리눅스(Ubuntu) 하드 디스크 추가하고 mount하기

수집되고 있는 데이터들이 많아져서 1TB 디스크 두 개를 추가하였습니다. 

fdisk -l 로 추가된 디스크를 확인합니다. 

# fdisk -l

Disk /dev/sde doesn't contain a valid partition table

새로운 디스크 2개의 경로를 확인합니다. 

/dev/sdd 와 /dev/sde 로 잡혀있습니다. 

fdisk /dev/sdd 을 입력해서 파티션 설정을 합니다. 

m을 입력하면 명령어 리스트를 볼 수 있습니다. 

# fdisk /dev/sdd

Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel

Building a new DOS disklabel with disk identifier 0x5bb28c04.

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)

fdisk -l 명령어를 사용하여 단일 파티션이 구성된 것을 확인했습니다. 

# fdisk -l /dev/sdd

이제 새로운 디스크를 포맷해야 합니다. 

blkid 명령어를 사용하면 해당 디스크의 파일시스템 타입을 알 수 있습니다. 

ext4로 나타나서 mkfs.ext4를 사용하여 ext4타입으로 포맷을 합니다. 

# mkfs.ext4 /dev/sdd

mke2fs 1.42.9 (4-Feb-2014)

/dev/sdd is entire device, not just one partition!

Proceed anyway? (y,n) y

포맷이 완료되면 이제 mount를 할 준비가 다 되었습니다. 

이제 새로운 디스크를 mount할 새로운 폴더를 생성합니다. 

root 디렉토리로 이동하여 data 디렉토리를 생성합니다. 

그리고 mount 명령어를 사용하여 mount를 완료합니다. 

df -h를 사용하여 mount 정보를 확인합니다. 

새로운 하드 디스크가 제대로 마운트 된 것이 확인 되었습니다. 

# cd/

#mkdir data

# mount -t ext4 /dev/sdd /data

# df -h
