You should try to determine what caused this condition. In all
likelihood you ran out of resources on these nodes (memory is a likely
culprit).

Restarting pacemaker on the nodes where services are no longer running
should bring them back up but you probably want to check that the
nodes are back in a good state before you do so. You can also reboot
the nodes but keep in mind that if you're running ceph and your ceph
mons live on your controllers you can only have one ceph mon offline
at a time. Any less than two active monitors and your storage will go
offline.
