It does not work for two node cluster (I do not mean necessary
two_node=1). Only one of two nodes may be quorate in this case, which
returns us to possible race condition in case of (unattended) shutdown.
It is the same as with qdevice - everything works as long as we can
ensure qdevice server remains up and reachable until all cluster nodes
