Steps
SSD 장착
작업을 위해 machine 전원을 내리고 mvme ssd를 홈에 맞게 장착 후 재부팅.
디스크 장착 확인
방금전에 장착한 465 GiB 의 nvme ssd가 정상적으로 인식 된 것을 확인.
root@latte01:~# sudo fdisk -l
...
Disk /dev/nvme0n1: 465.76 GiB, 500107862016 bytes, 976773168 sectors
Disk model: SHGP31-500GM
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes

현재 사용중인 Disk 확인
위에서 장착한 mvme ssd(`/dev/nvme0n1`)가 아직 마운트 되지 않은 것을 확인할 수 있습니다.
root@latte01:~# df -h

디스크 마운트 진행
위에서 확인한 disk에 파티션을 생성해주기 위해 아래 과정을 진행합니다.
root@latte01:~# sudo fdisk /dev/nvme0n1
Welcome to fdisk (util-linux 2.37.2).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.
Device does not contain a recognized partition table.
Created a new DOS disklabel with disk identifier 0x66336a6e.
Command (m for help): n
Partition type
p primary (0 primary, 0 extended, 4 free)
e extended (container for logical partitions)
Select (default p): p
Partition number (1-4, default 1): 1

The partition table has been altered.
Calling ioctl() to re-read partition table.
Syncing disks.
`Created a new partition 1 of type 'linux' and of size 465.8 GiB.` 문구가 나오고, `w` 까지 입력해야 partition이 제대로 생성됩니다.
디스크 상태 확인한
`fdisk -l` 로 확인해보면 이전과 달리 Device로 잡힌 것을 확인할 수 있습니다.
root@latte01:~# sudo fdisk -l
Disk /dev/nvme0n1: 465.76 GiB, 500107862016 bytes, 976773168 sectors

파티션 포맷
아래 명령어를 통해 다른 File system은 어떤 식으로 포맷되었는지 확인합니다.
root@latte01:~# sudo blkid
/dev/mmcblk2p2: UUID="aa495c97-2344-4d43-a689-b619820a0210" BLOCK_SIZE="4096" TYPE="ext4" PARTUUID="f60e2f86-337d-4890-bfbd-fc6555e075f0"
/dev/loop1: TYPE="squashfs"
/dev/nvme0n1p1: PARTUUID="66336a6e-01"
/dev/mmcblk2p1: UUID="986C-B2FC" BLOCK_SIZE="512" TYPE="vfat" PARTLABEL="EFI System Partition" PARTUUID="995635dd-2919-4051-9388-abfd4e42d81e"
root@latte01:~# df -h
Filesystem Size Used Avail Use% Mounted on
tmpfs 777M 2.1M 775M 1% /run
/dev/mmcblk2p2 57G 39G 16G 72% /
가장 큰 용량을 차지하는 `/dev/mmcblk2p2` 랑 포맷을 맞춰주려고 합니다. 따라서 새로운 disk도 `ext4` 방식으로 포맷하면 될 것 같습니다.
포맷 진행.
root@latte01:~# sudo mkfs.ext4 /dev/nvme0n1

sudo blkid를 입력하면 `ext4로` 포맷된 디스크를 확인할 수 있습니다.
root@latte01:~# sudo blkid
#AS IS

#TO BE

디스크 마운트
디스크를 사용하기위한 폴더를 생성해줍니다.
root@latte01:~# mkdir -p /data1
새로 추가한 disk를 자동마운트 하기위한 정보를 /etc/fstab에 추가합니다.
data1
UUID=482ee0df-9d2d-4959-9026-de7206de5aaf /data1 ext4 defaults 0 0
추가 후
/etc/fstab: static file system information.
#
Use 'blkid' to print the universally unique identifier for a
device; this may be used with UUID= as a more robust way to name devices
that works even if disks are added and removed. See fstab(5).
#

마운트 적용
sudo mount -a
