I created a pool with no replication and an RBD within that pool. I
mapped the RBD to a machine, formatted it with a file system and dumped
data on it.
Just to see what kind of trouble I can get into, I stopped the OSD the
RBD was using, marked the OSD as out, and reformatted the OSD tree.
When I brought the OSD back up, I now have three stale PGs.
Now I'm trying to clear the stale PGs. I've tried removing the OSD from
the crush maps, the OSD lists etc, without any luck.
Running
ceph pg 3.1 query
ceph pg 3.1 mark_unfound_lost revert
ceph explains it doesn't have a PG 3.1
Running
ceph osd repair osd.1
hangs after pg 2.3e
Running
ceph osd lost 1 --yes-i-really-mean-it
nukes the osd. Rebuilding osd.1 goes fine, but I still have 3 stale PGs.
Any help clearing these stale pages would be appreciated.
Thanks,
-Gaylord
