As for how to get there, whatever exactly that might look like, I'm also having troubles figuring that out. I figured I would transform the setup described below into one where each host has:
* 2 NICs bonded with LACP for my ovirtmgmt and "main" net * 1 NIC for my 1st storage net * 1 NIC for my 2nd storage net
This is exactly the setup I use. I have run this successfully with CentOS/LIO and FreeNAS iSCSI targets with good performance. In short: - 2 separate, isolated networks for iSCSI with dedicated adapters on hosts and iSCSI target - jumbo frames enabled - no VLANs config needed on hosts, untagged VLANs on switch - do _not_ use LACP, let multipathd handle failovers Same experience as Vinicius: what did _not_ work for me is the iSCSI-Bonding in OVirt. It seems to require that all storage IPs are reachable from all other IPs, which is not the case in every setup. To get multipathing to work I use multipath directly:
I will post a bonnie++ result later. If you need more details please let me know. cu, Uwe
