3. 删除所有的LVM
取消挂载的分区
[root@linux tmp]# umount /tmp/lvm/
删除LV
[root@linux tmp]# lvremove /dev/vg1/lv1
Do you really want to remove active logical volume "lv1"? [y/n]: y
Logical volume "lv1" successfully removed
删除VG
[root@linux tmp]# vgremove vg1
Volume group "vg1" successfully removed
删除PV
[root@linux tmp]# pvremove /dev/hda5 /dev/hda7
Labels on physical volume "/dev/hda5" successfully wiped
Labels on physical volume "/dev/hda7" successfully wiped
删除物理分区的方法是使用“fdisk”命令
[root@linux tmp]# fdisk /dev/hda

实验总结：
LVM的建立和删除，增加容量和容量减小是一个互逆的过程。
