Dear all,
After some problems I have my ovirt setup running now. But I run into
a new problem with the network configuration.
We have a quad nic with 4 gigabit connections over 2 switches (2X2)
and an active/passive iscsi SAN. The first is connected to switch 1
and the second to switch 2 with a 10Gbe link.
Do you mean you have a host(ovirt node) with a quad nics conneting to
switches? And one SAN connecting to the switch 1 in another side, the
other SAN conecting to switch 2 with a 10Gbe lnk?
You are right, that's our test setup.
Now I would like to use iSCSI multipathing instead of bonding but I
cannot use the same vlan for multiple storage networks and I cannot
assign the same storage network to several nic's.
I could use bonding, but we use 4 links over 2 switches and if I read
everything correctly bonding only works through a single switch.
How do other people achieve this?
The problem I had was that I could't put all the storage nic's in the
same vlan using the ovirt interface.
But I talked to our networking guy and he said just use an untagged vlan
instead of trying to put all the storage nics in the tagged vlan.
I have to brush up my networking knowledge. Thanks for replying though.
And thanks to Ayan too, multipath is now working fine.
Regards, Jorick
