So much for GFS2 being stable enough for production use in RHEL 5.1 ...
I'm still puzzled by the rush to get GFS2 out. GFS1 works. It's stable. It 
gets the job done. Having GFS2 available in RHEL5.x before it's stable 
just ends up annoying people who try it and giving RHEL a bad name. Put it 
in RHEL6 when it's been through the full testing cycle. Otherwise all it 
does is diminish the only advantage of RHEL over Fedora.

Just MHO...
