1. HDD 추가
VBox HDD 2개 추가
2. 파티션 분할
# fdisk
fdisk: Usage:
fdisk [options] <disk> change partition table
fdisk [options] -l <disk> list partition table(s)
fdisk -s <partition> give partition size(s) in blocks
Options:
-b <size> sector size (512, 1024, 2048 or 4096)
-c switch off DOS-compatible mode
-h print help
-u <size> give sizes in sectors instead of cylinders
-v print version
-C <number> specify the number of cylinders
-H <number> specify the number of heads
-S <number> specify the number of sectors per track

fdisk -l 로 다시 확인하면 두 개의 파티션이 분할된 부분이 보여진다.

3. 파일시스템 생성
- mke2fs -j 옵션 : ext3 파일시스템으로 포맷)
- mkfs.ext4 : ext4 파일시스템으로 포맷)
# mkfs.ext4 /dev/sdb1
:
:(생략)
# mkfs.ext4 /dev/sdb2
:
:(생략)
4. 마운트 (-t 옵션 : 파일시스템의 종류를 선택)
--------------------------------------------------
ex) mount --help
-t vfat , -t ext3 , -t iso9660
-o ro
# mount -t iso9660 -o ro /dev/cdrom /mnt/cdrom
# mount -t ext4 /dev/sdb1 /home/data
--------------------------------------------------
# mkdir /mnt/hdd1 /mnt/hdd2
# ls /mnt
hdd1 hdd2
# mount /dev/sdb1 /mnt/hdd1
# mount /dev/sdb2 /mnt/hdd2
5. 마운트 확인
# mount
/dev/sda2 on / type ext4 (rw)
proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)
devpts on /dev/pts type devpts (rw,gid=5,mode=620)
tmpfs on /dev/shm type tmpfs (rw,rootcontext="system_u:object_r:tmpfs_t:s0")
/dev/sda1 on /boot type ext4 (rw)
/dev/sda7 on /home type ext4 (rw)
/dev/sda5 on /tmp type ext4 (rw)
/dev/sda3 on /usr type ext4 (rw)
/dev/sda6 on /var type ext4 (rw)
none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)
/dev/sdb1 on /mnt/hdd1 type ext4 (rw) <--
/dev/sdb2 on /mnt/hdd2 type ext4 (rw) <--
# df
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/sda2 2958224 278024 2526600 10% /
tmpfs 510024 0 510024 0% /dev/shm
/dev/sda1 95054 31801 58133 36% /boot
/dev/sda7 194241 1552 182449 1% /home
/dev/sda5 487652 2322 459730 1% /tmp
/dev/sda3 1983056 398452 1482204 22% /usr
/dev/sda6 487652 25438 436614 6% /var
/dev/sdb1 4003828 8216 3785564 1% /mnt/hdd1 <--
/dev/sdb2 4053668 8184 3836240 1% /mnt/hdd2 <--
6. 자동 마운트 설정 (여기서는 방법2를 이용한다)
방법1 : /etc/rc.local 파일에 mount 정보를 넣으면 된다.
방법2 : /etc/fstab 파일에 mount 정보를 넣으면 된다.
# vi /etc/fstab
-- /etc/fstab --
:
:(생략)
proc /proc proc defaults 0 0
/dev/sdb1 /mnt/hdd1 ext4 defaults 1 2
/dev/sdb2 /mnt/hdd2 ext4 defaults 1 2
-- /etc/fstab --
리부팅 후 에 자동으로 마운트가 되는 확인한다.
로그인 후 df 로 확인했을 때 /mnt/hdd1, /mnt/hdd2 가 올라오면 성공
# reboot
로그인 후
# df
