但是，服务器说无法完全解除镜像，因为其中一个逻辑卷只有一个好拷贝，它就在出故障的磁盘上。
But the server said that it could not completely break the mirror, because the only good copy of one of the logical volumes was on the dying disk.
该命令镜像给定卷组中存在的所有逻辑卷(请参见清单12)。
This command mirrors all the logical volumes that exist on a given volume group (see Listing 12).
我们使用的是RAID5，因此不会镜像逻辑卷。
We are using RAID5, so we will not mirror the logical volumes.
逻辑卷(LV)指向一组特定的PP；一个LV最多可以指向三个PP，从而支持通过逻辑分区(LP)映射进行镜像。
Logical volumes (LVs) point to a set of specific PPs; a single LV can point to up to three PPs for mirroring through the logical partitions (LPs) mapping.
最近的LVM2 开发成果为逻辑卷提供了高可用性。 逻辑卷可以有两个或更多的镜像，镜像可以放在不同的物理卷（或不同的设备）上。
Recent LVM2 developments allow a logical volume to sport high-availability features by having two or more mirrors each which can be placed under different physical volumes (or different devices).
我只是把事情略微简单化了，因为只能选择镜像根磁盘中特定的逻辑卷(如果他们选择这样做)，方法是针对每个单独的逻辑卷使用mklvcopy命令。
I'm oversimplifying things just a little, as one can choose to mirror only certain logical volumes in the root disk, if they choose to, with the mklvcopy command for each individual logical volume.
