Re: [ovirt-users] Multipath iSCSI with several IPs
Once upon a time, James Michels <karma.sometimes.hurts(a)gmail.com> said:
I guess you mean the 'iSCSI multipath' sub-tab under the
'Datacenters' tab.
There you can assign one or more networks to a iSCSI backend. In my opinion
you cannot have more than one interface within the same network segment to
do multipath, as you would have connectivity issues (not sure if ovirt
restricts creating two overlapping networks)
The way I did it on a test 3.6 cluster was to create two networks in
oVirt, "storage1" and "storage2". I assigned both networks to the
hosts, connected to different NICs, and gave each an IP (in the iSCSI
subnet). Then I could set up the iSCSI multipath in the oVirt data
center. This seems weird/wrong, and I'm not sure oVirt actually
configured both NICs in multipath.
