Hi Wiessner,
Actually I created zpool and this is mounted to /dev/sdb and then set a
mountpint to osd.The space showing is 144GB.But the osd's are going down after
rbd image is while running.
Thanks,
Ramu.

thanks for the hint.

One more question, what's the behavior behavior if the disk which
contains every journal crashed? All the OSDs will crash?
Thank you in advance :)

Have you tried qemu 1.1.1? 0.12 seems very old!

Dear list,
are Rados' IoCtx objects able to process multiple asynchronous

to complete, before issuing a following operation?
I.e., can I do the following and expect it to work?

Using RBD storage for Xen VM images / disks is IMHO a very nice fit,
the same way people do with QEMU. This should even allow live

You can't change pg_num of an existing pool, you can only specify this
number when creating the pool.
Support for online pg split/merge is an upcoming feature.
