Cluster Node to Node IP

[Ivan Gonzalez]

I like to swap from public ip to private ip for the Cluster of nodes

for months i been waiting to swap that, both have public and private but noticed that cluster is node to node is using the public ip..

can i change, from public to private on all nodes and restart cluster and not restart node.
bindnetaddr:


node can not be restarted, they highly active 24hrs

First, what exactly do you mean with "cluster node address", the corosync address, the "node" address which then is used by default for migration traffic, etc., as those are different ones.

Both are dooable, but I'd try it out first before doctoring on production nodes if you never have done this and are not too comfortable with corosync (if it's that address).
You could setup a nested PVE setup in VMs, cluster them and try a switch of the corosync/cluster IP there until you get it right.
