Re: Ceph + Nova
JuanFra,
I do use cephfs in production, but not for the /var/lib/instances directory. I do host the openstack database and the openstack configuration files on it for an HA cloud controller cluster, but I am probably crazier than most people, and I have a very small deployment. I currently have not had any problems with it, but due to the size of my cloud, I can afford to be very hands-on with it.
The reason I have not hosted the /var/lib/instances directory is due to the fact that the data gets a lot more activity than my small database does. Instead, I prefer to perform block migrations rather than live ones until cephfs becomes more stable.

Subject: Re: [Openstack] Ceph + Nova
Hi,
I don't think it's the best place to ask your question since it's not
directly related to OpenStack but more about Ceph. I just put in c/c
the ceph ML. Anyway, CephFS is not ready yet for production but I
heard that some people use it. People from Inktank (the company behind
Ceph) don't recommend it, AFAIR they expect something more production
ready for Q2 2013. You can use it (I did, for testing purpose) but
it's at your own risk.
Beside of this RBD and RADOS are robust and stable now, so you can go
with the Cinder and Glance integration without any problems.
Cheers!
