[Linux-HA] Corosync 1 - 2
I notice that the network:ha-clustering:Stable repo for CentOS 6 now contains Corosync 2.3.3-1 . I am currently running 1.4.1-17 . Is it safe to just run this update? Are there configuration changes I have to make in order for the new version to work? (If there is a document or wiki page describing how to convert from Corosync 1 to 2, I would be happy to be pointed to it). Thanks, --Greg ___ Linux-HA mailing list Linux-HA@lists.linux-ha.org http://lists.linux-ha.org/mailman/listinfo/linux-ha See also: http://linux-ha.org/ReportingProblems
