fuser -contains a filesystem in use 에러 발생시

Linux 2025. 3. 4. 13:57 posted by CecilDeSK

lvm으로 묶여있던 HDD를 분리하기 위해 작업하던중 Logical volume rl/lvhome contains a filesystem in use.

~ contains a filesystem in use. 에러가 발생했다.

해당에러가 발생하면서 umount가 되지 않는다. 위작업은 lvremove 명령 실행시 발생했다.

fuser 명령을 이용해 kill 하고 진행하도록 한다.

root@debian40:/# lvremove /dev/rl/lvhome 
  Logical volume rl/lvhome contains a filesystem in use.

원래 하드드라이브가 레이드가 구성되어있던것이라던가 lvm를 설정중이던가 하면 파일시스템정보 파티션테이블 서명 등 메타데이터가 남아있을수 있어 삭제하는 작업이 필요하다.

wipefs 명령을 사용한다.

IIS 8(Windows Server 2012)이상에서 에디트플러스 등 파일수정권한이 없다고 나올때 또는 RaiDrive 등 접근권한이 없다고 나올때

Windows 2024. 12. 10. 15:52 posted by CecilDeSK

IIS 8이상 버전에서 권한이나 설정등은 이상없는데 550 access is denied 에러메세지가 나오는 경우 확인해볼사항 입니다.
IIS 8이상에서 보안 설정이 강화되어 발생할수있는데

공유해줄 해당 폴더에서 ftp 사용자를 별도로 추가해서 수정권한등을 부여해 주면 됩니다.
사용자가 없을경우는 사용자를 미리 추가해주어야 합니다.
