Now my ceph -s
, then times out and
contacts a different one.
I have also seen it just be slow if the monitors are processing so many
updates that they're behind, but that's usually on a very unhappy cluster.

On my CEPH cluster, ceph -s return result quite slow.
Sometimes it return result immediately, sometimes i hang few seconds before
return result.
Do you think this problem (ceph -s slow return) only relate to ceph-mon(s)
process? or maybe it relate to ceph-osd(s) too?

I’m not sure if this is the safest way, but it’s worked for me.

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
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
ok

Do you have any suggestion?
Thank you very much indeed!

When using RBD backend for Openstack volume, i can easily surpass 200MB/s.
But when using rbd import command, eg:
# rbd import --pool test Debian.raw volume-Debian-1 --new-format --id
volumes
I only can import at speed ~ 30MB/s
I don't know why rbd import slow? What can i do to improve import
,
that already have millions files?
