Linux 디스크 관리/파일시스템/스왑/논리볼륨 문제

문제)

 

1. VM 디스크 1을 제외한 모든 디스크를 제거 하시오

2. VM 디스크 2 (10G) 를 생성하시오.

3. 다음 사양을 적용 할수 있도록 적당히 파티셔닝 하고 마운트 하시오

- swap 메모리를 500M 추가 하시오(파티셔닝 방법)

- ext4 2G /tmp/test1 에 마운트 되는 파일시스템 생성(논리 아님)

- xfs 1G /tmp/test2 에 마운트 되는 파일시스템 생성(논리 아님)

- 다음과 같은 논리 볼륨을 생성하시오 - 3G, 2G pv -> vgname 인 논리 볼륨그룹 생성

- /vgname/lvname1 1G (ext4 /mnt/lv1)

- /vgname/lvname2 2G (xfs /mnt/lv2)

 

-lvname1 을 1.5G로 확장하시오. 모든 내용은 재부팅 후에도 설정이 유지 되어야 한다.
