I'm not sure what you're doing differntly (you omitted the FS creation 
command in your previous email), but this works just fine for me:

gfs_mkfs -j 2 -p lock_dlm -t test:root /dev/hdb
mount /mnt/gfs

The fstab line is:
/dev/hdb   /mnt/gfs   gfs   defaults,noatime,nodiratime   0 0

Just tested it on a scratch VM.

I'm assuming you have your cluster.conf configured right and the cman 
service (which provides fenced, groupd, etc.) has started without any 
errors? Again, you haven't posted your cluster.conf so it's impossible 
to tell.

You also haven't specified whether your intention is to use gfs or gfs2. 
They are not the same.

There doesn't seem to be enough in this thread to persuade me that the 
cause of problems isn't user error. :)
