--->看到吗，INACTIVE（没激活了），我们把它激活看看
[root@desktop21 /]# lvchange -ay /dev/vol0/snapsyslv
  Can't change snapshot logical volume "snapsyslv"
--->Can't，不能激活了，快照不能用了哦，把它移除吧
[root@desktop21 /]# lvremove /dev/vol0/snapsyslv
Do you really want to remove active logical volume snapsyslv? [y/n]: y
  Logical volume "snapsyslv" successfully removed
--->ok，已经移除了，现在可以再继续创建快照了额^_^
