configname: CONFIG_LBDAF
Linux Kernel Configuration
└─>Enable the block layer
└─>Support for large (2TB+) block devices and files
In linux kernel since version 2.6.31 (release Date: 2009-09-09)
Enable block devices or files 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.
This option also enables support for single files larger than
2TB.
The ext4 filesystem requires that this feature be enabled in
order to support filesystems that have the huge_file feature
enabled. Otherwise, it will refuse to mount in the read-write
mode any filesystems that use the huge_file feature, which is
enabled by default by mke2fs.ext4.
The GFS2 filesystem also requires this feature.
If unsure, say Y.
