Hi, gluster is good in scenario when we have many hosts with own storage and we aggregate these pieces it into one shared storage. In this situation data is transferred via Ethernet ore Infiniband. In our scenario we have centralized storage accedes via Fibre Channel. In this situation it would be more efficient when data would be transferred through FC. For FC disk presented to all nodes in the cluster, why use a filesystem? use LVM instead,
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, Piotr
