우분투에 HDD 추가하기

1.현재 파티션 정보를 확인한다.

sayit@ubuntu:~$ df -h
Filesystem      Size  Used Avail Use% Mounted on
udev            478M     0  478M   0% /dev
tmpfs            98M  4.9M   93M   5% /run
/dev/sda1        19G  1.2G   17G   7% /
tmpfs           489M     0  489M   0% /dev/shm
tmpfs           5.0M     0  5.0M   0% /run/lock
tmpfs           489M     0  489M   0% /sys/fs/cgroup
tmpfs            98M     0   98M   0% /run/user/1000

2.HDD가 정상적으로 추가되었는지 확인한다.

sayit@ubuntu:~$ sudo fdisk -l

5.포맷

sayit@ubuntu:/sbin$ sudo mkfs.ext4 /dev/sdb1

6.HDD를 마운트 하기위한 UUID 확인

sayit@ubuntu:/sbin$ ls -alF /dev/disk/by-uuid/
total 0
drwxr-xr-x 2 root root 100 Apr 21 00:09 ./
drwxr-xr-x 5 root root 100 Apr 20 23:59 ../
lrwxrwxrwx 1 root root  10 Apr 20 23:59 d0652bd6-9c7f-49d2-8cf8-103dee620427 -> ../../sda1
lrwxrwxrwx 1 root root  10 Apr 20 23:59 e5ec694c-4d6a-44e2-8f78-ec027b45e64d -> ../../sda5
lrwxrwxrwx 1 root root  10 Apr 21 00:09 ec60583a-d84e-40f6-bcb1-16a8c1cc3224 -> ../../sdb1

7.마운트
HDD 파티션 나누고 포맷도 했지만, 지금은 사용할 수 없다. 마운트를 해야한다.

마운트할 디렉토리를 만든다.

sayit@ubuntu:/sbin$ cd /
sayit@ubuntu:/$ sudo mkdir zetacore
sayit@ubuntu:/$ sudo mkdir /zetacore/cube

매번 부팅시마다 자동으로 마운트가 되도록 다음과 같이 설정한다.

sudo vi /etc/fstab

...
UUID=ec60583a-d84e-40f6-bcb1-16a8c1cc3224 /zetacore/cube               ext4    errors=remount-ro 0       1


부팅하지 않아도 바로 적용할 수 있다.

sayit@ubuntu:/zetacore/cube$ sudo mount -a

8.확인
