Ext3和Reiserfs文件系统占用空间的比较

togry@xiaowp:~/disks$ sudo mkfs.ext3 ext3 

mke2fs 1.40.4 (31-Dec-2007)

ext3 is not a block special device.

Proceed anyway? (y,n) y

Filesystem label=

OS type: Linux

Block size=4096 (log=2)

Fragment size=4096 (log=2)

262144 inodes, 524288 blocks

26214 blocks (5.00%) reserved for the super user

First data block=0

Maximum filesystem blocks=536870912

16 block groups

32768 blocks per group, 32768 fragments per group

16384 inodes per group

Superblock backups stored on blocks: 

32768, 98304, 163840, 229376, 294912



Writing inode tables: done 

Creating journal (16384 blocks): done

Writing superblocks and filesystem accounting information: done



This filesystem will be automatically checked every 25 mounts or

180 days, whichever comes first. Use tune2fs -c or -i to override.

A pair of credits:

BigStorage (www.bigstorage.com) contributes to our general fund every month,

and has done so for quite a long time.



Lycos Europe (www.lycos-europe.com) had a support contract with us that

consistently came in just when we would otherwise have missed payroll, and that

they kept doubling every year. Much thanks to them.



reiserfs is not a block special device

Continue (y/n):y

Guessing about desired format.. Kernel 2.6.23.1.build51 is running.

Format 3.6 with standard journal

Count of blocks on the device: 524288

Number of blocks consumed by mkreiserfs formatting process: 8227

Blocksize: 4096

Hash function used to sort names: "r5"

Journal Size 8193 blocks (first block 18)

Journal Max transaction length 1024

inode generation number: 0

UUID: 0d3e668d-77e5-4b5d-a157-a3e937cbc7f4

Initializing journal - 0%....20%....40%....60%....80%....100%

Syncing..ok



Tell your friends to use a kernel based on 2.4.18 or later, and especially not a

kernel based on 2.4.9, when you use reiserFS. Have fun.
