我有1個問題需要請問,我目前有1個4.5TB的硬碟空間,我無法將他全部切成1個EXT3,請問為什麼,以下為我找過網路上的方式試過的結果
此為我的LINUX KERNEL
localhost /root ]# uname -r
2.6.9-78.ELsmp
此為我有3個hd 各hd的大小,第3個sda 即為我的4.5tb空間
localhost /root ]# fdisk -l
Disk /dev/sda: 4499.9 GB, 4499998507008 bytes
255 heads, 63 sectors/track, 68386 cylinders
Units = cylinders of 16065 * 4096 = 65802240 bytes
此為我切割過程的選項
localhost /root ]# fdisk /dev/sda
Note: sector size is 4096 (not 512)
Command (m for help): n
Command action
e extended
p primary partition (1-4)
p
Partition number (1-4): 1
First cylinder (1-68386, default 1):
Using default value 1
Last cylinder or +size or +sizeM or +sizeK (1-68386, default 68386):
Using default value 68386
此為我切好後的的hd大小
localhost /root ]# fdisk -l
Disk /dev/sda: 4499.9 GB, 4499998507008 bytes
255 heads, 63 sectors/track, 68386 cylinders
Units = cylinders of 16065 * 4096 = 65802240 bytes
Device Boot Start End Blocks Id System
/dev/sda1 1 68386 99516812 83 Linux
此為我用第一種方式切出來的空間內容 ,760 block groups 此就是沒有4.5tb的大小
localhost /root ]# mkfs -t ext3 -v /dev/sda1
mke2fs 1.35 (28-Feb-2004)
Filesystem label=
OS type: Linux
Block size=4096 (log=2)
Fragment size=4096 (log=2)
12451840 inodes, 24879203 blocks
1243960 blocks (5.00%) reserved for the super user
First data block=0
Maximum filesystem blocks=25165824
760 block groups
32768 blocks per group, 32768 fragments per group
16384 inodes per group
此為第二種方法: 760 block groups 依舊一樣
localhost /root ]# mke2fs -b 4096 /dev/sda1
760 block groups
已查過kernel 2.4以下都有到4tb ,2.6 以後都有8TB,為何切不出來呢
再有測試過的方法
parted
也是一樣
