The command mkfs.gfs does not work without various parameters passed in:

# mkfs.gfs /dev/shared/testvol
mkfs.gfs: lockproto error: unknown

# mkfs.gfs -p lock_dlm -t Cluster:testvol -j 2 /dev/shared/testvol

As a minimum you need to pass in the above parameters - the locking
protocol, the namespace for it (which in the above example was
"testvol" in the cluster "Cluster") and how many journals.

This is not a bug, it's incorrect invocation of the initial command.
