Is this the only PG in this undersized + degraded, or maybe could this be the tailend of a recovery event e.g small % of degraded objects? ceph status output could help as well On Thu, 2 Oct 2025 at 17:53, Sa Pham <saphi070@gmail.com> wrote:

Check dmesg / var/log/messages on the hosts with that PG’s OSDs for errors, and run a `smartctl -a` on each of those OSDs’ drives.

Hi Joshua,
No. OSD is still responding.
# ceph tell osd.130 version { "version": "18.2.7-0-g6b0e988052e", "release": "reef", "release_type": "stable" }
But the primary OSD which includes slow pg (18.773) will respond slower.
detailed as below
# ceph pg dump_stuck degraded PG_STAT STATE UP UP_PRIMARY ACTING ACTING_PRIMARY 18.773 active+undersized+degraded+remapped+backfilling [302,150,138] 302 [130,101] 130
# time ceph tell osd.130 version { "version": "18.2.7-0-g6b0e988052e", "release": "reef", "release_type": "stable" }
real 0m2.113s user 0m0.148s sys 0m0.036s # time ceph tell osd.101 version { "version": "18.2.7-0-g6b0e988052e", "release": "reef", "release_type": "stable" }
real 0m0.192s user 0m0.152s sys 0m0.037s
I don't know why.

could it be an OSD not responding?
I would usually do
ceph tell osd.* version
To test if you can connect with osds

*Hello everyone,*
I’m running a Ceph cluster used as an RGW backend, and I’m facing an issue with one particular placement group (PG).
-
Accessing objects from this PG is *extremely slow*. -
Even running ceph pg <pg_id> takes a very long time. -
The PG is currently *stuck in a degraded state*, so I’m unable to move it to other OSDs.
Current ceph version is reef 18.2.7.
Has anyone encountered a similar issue before or have any suggestions on how to troubleshoot and resolve it?
