Hi,
It's not possible for Corosync 2 and 3 nodes to form a cluster.
Hello,
I have a cluster with two nodes with corosync version 2.4 installed there.
I need to upgrade to corosync version 3.0 without shutting down the cluster.
I thought to do it in this way:
1. Stop HA on the first node, do upgrade to newer version of Linux with
upgrade corosync, change corosync
