Re: FSM corruption and standby servers

If or when I get a successfull installation containing the abovementioned
components in 24/7 operation I
will try to contribute to your documentation. Before that I would
appreciate if one of you kind people
would review the solution. The cluster(OS) design I intend to get rewieved
by Redhat to be sure of zero faulttolerant.

Thanks.
