hi,

first of all, please read the documents provided at
http://www.clusterlabs.org/wiki/Documentation

second, i would try to

1. use an ipaddr2 resource for the vip
2. use a cloned group for your resources

then i would either

a. put a specially crafted lsb script doing your reload stuff into the
cloned group (2) and use constraints to start the clone *after* the vip
(1)

or b. put a specially crafted lsb script and your vip (1) into another
group and order: 1.ip before 2 before 1.reload-lsb

maybe there is a much simpler way to handle this use case?
one thing that would come to my mind is something like "run
command/script after resource $action".

cheers,
raoul
