I faced a similar issue. The PG just would never finish recovery.
Changing
all OSDs in the PG to "osd_op_queue wpq" and then restarting them
serially
ultimately allowed the PG to recover. Seemed to be some issue with
mclock.
Thank you Wes, switchi

22 is more often there than the others. Other operations may be blocked
because of a deep-scrub is not finished yet. I would remove OSD 22, just to
be sure about this: ceph orch osd rm osd.22
If this does not help, just add it again.

No idea what PFA means, but attachments usually don’t make it through on
mailing lists. Paste text instead.

Hi,
You have 67 TB of raw space available. With a replication factor of 3,
which is what you seem to be using, that is ~22 TB usable space under ideal
conditions.
MAX AVAIL column shows the available space, taking into account the raw
space, the replication factor and the CRUSH map, before the fi

Yes. Chapter 8 may help here, but be warned, it’s pretty dense and may confuse
more than help.
The foundation layer of Ceph is RADOS — services including block (RBD), file
(CephFS), and object (RGW) storage are built on top

Now they are increasing , Friday I tried to deep-scrubbing manually and
they have been successfully done , but Monday morning I found that they are
increasing to 37 , is it the best to deep-scrubbing manually while we are
using the cluster? if not what is the best to do in order to address that .
Hi all,
how can radosgw be deployed manually? For Ceph cluster deployment,
there is still (fortunately!) a documented method which works flawlessly
even in Reef:
https://docs.ceph.com/en/latest/install/manual-deployment/#monitor-bootstrapping
But as for radosgw, there is no such descript
