[Pacemaker] question about collocation and mutex

[david.miao]

hello everyone

I have 4 resource agents A B C and D.
A B C should run on the same node, but D should mutex with any of A B C.
The following is my configure, is it correct?

crm configure collocation ABC INFINITY: A B C
crm configure collocation D-mutex-ABC -INFINITY:  D (A B C)

please give my some suggestion? thanks
