Mount disk volume (Centos) on linux debian

วิธีทำ
1. เปิด Terminal ใช้คำสั่ง vgdisplay ตรวจสอบ Disk volume

termcb:~ # vgdisplay
--- Volume group ---
VG Name VolGroup00
System ID
Format lvm2
Metadata Areas 1
Metadata Sequence No 3
VG Access read/write
VG Status resizable
MAX LV 0
Cur LV 2
Open LV 0
Max PV 0
Cur PV 1
Act PV 1
VG Size 27.84 GB
PE Size 32.00 MB
Total PE 891
Alloc PE / Size 890 / 27.81 GB
Free PE / Size 1 / 32.00 MB
VG UUID ryYRi4-mXOd-XFaW-4xnR-h1cl-hphh-5QQnlM

2. ใช้คำสั่ง lvscan เช็คสถานะ Hard disk

termcb:~ # lvscan
inactive '/dev/VolGroup00/LogVol00' [26.06 GB] inherit
inactive '/dev/VolGroup00/LogVol01' [1.75 GB] inherit

3. ใช้คำสั่ง ก่อน Mount disk

modprobe dm-mod
vgchange -ay

4. ใช้คำสั่งในข้อ 2. เช็คสถาน Hard disk อีกครั้ง จะพบว่า Disk Active

termcb:~ # lvscan
ACTIVE '/dev/VolGroup00/LogVol00' [26.06 GB] inherit
ACTIVE '/dev/VolGroup00/LogVol01' [1.75 GB] inherit

5. Mount hard disk เพื่อใช้งาน


mount /dev/VolGroup00/LogVol00 /mount/point
