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.
同样地，我们仍需要检查引导列表并为现在这个非镜像的卷组重新创建引导映像。
Again, we also need to check the boot list and recreate the boot image for this now non-mirrored volume group.
可以重新分配和镜像逻辑卷。
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).
在有数据保护(镜像或aid - Z)的卷中，可自动读取或重新生成备用数据。
In a volume that has data protection (mirroring or RAID-Z), the alternate data can be read or regenerated automatically.
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.
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.
如何镜像逻辑卷？
然后我们镜像此卷组和这个新的hdisk。
如果适用的话，用mirrorios为根卷组建立镜像。
Mirror the root volume group with the mirrorios command, if applicable.
首先，我们强制创建第一个镜像的卷(请参见清单2)，我将其称为d1。
First, let's force the creation of the first mirrored volume (see Listing 2), which I've referred to as d1.
在使用内部硬驱时，第一步均要为每个卷组配置至少两个磁盘，并使用mirrorvg命令镜像这些硬盘驱动器。
When using internal hard drives, the first step should always be to have at least two disks per volume group and to mirror the hard drives with the mirrorvg command.
lvconvert：在线性卷和镜像或快照之间进行转换。
Lvconvert converts between a linear volume and a mirror or snapshot and vice versa.
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.
我们将卷组从DS8300磁盘（hdisk2）镜像到新的NetApp 磁盘（hdisk12）。
We mirror the volume group from the DS8300 disk (hdisk2) to the new NetApp disk (hdisk12).
因为已经开启了镜像写一致性检查(MWC)，所以如果卷位于边缘，那么应该能够更好地为其提供服务。
Because Mirror Write Consistency (MWC) is on, the volume would have been better served if it were placed on the edge.
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).
分割镜像(split mirror)是具有同一性、独立性、瞬时性的磁盘卷拷贝，分割镜像可以被附加在其他系统上。
A split mirror is an identical, independent, and instantaneous copy of a disk volume that can be attached to a different system.
作为一种预先的防范措施，我们验证了rootvg现已被镜像、在引导列表中包含了新磁盘并为所镜像的卷组创建了新的引导映像。
As a pre-cautionary measure, we verify that rootvg is now mirrored, include the new disk in the boot list and create a new boot image for the mirrored volume group.
为现存的卷添加镜像，会因在不同磁盘上维持卷数据的多份副本而造成数据重复。
Adding a mirror to an existing volume provides data redundancy by maintaining multiple copies of a volume's data on different disks.
为现存的卷添加镜像，会因维持卷数据的多份副本而造成数据重复。
Adding a mirror to an existing volume provides data redundancy by maintaining multiple copies of a volume's data.
