I’m trying to create an XFS partition >TB. However after formatting I can see only 2TB:

~# parted /dev/sdc
GNU Parted 2.1
Using /dev/sdc
Welcome to GNU Parted! Type ‘help’ to view a list of commands.
(parted) print
Model: DELL MD3000i (scsi)
Disk /dev/sdc: 3608GB
Sector size (logical/physical): 512B/512B
Partition Table: gpt

Number Start End Size File system Name Flags
1 17.4kB 3608GB 3608GB

~# df -h
Filesystem Size Used Available Use% Mounted on
/dev/sdc1 2.0T 70.0M 2.0T 0% /media/iscsi

After formatting parted is no longer able to recognize the partition table:

~# parted /dev/sdc
GNU Parted 2.1
Using /dev/sdc
Welcome to GNU Parted! Type ‘help’ to view a list of commands.
(parted) print
Error: /dev/sdc: unrecognised disk label

The same happens with EXT2/3.
http://xfs.org/index.php/XFS\_FAQ\#Q:*Why\_does\_my*.3E\_2TB\_XFS\_partition\_disappear\_when\_I\_reboot\_.3F shows that it needs CONFIG_LBD=y and CONFIG_EFI_PARTITION=y.
LARGE_BLOCK_DEVICE is enabled while EFI_PARTITION is not.
