Yes, all monitor intervals have to be different. I don't know
what happened without looking at the logs, but you should set sth
like this:

         op monitor interval="6" role="Master" timeout="30s" \
         op monitor interval="11" role="Master" timeout="30s" OCF_CHECK_LEVEL="10" \

Thanks,

I have a master/slave resource up and running, and when I make the master fail, instead of immediately promoting the slave, it restarts the failed master and re-promotes it back to master. This takes longer than if it would just immediately promote the slave. I can understand it waiting for a DEMOTE action to succeed on the failed master before it promotes the slave, but that is all it should need to do it. Is there any way I can change this behavior? Am I missing some key point in the process?
