I just got a 4TB disk and I'm running Ubuntu 12.04. http://www.thegeekstuff.com/2012/08/2tb-gtp-parted/ says you need to partition your disk with GPT if you want to use >2TB (and that you can do this with fdisk/gparted).
However I'm interested in using ZFS. When I tried just running
zpool create tank /dev/sde, I end up with 2TB:
$ sudo zpool list NAME SIZE ALLOC FREE CAP DEDUP HEALTH ALTROOT tank 1.81T 576K 1.81T 0% 1.00x ONLINE - $ sudo parted /dev/sde print Model: WD My Book 1140 (scsi) Disk /dev/sde: 2000GB Sector size (logical/physical): 4096B/4096B Partition Table: gpt Number Start End Size File system Name Flags 1 8389kB 2000GB 2000GB zfs 9 2000GB 2000GB 67.1MB
How should I proceed? Thanks for any hints.
