I think I have asked my question not correctly, it is not for the cinder backend, I meant the shared storage for the instances which is shared by the compute nodes. Or can cinder also be used for this? Sorry if I ask stupid questions, OpenStack is still new for me ;-) Regards, Michael > Matt J

If you look at the user survey ( https://www.openstack.org/user-survey/survey-2016-q1/landing ) you can see what the current landscape looks like in terms of deployments. Ceph is by far the most commonly used storage backend for Cinder. On 21 June 2016 at 08:27, Michael Stang wrote: > Hi, > > I

Hi, Hope you have already gone through this document... if not FYI http://docs.openstack.org/ops-guide/arch_storage.html As Saverio said, Ceph is widely adopted solution. For small clouds, we found that NFS is much affordable solution in terms of cost and the complexity. --- Regards, Sampath

Hello Michael, a very widely adopted solution is to use Ceph with rbd volumes. http://docs.openstack.org/liberty/config-reference/content/ceph-rados.html http://docs.ceph.com/docs/master/rbd/rbd-openstack/ you find more options here under Volume drivers: http://docs.openstack.org/liberty/config-

2016-06-21 Thread Michael Stang
Hi, I wonder what is the recommendation for a shared storage for the compute nodes? At the moment we are using an iSCSI device which is served to all compute nodes with multipath, the filesystem is OCFS2. But this makes it a little unflexible in my opinion, because you have to decide how many com
