Since that particular logical points to a disk that is MSCP served by node1, I
would much prefer that node1 define it because it is responsible for it. This
way, if node2 boots first, when node1 eventually boots, the logical becomes
available to node2 automagically.

Since the clusterwide logicals are made available before systartup_vms, then
the non-existence of a logical means that the node responsible for it isn't up
yet and I must then take action to indefinitely delay the startup of any
software that depends on node1 being up.

The things you learn when one has a power outage... (the only times one gets
to see a reboot in action).
