1. 개요

  • LVM에 대한 이해는 추후 포스팅하도록 하겠습니다.
  • 이 포스트는 jfs2 타입의 파일시스템을 명령어 기반으로 간편하게 생성하는 데, 기반을 둡니다.

2. JFS2타입의 1G 파일시스템 생성.

1) 파일시스템 생성단계  

  ▪ Volume Group 생성 (Physical Volume의 Group)

    ·  ex) hdisk1, hdisk2

  ▪  Volume Group 내의 Logical Volume 생성

  ▪  Logical Volume과 파일시스템 연결작업(Mount Point 생성)

 

2) VG 생성 명령어

  ▪  #mkvg -S -s 256 -y testvg hdisk1 hdisk2

    ·  -S : Scalable Volume group으로 생성.

    ·  -s : PP size를 256으로 지정

    ·  -y : Volume group 이름

    ·  hdisk1 hdisk2 : Volume group에 종족될 Physical Volume.  

      ※ 아래의 명령어는 "testvg" 볼륨그룹 생성정보.

2) LV 생성 명령어

  ▪  #mklv -t jfs2 -y test_lv testvg 1G

    ·  -t : 파일시스템 타입

    ·  -y : LV name

    ·  testvg : Volume group 이름

    ·  1G : 생성하고자 하는 용량

      ※ 아래의 명령어는 "test_lv" 생성 후, LV 생성정보.

NIM 서버에서 Non-rootvg Restore

NIM/NIM Backup_Restore2021. 3. 14. 22:04
반응형

1. 고려사항

  • NIM Master에 복구하고자 하는 클라이언트의 "savevg" Resource가 있는지 확인필요.
  • NIM Server / Client 간의 네트워크 통신이 정상적인 상황인지 확인필요. (Network check)
  • NIM Server / Client 간의 NFS 통신이 정상적인지 확인필요. (NFS Communication Check)
  • NIM Server 에서 Client로 nimpush 프로세스를 이용하여, 복구가 진행된다.
  • 일반적인 restvg 복구절차와 동일하게, 복구하는 과정에서 "VG 생성 > LV 생성 > FS 생성 > 데이터복구" 가 발생하며, 복구한 VG 내의 파일시스템은 자동 마운트된다.

2. 확인

  1) 복구하고자 하는 클라이언트 Machine 상태확인.

   Cstate_result   = success
  
  • Cstate 가 ready 상태이므로, NIM Remote opreation이 가능한 상태. 

2) 기존에 savevg로 백업받아놓은 Resource가 있는지 확인.

3. 복구

1. 고려사항

  • 이 문서는 기존에 NIM Server / Client 구성이 되어있다는 가정하에 작성된 문서입니다.
  • NIM Master에 백업하고자하는 Client의 Machine 등록 및 네트워크 통신이 정상적인 상태라는 가정.

2. NIM 서버를 이용한 Non-rootvg 백업 - SMIT

  • NIM Machine 등록확인 및 상태체크
