AFAIK pacemaker will not start resources on a node that is scheduled for stonith. Even more: Pacemaker will tra to stop resources on a node scheduled for stonith to start them elsewhere.

We probably need to see logs and configs to understand.

I think it's on by default, so you must have set it to false.
In crm shell it is "configure# property stonith-enabled=...".
