Subject:  Re: [Openstack-operators] Any serious stability and performance
issues on RBD as ephemeral storage ?

Vahric - 

We use Ceph for nova ephemeral as well on thousands of VMs and we love it.
Fast provisioning of VMs, solid, reliable and flexible.   Works great with
live-migration.  The only time we ever have a problem is an OSD is allowed
to get too full.  Never let that happen!
