**마운트할 디렉토리 생성**

mkdir data

**마운트시킬 볼륨 확인**

**파티션 설정**

root@kimbh0132-206594:/# fdisk /dev/vdb 

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 0x3b27ac3f.

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
First sector (2048-104857599, default 2048): 
Last sector, +/-sectors or +/-size{K,M,G,T,P} (2048-104857599, default 104857599): 

Created a new partition 1 of type 'Linux' and of size 50 GiB.

Command (m for help): w
The partition table has been altered.
Calling ioctl() to re-read partition table.

**포멧**

ext4, xfs 등 원하는 형식으로 포멧한다. mkfs 명령어를 사용하여 ext4 형식으로 포멧진행

root@kimbh0132-206594:/# mkfs -t ext4 /dev/vdb1 
mke2fs 1.46.5 (30-Dec-2021)

**마운트 작업**

mount를 진행할 디렉토리를 생성하고 해당 디렉토리에 마운트 진행 /data 에 마운트 진행

root@kimbh0132-206594:/# mount /dev/vdb1 /data

**fstap 등록**

mount한 디스크가 재부팅시에도 자동으로 마운트 되도록 fstap에 등록해둔다 /etc/fstap에 아래와 같이 등록 디스크 이름 or 디스크 UUID / 마운트 포인트 / 파일 시스템 / 마운트 옵션 / 덤프(백업)유무 / fsck 검사 순서

root@kimbh0132-206594:/# cat /etc/fstab
LABEL=cloudimg-rootfs	/	 ext4	discard,errors=remount-ro	0 1
LABEL=UEFI	/boot/efi	vfat	umask=0077	0 1
/dev/vdb1	/data		ext4	defaults	0 0		# 추가

만일 uuid로 마운트를 할것이라면 blkid를 사용하여 UUID 조회 후 /dev/vdb1/ 자리에 넣으면 된다.

root@kimbh0132-206594:/# blkid /dev/vdb1
/dev/vdb1: UUID="d6ee5372-e043-4842-ae80-65174e8c37e2" BLOCK_SIZE="4096" TYPE="ext4" PARTUUID="3b27ac3f-01"
