Yes, that's correct. Once you decide to separate the corosync from the rest
traffic, it will be used only for that purpose.
Storage and live migration traffic will use the other, "primary" network,
unless you decide to separate them too. For example, you can configure the
live migration traffic to use a different network than the storage (man
datacenter.cfg). In regards to zfs storage replication, I'm unsure as I
don't use it. From what I know, that is hardcoded to use the "primary" pve
hostnames for the replication. If that's the case, it will use the
"primary" network for the replication. If the hostnames are configurable,
then you could potentially configure it to use a different network than the
primary.
