It's not quite like that...
With quorum enabled, STONITH is still a good thing - even without shared
If you want to disable quorum, then you really ought to think about
using STONITH. If you have any kind of shared data in the cluster, then
this is highly recommended. If it's really shared storage (like
FiberChannel), then it's mandatory (whether or not you enable quorum).
So, it's a little softer than that, and the cause and effect is a little
different than you described.
To get it to run when only 1 node is up, then you MUST disable quorum.
