On my CEPH cluster, "ceph -s" return result quite slow.
Sometimes it return result immediately, sometimes i hang few seconds before

I'm using the latest Giant and have the same issue. When i increase PG_num
of a pool from 2048 to 2148, my VMs is still ok. When i increase from 2148
to 2400, some VMs die (Qemu-kvm process die).
My physical servers (host VMs) running kernel 3.13 and use librbd.
I think it's a bug in librbd with cr

My ceph cluster have a pg in state "incomplete" and i can not query them
any more.
*# ceph pg 6.9d8 query* (hang forever)
All my volumes may be lost data because of this PG.
# ceph pg dump_stuck inactive

Hi folks, some volumes in my ceph cluster have problem and I can NOT delete
it by rbd command. When i show info or try to delete it, rbd comand crash.
Command i used:
*# rbd -p volumes info volume-e110b0a5-5116-46f2-99c7-84bb546f15c2# rbd -p
volumes rm volume-e110b0a5-5116-46f2-99c7-84bb546f15c2*

output here.

I only can import at speed ~ 30MB/s

I have a CEPH cluster with 9 nodes (6 data nodes & 3 mon/mds nodes)
And i setup 4 separate nodes to test performance of Rados-GW:
- 2 node run Rados-GW
- 2 node run multi-process put file to [multi] Rados-GW
Result:
a) When i use 1 RadosGW node & 1 upload-node, speed upload = 50MB/s
