Thanks. I most assuredly will, but first I have to run some experiments, to
get a feeling for it.

Happy to help you understand, just keep asking questions. :)
The point can be explained this way;
* If two nodes can work without coordination, you don't need a cluster,
just run your services everywhere. If that is not the case, then you
require coordination. Fencing ensures that a node that
Thanks. This implies that I officially do not understand what it is that
fencing can do for me, in my simple cluster. Back to the drawing board.

Fencing requires some mechanism, outside the nodes themselves, that can
terminate the nodes. Typically, IPMI (iLO, iRMC, RSA, DRAC, etc) is used
for this. Alternatively, switched PDUs are common. If you don't have
these but do have a watchdog timer on your nodes, SBD (storage-based
death) can
