Incidentally I am having similar issues with other PG:
For instance:
pg 0.23 is stuck stale for 302497.994355, current state stale+active+clean, last acting [5,2,4]
when I do:
# ceph pg 0.23 query
or
# ceph pg 5.5 query
It also freezes. I can't seem to see anything unusual in the log files, or in any display of OSDs.

Running ceph health details should list those OSDs. Do you have any?

Unfortunately this won't work because 0.21 is already being creating:~# ceph pg force_create_pg 0.21pg 0.21 already creatingI think, and I am guessing here since I don't know internals that well, that 0.21 started to be created but since its OSD disappear it never finished and it keeps trying.On Sun, Jun 7, 2015 at 12:18 AM, Alex Muntada <alexm@xxxxxxxxx> wrote:Marek Dohojda:One of the Stuck Inactive is 0.21 and here is the output of ceph pg map

If I do
#ceph pg 0.21 query
The command freezes and never returns any output.
I suspect that the problem is that these PGs were created but the OSD that they were initially created under disappeared. So I believe that I should just remove these PGs, but honestly I don’t see how.
Does anybody have any ideas as to what to do next?
ceph pg force_create_pg 0.21We've been playing last week with this same scenario: we stopped on purpose the 3 OSD with the replicas of one PG to find out how it affected to the cluster and we ended up with a stale PG and 400 requests blocked for a long time. After trying several commands to get the cluster back the one that made the difference was force_create_pg and later moving the OSD with blocked requests out of the cluster.Hope that helps,Alex
