I had a similar problem in my Redhat Clustering and Storage Management class
the other week. I believe the problem was with a couple of mistakes I made
while playing around in one of the labs. I know once it was because I was
trying to mount the block device instead of the logical volume.

 in my humble opnion, redhat has a log way to provide real enterprise

IIRC, gfs2 is still under development and considered experimental. There's
tons of documentation for production-quality GFS and I imagine once gfs2
gets more mainlined, this will be the case also.
