[linux] 2TB 이상 파티션 잡기

우분투 머신에 하드디스크 추가 및 포맷 후 자동 마운트 설정하기

1. 하드디스크 설치

2. 부팅 후 하드디스크 확인

> sudo fdisk -l
...
Disk /dev/sdb: 512.1 GB, 512110190592 bytes
255 heads, 63 sectors/track, 62260 cylinders, total 1000215216 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x88f488f4

Disk /dev/sdb doesn't contain a valid partition table
...

3. 파티션 생성

> sudo fdisk /dev/sdb
...
Command (m for help): n
Partition type:
   p   primary (0 primary, 0 extended, 4 free)
   e   extended
Select (default p): p
Partition number (1-4, default 1):
Using default value 1
First sector (2048-1000215215, default 2048):
Using default value 2048
Last sector, +sectors or +size{K,M,G} (2048-1000215215, default 1000215215):
Using default value 1000215215

Command (m for help): p

Disk /dev/sdb: 512.1 GB, 512110190592 bytes
255 heads, 63 sectors/track, 62260 cylinders, total 1000215216 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0xe8bf195f

   Device Boot      Start         End      Blocks   Id  System
/dev/sdb1            2048  1000215215   500106584   83  Linux

Command (m for help): w
The partition table has been altered!

4. 포맷

> sudo mkfs.ext4 /dev/sdb1
mke2fs 1.42.9 (4-Feb-2014)
Discarding device blocks: done                            
Filesystem label=
OS type: Linux
...
Writing superblocks and filesystem accounting information: done

5. 마운트

uuid 확인

> sudo blkid
...
/dev/sdb1: UUID="d2eac947-9407-40bb-96cb-acd22e9a57c3" TYPE="ext4"
...

fstab 파일에 파티션 추가

> sudo vi /etc/fstab
UUID=d2eac947-9407-40bb-96cb-acd22e9a57c3 /ssd2 ext4 defaults 0 0

마운트 및 확인

> sudo mkdir /ssd2
> sudo mount -a
> df -h
Filesystem      Size  Used Avail Use% Mounted on
...
/dev/sdb1       470G   70M  446G   1% /ssd2

2TB 이상 파티션 

$ parted /dev/sdb 

# gpt 파티션

(parted) mklabel gpt

# gpt  확인

(parted) print

Partition Table : gpt //확인 완료

(parted) mkpart primary 0 3000GB // 파티션 생성

(parted) print

확인

위에서 포멧하는 과정부터 동일
