Re: [Linux-cluster] <crit> #12: RG xxcluster failed to stop; intervention required



yeah, I just had this same problem.  the stock apache init script
returns 1 if you (or the RGmanager) passes it 'stop' when apache's not
running.  the rgmanager attempts to stop the service before starting it
(to be sure it's not running), gets this "error" result, and gives up.
So ... you either have to start apache manually before trying to
reenable it in the cluster, or fix the init script so that it returns 0
(ideally, it should return 0 if you try to stop and it's not running,
but non-zero if you try to stop and it IS running and it fails to stop
for some reason ... but I didn't put that much effort into it ;-)
