③ 디스크에 파티션 생성

hanadb:~# fdisk /dev/sdb

Welcome to fdisk (util-linux 2.33.1).

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 0xed0ff200.

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 (default 값 입력 시 별도 입력 없이 엔터만 쳐도 됨)

Partition number (1-4, default 1): 1 (default 값 입력 시 별도 입력 없이 엔터만 쳐도 됨)

First sector (2048-209715199, default 2048): 2048 (default 값 입력 시 별도 입력 없이 엔터만 쳐도 됨)

Last sector, +/-sectors or +/-size{K,M,G,T,P} (2048-209715199, default 209715199): 209715199 (default 값 입력 시 별도 입력 없이 엔터만 쳐도 됨)

Created a new partition 1 of type 'Linux' and of size 100 GiB.

Command (m for help): w

The partition table has been altered.

Calling ioctl() to re-read partition table.

Syncing disks.

⑤ 위에서 생성한 파티션에 파일시스템 생성 (ext4 파일시스템)

hanadb:~# mkfs.ext4 /dev/sdb1

mke2fs 1.43.8 (1-Jan-2018)

Creating filesystem with 26214144 4k blocks and 6553600 inodes

⑥ 마운트 할 디렉터리 생성 (Optional -> 기존 디렉터리 활용 가능)

hanadb:~# mkdir /hana

hanadb:~# mkdir /hana/shared

⑦ 디렉터리에 파일시스템 마운트

hanadb:~# mount /dev/sdb1 /hana/shared
