查看當前磁盤分區情況
fdisk -l

磁盤分區
fdisk /dev/sdb

創建PV
pvcreate /dev/sdb1
pvcreate /dev/sdb2

確認PV
pvdisplay
pvdisplay /dev/sdb1
pvdisplay /dev/sdb2

創建VG
vgcreate myVG /dev/sdb1 /dev/sdb2
or
vgcreate myVG /dev/sdb1; vgextend myVG /dev/sdb2

確認VG
vgdisplay

創建LV
lvcreate -L 400 -n vol01 myVG
lvcreate -L 1000 -n vol02 myVG
# -L size, 400M, 1000M
# -n lv‘s name

確認LV
lvdisplay

創建Filesystem
mkfs.ext3 /dev/myVG/vol01
mkfs.ext3 /dev/myVG/vol02

掛載Mount Filesystem
mkdir -p /data1
mkdir -p /data2
mount /dev/myVG/vol01 /data1
mount /dev/myVG/vol02 /data2

編輯寫入/etc/fstab
# file system|mount point|type|options|dump|pass
/dev/myVG/vol01 /data1 ext3 rw,noatime 0 0
/dev/myVG/vol02 /data2 ext3 rw,noatime 0 0

擴展LV
lvextend -L +800 /dev/myVG/vol01
# -L size 800M

重置FS大小(擴張此時才實際生效)
resize2fs /dev/myVG/vol01

刪除LV
lvremove /dev/myVG/vol02
