└─>Support for Large Block Devices
In linux kernel since version 2.6.15 (release Date: 2006-01-02)
Enable block devices of size 2TB and larger.
This option is required to support the full capacity of large
(2TB+) block devices, including RAID, disk, Network Block Device,
Logical Volume Manager (LVM) and loopback.
For example, RAID devices are frequently bigger than the capacity
of the largest individual hard drive.
This option is not required if you have individual disk drives
which total 2TB+ and you are not aggregating the capacity into
a large block device (e.g. using RAID or LVM).
If unsure, say N.
