[MicroServer G7 N54L] VMWARE에서 HDD 추가 / 마운트 까지...
우선 Power Off 합니다. 그리고
상단 메뉴중 VM -> Setting (CTRL + D) -> ADD -> Hard Disk -> Next -> Next -> Next -> 용량 선택 -> Finish
이렇게 하면 HDD는 추가 한겁니다.
다시 Power On.
그리고 ssh로 접속해서 fdisk -l 을 하면 아래와 같이 나옵니다.
fdisk -l 현재 장착되어 있는 disk를 보여주는 명령어 입니다.

[root@localhost qual]# fdisk /dev/sdb
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
Building a new DOS disklabel with disk identifier 0x996eed0e.
Changes will remain in memory only, until you decide to write them.
After that, of course, the previous content won't be recoverable.
Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)
WARNING: DOS-compatible mode is deprecated. It's strongly recommended to
switch off the mode (command 'c') and change display units to
sectors (command 'u').
Command (m for help):
n => 새로운 파티션을 만듭니다.
- p => 기본 파티션 생성
- e => 확장 파티션 생성
w => 파티션 테이블 설정 저장

Partition number (1-4): 1 => 파티션 번호
First cylinder (1-102, default 1):
Using default value 1 => 하드디스크 용량 시작점.
Last cylinder, +cylinders or +size{K,M,G} (1-102, default 102):
Using default value 102 => 하드디스크 용량 끝. (100메가 하드 디스크 추가)
Command (m for help): w => 파티션 테이블 설정 저장(위에 설정한것 저장)
The partition table has been altered!

마지막에 w를 하고 파티션 설정을 꼭 저장해야 됩니다.
이제 디스크를 추가 했으니 사용하기전에 포멧을 해야합니다.
파일 시스템 포멧 명령어
mkfs -t [파일 시스템] [파티션 경로]
ex) 파일 시스템(ext3/ext4 등등등)
[root@localhost /]# mkfs -t ext4 /dev/sdb1

This filesystem will be automatically checked every 28 mounts or
180 days, whichever comes first. Use tune2fs -c or -i to override.
[root@localhost /]#
파일 시스템 확인 명령어
file -s [파티션 경로]
[root@localhost /]# file -s /dev/sda1
/dev/sda1: Linux rev 1.0 ext4 filesystem data (needs journal recovery) (extents) (large files) (huge files)
[root@localhost /]#
이제 파티션을 추가하고 포멧도 했습니다.
추가한 하드를 쓰려면 이제 마운트(MOUNT) 하면 됩니다.
마운트를 하기위해 디렉토리를 만듭니다.
[root@localhost /]# mkdir Backup
[root@localhost /]# ls
Backup bin boot cgroup dev etc home lib lost+found media misc mnt net opt proc root sbin selinux srv sys tmp usr var
[root@localhost /]#
마운트 명령어
mount [파티션 경로] [마운트 할 경로]
[root@localhost /]# mount -t ext4 /dev/sdb1 /Backup
마운트 정보 확인
df -h
[root@localhost /]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda1 7.8G 3.7G 3.7G 51% /
tmpfs 504M 72K 504M 1% /dev/shm
/dev/sda2 9.8G 24M 9.2G 1% /home
[root@localhost /]# mount /dev/sdb1 /Backup
[root@localhost /]# df -h

/dev/sdb1 95M 1.6M 87M 2% /Backup => mount로 새롭게 추가!!
[root@localhost /]#
이렇게 하면 끝!!!
하지만!! 이건 일시적인것 뿐...
재부팅을 하면 마운트를 다시 해야 합니다.
재시작을 해도 마운트가 풀리지 않도록 fstab에 등록하면 됩니다.
