Respawn corosync/pacemaker automatically when it is killed

Question

How to recover Corosync/Pacemaker if it is killed using "kill -9 <corosync-pid>".

Are there any steps needs to be done to bring the corosync service up and running automatically?

Answer 1

Create an upstart script in /etc/init/corosync.conf and /etc/init/pacemaker.conf with respawn option will solve the problem.

Upstart scripts can be found here.
