Ah, OK. I've never actually tried to partition a large volume - I
partition the underlying disks and make RAID devices out of them... And
some investigation shows a limit of 2TB for c/f/s disk ...

I just tried parted on a 6TB md device (an MD1000 with 15 x 500GB drives)

bertha:/# parted /dev/md9
GNU Parted 1.6.21 with HFS shrink patch 16

Using /dev/md9
(parted) print
Disk geometry for /dev/md9: 0.000-6193352.750 megabytes
Disk label type: loop
Minor    Start       End     Filesystem  Flags
1          0.000 6193352.750  ext3

so I guess thats ok?

Good luck!
