Hi, I cannot 'halt' my CentOS 6 servers while running corosync+pacemaker. I believe the runlevels used to stop corosync and pacemaker are not in the correct order and create the infinite "Waiting for corosync services to unload..." loop thing. This is my first time with this cluster technology but apparently pacemaker has to be stopped /before/ corosync. Applying the following patch to pacemaker init script fix this issue. # diff -Nu /etc/init.d/pacemaker{.orig,} --- /etc/init.d/pacemaker.orig 2011-09-27 14:08:32.984117731 +0200 +++ /etc/init.d/pacemaker 2011-09-27 14:08:56.125143439 +0200 @@ -6,7 +6,7 @@ # # License: Revised BSD -# chkconfig: - 90 90 +# chkconfig: - 90 75 # description: Pacemaker Cluster Manager # processname: pacemaker # Florian
