本文档提供了一步一步的指导，教你如何为OpenSolaris系统创建一个可启动的ZFS根目录镜像。教程首先要求在磁盘A上安装OpenSolaris，然后格式化磁盘B，并通过特定命令将磁盘B附加到ZFS根池中。接下来，将GRUB引导加载程序安装到磁盘B，并进行故障切换测试，以确保系统能够在磁盘A发生故障时从磁盘B启动。

This is a simple Tutorial how you can create a bootable ZFS Root Mirror with Opensolaris. I had some help from both Opensolaris-Forums (com/org) and this Blog from Malachi.

And here we go with the Tutorial:

Making a bootable ZFS Root Mirror

1. Install Opensolaris to Disk A ( c3d0s0).

2. Format Disk B ( c3d1s0) properly:
host:# format
(choose fdisk)
(create 100% Standard Solaris Partition over the full Disk)

3. Overwrite the Diskformat properly:
host:# prtvtoc /dev/rdsk/c3d0s2 | fmthard -s - /dev/rdsk/c3d1s2
(NOTE: s2! on BOTH Disks)

4. Attach Disk B to the ZFS Root Pool:
host:# zpool attach -f rpool c3d0s0 c3d1s0

5. Install the GRUB-Stuff to Disk B:
host:# installgrub -m /boot/grub/stage1 /boot/grub/stage2 /dev/rdsk/c3d1s0

6. Test the worst Case: Disk A fails, you can still boot into Disk B
- Remove Disk A
- Replace it with an emtpy Disk C
- Start the System: Choose to boot from Disk B in the Bios
- Repeat Steps 2. till 5. for Disk C (swap c3d0s0 and c3d1s0)
- Start the System like before (from Disk C)
