(rbd was set to 2, which meant it didn't match, which I'm sure is what
Sage meant. Just correcting the record for those scoring at home.)

All of the stuck pgs are in pool 2. My guess is that that pool is
referncing a broken crush rule.
Your CRUSH map has min and max_size of 3 for all of the rules; it should
be min 1 and max 10. Probably the RBD pool is set to 3 replicas, which
means it matches no existing CRUSH rule and you get no OSDs. You can fix
the CRUSH rules (that is a good idea anyway), or also change the pool 2
(rbd) to 3x replication:
ceph osd pool set rbd size 3

Hi,
I happened to have an incorrect crush map in the start-up of
my system, but even after fixing it manually, the PGs do not
seem to be created properly. Is there any way to trigger the
system to start creating the PGs again ?
Here's my configurations:
ceph.conf: http://pastebin.com/EwwdQrf9
crush map: http://pastebin.com/UYNFvvQx
ceph osd tree: http://pastebin.com/u2Z4Hppn
ceph pg dump: http://pastebin.com/JfE146WJ
FYI, in the first, I had mistakenly osd.0 in all host clauses.
regards,
Yasu
