하드디스크 추가
1. 현재 사용중인 하드디스크 확인(추가전)

2. 추가할 HDD를 HDD확장슬롯에 장착한다.
3. 새로운 HDD를 장착한 후에 서버를 재부팅한다.
4. 재부팅이 끝나고 나면 dmesg란 명령어를 사용하여 장착된 SCSI HDD의 정보를 확인한다.
SCSI device sdb: 71687340 512-byte hdwr sectors (36704 MB)
5. SCSI ID를 확인했다면 이제 fdisk를 실행시켜 파티션을 설정해 준다.
6. 작성된 파티션을 사용하기 위해 파일시스템을 생성한다.
# mke2fs /dev/sdb1 -> for ext2 filesystem
# mke2fs /dev/sdb1 -j -L /data -> for ext3 filesystem
7. 준비된 파티션을 마운트를 시키기 위해 디렉토리를 작성하고 마운트를 시킨다.
# mkdir /data
# mount -t ext2 /dev/sdb1 /data -> for ext2 filesystem
# mount -t ext3 /dev/sdb1 /data -> for ext3 filesystem
8. 부팅시 자동마운트 되게 하기 위한 파일시스템테이블 수정
