[Rdo-list] Help on configuring the Openstack setup with SAS Block storage

Dear Members; Im stuck with following question. Appreciate your responses. I have a SAS block storage and needed to configure with Live migration. All controller and computes nodes connected to the block storage through SAS interfaces. In order to enable live migration, If i create a single SAS LUN (volume), and mount it among all node's "/var/lib/nova/instances/" folder, then setup same nova UID GID on all nodes, will be enough for live migration? Or do I have to run any distributed file system like GlusterFS or NFS? Will libvert detect SAS protocol and enable the live migration? Anne. Thanks in advance..
