Thanks Lincoln,
indeed, as I said the cluster is recovering, so there are pending ops:
pgs: 21.034% pgs not active
1692310/24980804 objects degraded (6.774%)
5612149/24980804 objects misplaced (22.466%)
458 active+clean
329 active+remapped+backfill_wait
159 activating+remapped
100 active+undersized+degraded+remapped+backfill_wait
58 activating+undersized+degraded+remapped
27 activating
22 active+undersized+degraded+remapped+backfilling
6 active+remapped+backfilling
1 active+recovery_wait+degraded
If it's just a matter to wait for the system to complete the recovery
it's fine, I'll deal with that, but I was wondendering if there is a
more suble problem here.
OK, I'll wait for the recovery to complete and see what happens, thanks.
The blocked MDS might be caused by the 'activating' PGs. Do you have a
warning about too much PGs per OSD? If that is the case,
activating/creating/peering/whatever on the affected OSDs is blocked,
which leads to blocked requests etc.
You can resolve this be increasing the number of allowed PGs per OSD
('mon_max_pg_per_osd'). AFAIK it needs to be set for mon, mgr and osd
instances. There was also been some discussion about this setting on the
mailing list in the last weeks.
