[Linux-cluster] mounting problem on RHEL5

[Gordan Bobic]

Not sure, but you'll find that GFS2 is still unstable. The required 
bug-fixes haven't made it to the full release stage yet. RHEL5 stuff is 
not for production use. Use GFS1 instead.

With the latest GFS2 packages on FC7, I can consistently achieve a 
permanent (as in time to reboot the whole cluster) dead-lock within about 
10 seconds of fairly light use.
