That's all fine but it heartbeat is supposed to handle starting EVMS and
it doesn't work. It used to work when it was originally setup and the 4
nodes ran find for quite some time but something happened and now after
a recent reboot it will only start on one node at a time. Plus the EVMS
GUI won't start either.

As mentioned; EVMS has been a nightmare from the start. Just getting it
working with heartbeat in the first place was a huge undertaking and
what did it accomplish? We could have done the same thing just using
LVM.

Live and learn I guess.

This client has 4 licensed versions of SLES10 but not a support
agreement.

By the way, when I said "I blame Novell", it was tongue-and-cheek. I
just meant the only reason we tried it was because it was in Novell
"Cool Solutions". I don't blame Novell for EVMS & Heartbeat problems.
