VirtualBox 진행
버추얼박스 관리자 화면
머신 -> 설정
머신설정 화면
저장소 -> 컨트롤러 -> 하드디스크 추가
원하는 경로와 사이즈를 지정 후 만들기 버튼 클릭
data01.vdi로 만들어 주겠습니다
위에 지정해 준 data01.vdi 디스크가 생성된 것이 확인 됩니다
선택 버튼 클릭
해당 머신에 하드디스크가 추가 되었습니다
이제 VM을 기동해 주세요
이후 작업은 O/S(리눅스)에서 진행 합니다

현재 파티션(디스크) 상태 확인
신규로 추가한 디스크는 /dev/sdc 입니다. 디스크에 파티션이 생성되어 있지 않음

신규 추가한 디스크(/dev/sdc)에 파티션 생성
[root@svr1 ~]# fdisk /dev/sdc
Welcome to fdisk (util-linux 2.23.2).
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
Building a new DOS disklabel with disk identifier 0x8d8d55e5.
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):
First sector (2048-20971519, default 2048):
Using default value 2048
Last sector, +sectors or +size{K,M,G} (2048-20971519, default 20971519):
Using default value 20971519
Partition 1 of type Linux and of size 10 GiB is set
Command (m for help): w
The partition table has been altered!

파티션을 만든 후 파일시스템을 마운트 하여 실제 사용하기 위해서는 적절한 형태로 포멧을 진행해줘야 합니다
xfs 타입으로 파일시스템을 생성하겠습니다
