디스크 파티션 (2TB 미만)¶

$ sudo 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.

디스크 마운트¶

UUID 확인

$ sudo blkid
/dev/vdb: UUID="071ca808-5e19-4dd1-ac37-2a297e723f34" BLOCK_SIZE="4096" TYPE="ext4"

마운트 디렉토리 생성

$ sudo mkdir /ext

부팅시 자동 마운트 설정

$ sudo vim /etc/fstab
UUID=071ca808-5e19-4dd1-ac37-2a297e723f34 /ext ext4 defaults 0 0

수동 마운트

$ sudo mount -a
