Certainly, fstab didn't shed any light on it

phil at TARDIS[0]<0>:~$ cat /etc/fstab

 but blkid did

phil at TARDIS[0]<0>:~$ sudo blkid
[sudo] password for phil:

phil at TARDIS[0]<0>:~$

The administrator of the server in question has rsynced one of the 4tb
drives to the other, hence the same uuid doh . . . Cheers for the
pointer Rashkae  :)
