[linux] PV삭제방법,LV삭제방법,2TB이상 파티션구성방법

OS : Redhat 7.9

 

PV, VG, LV 구성 후에 삭제 후 재구성을 하는 방법이다



처음부터 제대로 하는게 제일 좋지만 만약에 다시 구성을 해야 한다면



자료는 tar로 압축해서 다른 곳으로 옮겨 놓고 작업을 해야한다.



0. 백업 및 umount

$> cp -par /backup01 /oracle_archive/work #작업전 백업



$> umount /backup01 #볼륨 삭제 전에 umount

$> df -h # umount 확인
