The main mailing list for HA clustering in "Clusterlabs Users": http://clusterlabs.org/mailman/listinfo/users. It's not strictly for any OS, but RHEL/CentOS and SUSE are probably the most common OSes. I might recommend starting with this: https://alteeve.ca/w/History_of_HA_Clustering The Linux-HA project (heartbeat) is long deprecated. The stack to learn is Corosync + Pacemaker. As Nux mentioned, CentOS 7 is the best platform. As you'll see in the History link above, there was a lot of changes that happened between 2008 ~ 2013 era. Learning on any older CentOS means you're learning an old stack, which probably doesn't make sense outside of a few cases. We also have an active IRC channel on #clusterlabs on freenode.net, too. If you stop by, be sure to idle. Folks are from all over so different people are around at different times. That said, people are good about replying to questions when they come around.
