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(kuò)展LV
lvextend -L +800 /dev/myVG/vol01
# -L size 800M
