ext2、ext3及reiserfs文件系统概述

ext2/3 with 8 KiB blocksize (Systems with 8 KiB pages like Alpha only) 65568 GiB (~ 64 TiB) 32768 GiB (= 32 TiB)

ReiserFS 3.5 2 GiB 16384 GiB (= 16 TiB)

ReiserFS 3.6 (as in Linux 2.4) 1 EiB 16384 GiB (= 16 TiB)

XFS 8 EiB 8 EiB

JFS with 512 Bytes blocksize 8 EiB 512 TiB

JFS with 4KiB blocksize 8 EiB 4 PiB

NFSv2 (client side) 2 GiB 8 EiB

NFSv3 (client side) 8 EiB 8 EiB

Note Kernel Limitations: The table above describes

limitations of the on-disk format. The following kernel limits

exist:

On 32-bit systems with Kernel 2.4.x: The size of a file and a

block device is limited to 2 TiB. By using LVM several block

devices can be combined enabling the handling of larger file

systems.

64-bit systems: The sizes of a filesytem and of a file are

limited by 263 (8 EiB). But there might be hardware

driver limits that do not allow to access such large devices.

Kernel 2.6: For both 32-bit systems with option CONFIG_LBD set

and for 64-bit systems: The size of a file system is limited to

273 (far too much for today). On 32-bit systems

(without CONFIG_LBD set) the size of a file is limited to 2 TiB.
