[ClusterLabs] I want to have some resource monitored and based on that make an acton. Is it possible?

[Roman Hershkovich]

I have 2 DB servers (master/slave with replica) and 2 APP servers.
2 APP servers managed by pacemaker  (active/passive) , but i want also to
monitor "which DB is master".  I can't use VIP (which could be sticked on
master DB) - it is very limited virtual environment.

Is it possible to create a rule or some other scenario, so in case if
master moved - pacemaker will restart APP (app does not support failover) ?
