MicroServer N54L

[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 -l

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

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
mke2fs 1.41.12 (17-May-2010)
Filesystem label=
OS type: Linux
Block size=1024 (log=0)
Fragment size=1024 (log=0)
Stride=0 blocks, Stripe width=0 blocks
26208 inodes, 104432 blocks
5221 blocks (5.00%) reserved for the super user
First data block=1
Maximum filesystem blocks=67371008
13 block groups
8192 blocks per group, 8192 fragments per group
2016 inodes per group
Superblock backups stored on blocks:
        8193, 24577, 40961, 57345, 73729

Writing inode tables: done
Creating journal (4096 blocks): done
Writing superblocks and filesystem accounting information: done

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
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
/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.
