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!

I'd say using Ceph for ephemeral disks is the most common deployment pattern, at DataCentred we've been using it for years. It's rock solid and has been for several releases. There were some edge case issues around resizing and snapshotting, but I think that's all been fixed in the last couple of iterations.

We've been using it and recommending it for years. It solves many many problems with a running cloud and there have been very few issues. Pay close attention when upgrading versions of CEPH and do things in the right order and you will be fine!

Hello All,

I would like to use ephemeral disks with ceph instead of on nova compute node. I saw that there is an option to configure it but find many different bugs and reports for its not working , not stable , no success at the instance creation time.
Anybody In this list use ceph as an ephemeral storage without any problem ?
Could you pls share your experiences pls ?

Regards
VM
