Hi All
I'm looking to add a new host to my oVirt lab installation.
I'm going to share out some LVs from a separate box over iSCSI and will
hook the new host up to that.
I have 2 NICs on the storage host and 2 NICs on the new Ovirt host to
dedicate to the iSCSI traffic.
I also have 2 separate switches so I'm looking for redundancy here. Both
iSCSI host and oVirt host plugged into both switches.
If this was non-iSCSI traffic and without oVirt I would create bonded
interfaces in active-backup mode and layer the VLANs on top of that.
But for iSCSI traffic without oVirt involved I wouldn't bother with a
bond and just use multipath.
From scanning the oVirt docs it looks like there is an option to have
oVirt configure iSCSI multipathing.
So what's the best/most-supported option for oVirt?
Manually create active-backup bonds so oVirt just sees a single storage
link between host and storage?
Or leave them as separate interfaces on each side and use oVirt's
multipath/bonding?
Also I quite like the idea of using IPv6 for the iSCSI VLAN, purely down
to the fact I could use link-local addressing and not have to worry
about setting up static IPv4 addresses or DHCP. Is IPv6 iSCSI supported
by oVirt?
Thanks, Ben
