opinions about using monit with drbd, pacemaker and corosync

I 've got a HA cluster and I'm wondering if I should use monit. Pacemaker starts services mysql, apache2, pure-ftp-mysql, dovecote, postfix when the node becomes the master. They can't run all the time because the dirs(files) that they need are not mounted when the node is a slave.
Monit starts/restarts services, so can this couse any problems with the pacemaker (crm) configuration when it wants to promote the other node to master?
Monit will also be managed (start/stop) by pacemaker.
Any advices/opinions about this?

 

I dont know Pacemaker but if it have the same functionality why do you want to use monit?

 

Don't know if it has same functionality that's why I'm asking. But I ended up installing monit.
