We prefer Ceph too and we've got our ovirt instance configured in two different ways.1. Openstack Cinder, each VM's disk will have a single volume in ceph with all volumes being under the same pool.
2. Export an RBD via NFS from a gateway machine, this can be a trivially small physical or virtual machine that just exports the NFS share that is pointed at whatever RBD you choose to use.
Not a direct answer to your question, but hopefully it helps.Regards,LoganOn Wed, Jan 25, 2017 at 12:55 PM, Yura Poltoratskiy <yurapoltora@gmail.com> wrote:______________________________Mostly, I want to use rbd like oVirt do with iSCSI storage just to have scalability and high availability (for example, when one storage node failed).Am I crazy? If not, what should I do next: create a file system on top of /dev/foo/bar, say XFS, and add DATA Domain as POSIX compliant? Does it work, I mean does oVirt compatible with not clustered file system in this scenario?Hi,I want to use Ceph with oVirt in some non standard way. The main idea is to map rbd volume to all computes and to get the same block device, say /dev/foo/bar, across all nodes, and then use "POSIX compliant file systems" option to add Storage Domain.
Thanks for advice.PS. Yes, I know about Gluster but want to use Ceph :)_________________
