안쓰는 VG02 로 VG 사용


3. 스크립트 생성
/tmp/lvm/pvcreate_vg02.sh 생성
pvcreate -f /dev/rdsk/c0t11d4

4. VG 만들다 잘못됐을경우
# vgchange -a n /dev/vg02
# vgexport vg02
로 하면 /dev/vg02 와 vg02 가 삭제됨

# mkdir /dev/vg02
# mknod /dev/vg02/group c 64 0x020000
으로 만들어주면 됨


5. vgcreate 스크립트 생성
-p 는 PV 갯수라서 255개로 넉넉히 줌 (기본값이 16)
-s 는 PE 사이즈라서 32MB 로 만듬 (기본값이 4)

# vgcreate_vg02.sh 생성
hostname :/tmp/lvm] cat vgcreate_vg02.sh
vgcreate -p 255 -s 32 vg02 \

Volume group "/dev/vg02" has been successfully created.
Volume Group configuration for /dev/vg02 has been saved in /etc/lvmconf/vg02.conf
위와 같이 뜨면 성공


6. LV 생성
PE Size * Total PE 를 곱하면 220096 사이즈가 나옴

hostname :/tmp/lvm] lvcreate -L 220096 vg02
Logical volume "/dev/vg02/lvol1" has been successfully created with
character device "/dev/vg02/rlvol1".
Logical volume "/dev/vg02/lvol1" has been successfully extended.
Volume Group configuration for /dev/vg02 has been saved in /etc/lvmconf/vg02.conf


7. filesystem 생성
-F 는 vxfs 를 사용하고 -o largefiles 를 넣어줘야 대용량 파일을 핸들링할 수 있음

hostname :/] newfs -F vxfs -o largefiles /dev/vg02/rlvol1
version 5 layout
225378304 sectors, 225378304 blocks of size 1024, log size 16384 blocks
unlimited inodes, largefiles supported
225378304 data blocks, 225305112 free data blocks
6878 allocation units of 32768 blocks, 32768 data blocks


8. fstab 수저
/etc/fstab 에 추가
/dev/vg02/lvol1 /home2 vxfs delaylog 0 2


9. 부팅시 자동으로 마운트 되게 하기 (클러스터 볼륨일 경우 기본값이 0으로 Disable 임)
/etc/lvmrc 에
AUTO_VG_ACTIVATE=1


10. 확인
cmviewcl 확인

# cmhaltnode hostname
으로 node 를 죽인후 리부팅
# reboot

마운트해서 제대로 올라오나 확인후

# cmrunnode hostname 
으로 클러스터에 다시 조인

hostname :/] bdf
