Thanks for the information Mike, I would initially test with GlusterFS.

We run GFS2 for our shared instances volume and it has worked very well
for us. We leverage CLVM and fiber connected SAN LUNs on the backend in
order to do that. It's great for live migrations, etc.
I'm told that GFS2 performance degrades significantly once you mount the
filesystem on more than about 16 nodes. We are planning on moving to
GlusterFS or Ceph in the future for a couple of reasons:
- Ceph and Cluster scale-out more linearly
- We want to use more commodity-type hardware in remote data centers
- We don't any want cluster/quorum related issues to take down the shared
storage

Thanks for the reply Robert;
Does GFS is stable now ? Are there Openstack production setups runs with
GFS?

We have four servers and one SAS data store for the openstack
deployment. All servers have SAS
interfaces. We are going to put one controller node and 3 compute
nodes. We need to run the system with
live migration enabled.
Is there are other options available to use the Compute nodes SAS
interfaces too but live migration needed also
enabled.
The only way to directly access the same data on the SAS data store would
be by running a clustered filesystem. (e.g. GFS)
Clustered filesystems are quite a bit more complex then regular
filesystems so I'm not sure if that would be the preferred route though.
