2k |
exists,up |
[root@ceph-mon-01 ~]# watch ceph -s
[root@ceph-mon-01 ~]# ceph osd status 2>&1 | grep " 117 "
| 117 | stor-b02 | 1334G | 4252G | 54 | 1216k | 13 | 27.4k |
exists,up |
[root@ceph-mon-01 ~]# ceph osd status 2>&1 | grep " 0 "
| 0 | stor-a01 | 2156G | 5293G | 58 | 387k | 29 | 30.7k |
exists,up |
[root@ceph-mon-01 ~]#
and checking sizes on servers:
stor-a01 (this PG shouldn't be on the same host):
[root@stor-a01 /var/lib/ceph/osd/ceph-0/current]# du -sh 10.3c4_*
2.4G 10.3c4_head
0 10.3c4_TEMP
[root@stor-a01 /var/lib/ceph/osd/ceph-109/current]# du -sh 10.3c4_*
14G 10.3c4_head
0 10.3c4_TEMP
[root@stor-a01 /var/lib/ceph/osd/ceph-109/current]#
stor-a02:
[root@stor-a02 /var/lib/ceph/osd/ceph-9/current]# du -sh 10.3c4_*
14G 10.3c4_head
0 10.3c4_TEMP
[root@stor-a02 /var/lib/ceph/osd/ceph-9/current]#
stor-b02:
[root@stor-b02 /var/lib/ceph/osd/ceph-117/current]# du -sh 10.3c4_*

I'm cross-posting this do devel because maybe there is some known bug
in this particular version of ceph, and You could point some
directions to fix this problem.
