Linux, like other operating systems, has a 2.2TB limitation in the Master Boot Record (MBR). Partitions greater than 2.2TB will need to utilize the GUID Partition Table (GPT) structure.
UEFI systems using GPT partitions is supported by newest 64-bit distributions.
Linux kernel version v2.6.35 or newer is known to support >2TiB disk drives.
Legacy BIOS systems using GPT partitions with a hybrid protective MBR are supported by some Linux distributions. Syslinux v4 adds booting from GPT.
Ubuntu 10.04 (64-bit, code name Lucid Lynx) is reported using a single 3TB data drive.
Check for newer versions of GRUB2, GNU Parted, GNOME Partition Editor (GParted), gdisk and gfdisk which have GPT partitioning support.
