[SOLVED] Cluster IP address in HA system.

[Mayank006]

I have 2 networks in my server management and HA. I am creating a cluster which one should I use?

Cheeky answer would be the lower latency / less congested one. If they are equivalent, it really doesn't matter. In fact the cluster syncing supports multiple at once even.

I have used management ips for cluter creation, I am using HA ips for HA network. I was wondering what may happed if I use HA Ips in the cluster formation?

It's your call really. If you are going to use the "HA" network for migrations/replication, then what could happen if it's easy to get saturated by the non-corosync traffic is your quorum getting lost and regained, which in HA scenario might end up having some nodes self-fence, so they would go on rebooting e.g. everytime something started migrating, which you do not really want.
