Personally i discourage the use of the auto restarts/rejoin, if something
wrong happened, better investigate the causes and then enable the failed
failovers shouldnt occour frequently, only if something went really bad: as
far i know, pacemaker and PAF doesnt support any kind of autoheal so it
should a good thing check the causes before.
This is just my opinion and way to work, probably someone more expert can
join the conversation.
