Change server network IP's/Nic's?

[paradox55]

Hi all,

I've manually modified corosync to new IP addresses before but they reverted during the last upgrade.

I'm going to be changing from 1x1gbps network w/2x10gbps nic to 1x2gbps LACP w/1x40Gbps IB per node.

I want the nodes communicating over the 2 Gbps LACP and not IB.

Is there a way to modify this on the nodes without reinstalling?

I am using a separate network. The issue is any changes I made to corosync reverted back on upgrade.

And since I'm replacing the 2x10gbps cards with IB it's going to become unusable if it reverts the changes again.
