thank you for this idea, it has improved the situation. Nevertheless,
there are still 2 PGs in recovery_wait. ceph -s gives me:

also the status changed form HEALTH_ERR to HEALTH_WARN. We also did ceph
osd down for all OSDs of the degraded PGs. Do you have any further
suggestions on how to proceed?

I think those osds (1, 11, 21, 32, ...) need a little kick to re-peer
their degraded PGs.
Open a window with `watch ceph -s`, then in another window slowly do
ceph osd down 1
# then wait a minute or so for that osd.1 to re-peer fully.
ceph osd down 11
...
Continue that for each of the osds with stuck requests, or until there
are no more recovery_wait/degraded PGs.
After each `ceph osd down...`, you should expect to see several PGs
re-peer, and then ideally the slow requests will disappear and the
degraded PGs will become active+clean.
If anything else happens, you should stop and let us know.

What's the full ceph status?
Normally recovery_wait just means that the relevant osd's are busy
recovering/backfilling another PG.

Hi,
we have set the PGs to recover and now they are stuck in active+recovery_wait+degraded and instructing them to deep-scrub does not change anything. Hence, the rados report is empty. Is there a way to stop the recovery wait to start the deep-scrub and get the output? I guess the recovery_wait might be caused by missing objects. Do we need to delete them first to get the recovery going?

Hi,
thank you, it worked. The PGs are not incomplete anymore. Still we have
another problem, there are 7 PGs inconsistent and a cpeh pg repair is
not doing anything. I just get "instructing pg 1.5dd on osd.24 to
repair" and nothing happens. Does somebody know how we can get the PGs
to repair?
Regards,
Kevin
Kevin,
I just fixed an inconsistent PG yesterday. You will need to figure out why they are inconsistent. Do these steps and then we can figure out how to proceed.
1. Do a deep-scrub on each PG that is inconsistent. (This may fix some of them)
2. Print out the inconsistent report for each inconsistent PG. `rados list-inconsistent-obj <PG_NUM> --format=json-pretty`
3. You will want to look at the error messages and see if all the shards have the same data.
