[ovirt-users] Hosted engine multipath iscsi

[wodel youchi]

Hi,

I am planning an ovirt hosted-engine installation with two nodes and an
iSCSI SAN for the engine and VMs and NFS for ISO and Export domains, on
another NAS.

The iSCSI SAN have two controllers, each one have two NICs at 1Gb/s, and I
was planning to use a bond manually configured (two NICs) on
hypervisors/nodes, so I'll end up with 4 paths.

- Creating a bond is it a good idea? or do I have to use the node NICs
separately as in the link mentioned earlier?

- If I'll use a bond, will it survive the engine's installation?

- After the engine's installation, the link(s)/path(s) used to connect to
the SAN storage will also be used to connect to the NAS, this will
constitute a storage network, this network will be mandatory so I can't
create an iSCSI bond on top of it. Will the multipath be configured
automatically by the engine's installation on all hypervisors/nodes?

thanks in advance.
