[linux] 파티션 분할 하는 방법

 

리눅스도 윈도우 처럼 한개의 하드디스크에서 C: 드라이브 D: 드라이브 처럼 파티션을 나눠서 

 

생성하는 방법이 있고 그 방법이 fdisk라는 명령어를 사용하는 것이며

 

잊어버리지 않기 위해서 작성하였다

 

1. lsblk 상태 확인

 

- 작업해야 하는 파티션 sdb / 680GB

 

root@test_db01:/root> lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sda 8:0 0 60G 0 disk ├─sda1 8:1 0 200M 0 part ├─sda2 8:2 0 51.8G 0 part / └─sda3 8:3 0 8G 0 part [SWAP] sdb 8:16 0 680G 0 disk sdc 8:32 0 256G 0 disk └─sdc1 8:33 0 256G 0 part /var/crash sdd 8:48 0 6T 0 disk └─ 253:0 0 6T 0 lvm /backup01 sde 8:64 0 3T 0 disk └─ 253:2 0 3T 0 lvm /backup02 sdf 8:80 0 3T 0 disk └─ 253:1 0 3T 0 lvm /backup03

 

2. fdisk 파티션 지정

- 100GB, 50GB, 30GB, 500GB 각각 파티션 생성
