There is NO working configuration for the quorum server.
The above line does not work.
It will only defer to the quorum server in case majority is lost. If the
quorum server than grants quorum, while the other side still has
majority, both sides will have quorum.
(The above line "works" for the very special case of two nodes only, but
that's luck, not design.)
Just using the quorumd plugin does not work either.
DO NOT USE THE QUORUM SERVER.
It is broken. Badly designed. Not integrated with STONITH. Not thought
out. Etc. Etc.
Yes, the quorum server grants quorum to one of its clients. That works.
But that is only like 40% of the whole answer. You DO NOT want to use
it.
And if you do, test it. As in, really test it and work through the
scenarios. You'll find out for yourself.
You have been warned.
