CONFIG_LBD: Support for Large Block Devices

General informations

The Linux kernel configuration item CONFIG_LBD has multiple definitions:

Support for Large Block Devices found in block/Kconfig

The configuration item CONFIG_LBD:

Help text

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.

Support for Large Block Devices found in drivers/block/Kconfig

The configuration item CONFIG_LBD:

Help text

Say Y here if you want to attach large (bigger than 2TB) discs to your machine, or if you want to have a raid or loopback device bigger than 2TB. Otherwise say N.

Support for large block devices and files found in block/Kconfig

The configuration item CONFIG_LBD:

Help text

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 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 N.
