Before designing & implementing and shared storage for OpenStack you should think carefully about the workload your shared storage needs to be built for. How many VMs is it servicing? What sort of workloads are they? DBs? Web servers? File servers? etc. Then design according to that spec.

I had much performance issues myself with Windows instances, and I/O demanding instances. Make sure it fits your env. first before deploying it in production

I would take a look into GlusterFS with a distributed, replicated volume. We have been using it for several months now, and it has been stable. Nova will need to have the volume mounted to its instances directory (default /var/lib/nova/instances), and Cinder has direct support for Gluster as of Grizzly I believe.

I have issue with creating shared storage for Openstack. Main idea is to create 100% redundant shared storage from two servers (kind of network RAID from two servers).
I have two identical servers with many disks inside. What solution can any one provide for such schema? I need shared storage for running VMs (so live migration can work) and also for cinder-volumes.
One solution is to install Linux on both servers and use DRBD + OCFS2, any comments on this?
Also I heard about Quadstor software and it can create network RAID and present it via iSCSI.
P.S. Glance uses swift and is setuped on another servers
