Something else going on here.

I see the device using fdisk;

Disk /dev/sda doesn't contain a valid partition table
You have new mail in /var/spool/mail/root

I then use fdisk to create a partition;

Disk /dev/sda: 774.2 GB, 774207700992 bytes
255 heads, 63 sectors/track, 94125 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/sda1               1       94125   756059031   83  Linux

Looks fine right.

Looking on the net, I can't find anything on gfs_mkfs one single drive so have to make assumptions for now.
Assumptions are, lock mode, cluster name, FS name, journals and device.

#gfs_mkfs -p lock_dlm -t compweb:web -j 8 /dev/sda

Seems to go fine;

Device:                    /dev/sda
Blocksize:                 4096
Filesystem Size:           188738976
Journals:                  8
Resource Groups:           2882
Locking Protocol:          lock_dlm
Lock Table:                compweb:web

Syncing...
All Done

Do an fdisk again;

Disk /dev/sda: 774.2 GB, 774207700992 bytes
255 heads, 63 sectors/track, 94125 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Disk /dev/sda doesn't contain a valid partition table

It's all gone. Guessing I need to gfs_mkfs some other way?

You're going to hit yourself when I say this, but you made the GFS partition on the raw drive (sda rather than sda1), not on a partition. There is nothing wrong with making it on the raw disk, mind you, that's what I always do when using SAN volumes.
