For FC disk presented to all nodes in the cluster, why use a filesystem?
use LVM instead,
http://www.ovirt.org/Vdsm_Block_Storage_Domains
The way that oVirt manage storage domains accessed via FC is very smart. There is separate
logical volume for each virtual disk. But I think that logical volume at the same time
could be "touched" only by one host. Is it possible that two host access
read/write the same logical volume and there is no data corruption?
Thanks,
