We have stopped deepscrubbing a while ago. However, forcing a deepscrub
by doing "ceph pg deep-scrub 6.180" doesn't do anything. The deepscrub
doesn't run at all. Could the deepscrubbing process be stuck elsewhere?

Are you sure its actually getting scrubbed when you issue the scrub?
For example you can issue: "ceph pg <pg_id> query" and look for
"last_deep_scrub_stamp" which will tell you when it was last deep
scrubbed.
Further, in sufficiently recent versions of Ceph (introduced in
14.2.something iirc) setting the flag "nodeep-scrub" will cause all in
flight deep-scrubs to stop immediately. You may have a scheduling
issue where you deep-scrub or repairs arent getting scheduled.
Set the nodeep-scrub flag: "ceph osd set nodeep-scrub" and wait for
all current deep-scrubs to complete then try and manually re-issue the
deep scrub "ceph pg deep-scrub <pg_id>" at this point your scrub
should start near immediately and "rados
list-inconsistent-obj 6.180 --format=json-pretty" should return with
something of value.

Hi,
We currently have a PG stuck in an inconsistent state on an erasure
coded pool. The pool's K and M values are 33 and 3. The command
rados
list-inconsistent-obj 6.180 --format=json-pretty results in the
following error:
No scrub information available for pg 6.180 error 2: (2) No such
file or
directory
Forcing a deep scrub of the pg does not fix this. Doing a ceph pg
repair
6.180 doesn't seem to do anything. Is there a known bug explaining
this
behavior? I am attaching informations regarding the PG in question.
