3TB partition support in Linux

Tue, 31 Jul 2012 00:00:00 +0000

Make a GPT partition:

1
2
3
4
5


parted /dev/sda
mklabel gpt
unit TB
mkpart primary 0 -0
quit

Format with 1% root reservation:

mkfs.ext4 -m1 /dev/sda1

Note: HP Array controller may require firmware update for 3TB disk support.

[root@demo ~]# fdisk -l

/dev/sda3 1306 6527 41942367+ 83 Linux

[root@demo ~]# pvcreate /dev/sda3
[root@demo ~]# vgextend vg_demo /dev/sda3

[root@demo ~]# vgdisplay vg_demo | grep Free
Free PE / Size 10239 / 40.00 GiB

[root@demo ~]# lvextend -L+40.00G /dev/vg_demo/lv_root

[root@demo ~]# resize2fs /dev/vg_demo/lv_root

Note: I wouldn’t do this for any production system as it looks pretty inefficient way to extend volume size.
