I'm about to hit a similar problem. As far as I understand things, with a 2.6 kernel,
if you partition with parted and then mke2fs on those partitions, you should be OK
in terms if the addressability of 5TB. What blocksize does 'dumpe2fs -h /dev/yourpartition'
report? My guess is that it should be 4096 on a 5TB 'device'.

Do you have a screendump of your parted stuff?
