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)
Command (m for help):
Command (m for help): m
Command action
a toggle a bootable flag
b edit bsd disklabel
c toggle the dos compatibility flag
d delete a partition
l list known partition types
m print this menu
n add a new partition
o create a new empty DOS partition table
p print the partition table
q quit without saving changes
s create a new empty Sun disklabel
t change a partition's system id
u change display/entry units
v verify the partition table
w write table to disk and exit
x extra functionality (experts only)
Command (m for help):
fdisk /dev/sdd 를 입력하고 n으로 새로운 파티션을 추가합니다.
primary type만 선택하고 나머지는 enter를 입력합니다.

The partition table has been altered!
Calling ioctl() to re-read partition table.
Syncing disks.
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.
