Centos ext4 mount 방법
1. 시스템 기본정보 확인
[root@test /]# uname -a
Linux test 2.6.18-238.el5PAE #1 SMP Thu Jan 13 17:10:20 EST 2011 i686 i686 i386 GNU/Linux
[root@test /]#
[root@test /]#
2. 디스크의 파티션 확인
[root@test /]#
[root@test /]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda1 9.7G 1.2G 8.1G 13% /
/dev/sda3 201G 188M 190G 1% /home
tmpfs 16G 0 16G 0% /dev/shm
[root@test /]#
3. 물리적인 디스크 확인
; 추가 장착된 /dev/sdb 를 ext4 파일시스템을 만들겠습니다.
[root@test /]#
[root@test /]# fdisk -l

[root@test /]#

4. 새로운 파티션 생성
[root@test /]#
[root@test /]# fdisk /dev/sdb
The number of cylinders for this disk is set to 30334.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other Oss
(e.g., DOS FDISK, OS/2 FDISK)
Command (m for help): n

p primary partition (1-4)

Disk /dev/sdb: 249.5 GB, 249510756352 bytes

Command (m for help): w <- 저장은 꼭! 합시다^^
The partition table has been altered!
Calling ioctl() to re-read partition table.
Syncing disks.

6. ext4 파일시스템을 사용할 수 있게 e4fsprogs 를 설치
[root@test /]#
[root@test /]# yum install e4fsprogs
7. 새로 만든 파티션을 ext4 파일시스템으로 생성
[root@test /]#
[root@test /]# mkfs.ext4 /dev/sdb1
