逻辑卷快照和虚拟化：

[root@station157 ~]# lvcreate -s -L 200M /dev/rhel/winserver
Logical volume "lvol0" created.

复制代码

当使用这个快照，超过200M的变化量时，块照会被自动回收（摧毁）。

Aug 20 20:39:25 station157 kernel: device-mapper: snapshots: Invalidating snapshot: Unable to allocate exception.
Aug 20 20:39:25 station157 lvm[26597]: WARNING: Snapshot rhel-lvol0 changed state to: Invalid and should be removed.
Aug 20 20:39:25 station157 dmeventd[26597]: No longer monitoring snapshot rhel-lvol0.
