yap and that´s my issue.
stonith is very powerfull but how can the cluster handle hardware
failure?
by connecting to the switch that supplies power to said hardware
exactly the reason devices like fence_virsh and external/ssh are not
considered reliable.
are both these VMs running on the same physical hardware?

you dont need the host map if the name and value (name:value) are the same

I think your 2nd node can't make quorum, there is some special config
for 2 node cluster to allow nodes to make quorum with 1 vote..

Subject: [Pacemaker] crm resource doesn´t move after hardware crash
hi,
i have a hardware crash in a two-node drbd cluster.
the active node has a hardware failure is actual down.
i am wondering that my 2nd doesn´t migrate/move the resource.
the 2nd node want´s to fence the device but that´s not possible (it´s
down)
how can i enable the services on the last good node?
and how can i optimize my config to handle that kind of error?
