CentOS 5.5
DRBD 8.3.8
Corosync 1.2.5
Pacemaker 1.0.9
Whenever I use DRBD MC to manage the configuration above, I run into stability problems with the cluster. Here is some of the behavior I have observed:
1. Corosync crash across cluster members. When I try to restart corosync I receive a Bus Error and cannot restart it until I reboot the system.
2. Frequent disconnects and reconnects across the cluster members.
3. Unresponsive cluster. Whenver I try to manage the cluster in DRBD MC commands are ignored.
When I manage the cluster from the command line without using the MC everything works fine. Also if I use the following stack versions everything seems to be fine:
CentOS 5.5
DRBD 8.3.8
Corosync 1.2.0
Pacemaker 1.0.8
It seems to be an issue with DRBD MC and the latest Pacemaker and Corosync versions.
Thank you,
Jamie Sammons
