[Pacemaker] 4 servers; different resources on different servers?

[Tomasz Chmielewski]

I want to build a cluster of 4 servers (servers A, B, C, D), with
different resources on them (mysql, webserver):

webservers: A B C D
mysql:      A B


Is there a way to make Pacemaker/heartbeat to let assign MySQL IP *only*
to servers A or B? Webserver IPs should be assigned to all servers (A,
B, C, D).

I.e. if server A dies, I want to be sure MySQL IP is assigned to server
B, but not C or D.
