What distro are you using? I've found that:
1) Distros other than RHEL/CentOS can be quirky when it comes to using
RHCS. I've even run into problems on Fedora more than once (not to mention
that FC hasn't shipped GFS1 since FC5 and GFS2 hasn't been deemed
production stable until last month - and we're up to FC10 now).
2) Starting RHCS components using anything except the intended init scripts
tends to cause problems.
3) Source of 99% of problems in the rest of the cases (i.e. not covered by
1) and 2) above) is incorrectly configured fencing.
Does your setup fall under either of the first two categories?
Have you verified beyond doubt that your fencing is configured correctly
and that the fencing script gets verification upon success?
