I'm not sure what's requiring it in your environment. There's no
dependency in the upstream RPM at least.

The pacemaker package does have the crm_master script needed by some
resource agents, so you will need it if you use any of those. (That
script should have been moved to the pacemaker-cli package in 2.1.3,
oops ...)

To make a guest node offline, stop the resource that creates it.
