标题: Solaris 10 磁盘镜像--做完了，如何验证磁盘镜像是正确的
1）环境：

   V480R 2个72G硬盘

   分区： / -->  c1t0d0s0(剩下的硬盘空间) ; swap  -->  c1t0d0s1  (8G) ；  c1t0d0s7（50M）

2）方法：

   网上查的，主要步骤如下：

   prtvtoc /dev/rdsk/c1t0d0s2  |  fmthard -s - /dev/rdsk/c1t1d0s2

   metadb -a -f -c 3 c1t0d0s7  c1t1d0s7

   metainit -f d10 1 1 c1t0d0s0

   metainit  d20 1 1 c1t1d0s0

   metainit  d0 -m d10

   cp /etc/vfstab /etc/vfstab.bak

   metaroot d0

   lockfs -fa

   reboot

   下面做swap的镜像

   metainit -f d11 1 1 c1t0d0s1

   metainit  d21 1 1 c1t1d0s1

   metainit  d1 -m d11

   下面做子镜像

   metattach d0 d20

   metattach d1 d21

   metastat |  grep % /* 这时我可以看到同步，从1%---到9%，但结束收的状态不是ok状态；

   修改vfstab表，用init 6 重启系统

3）当前状态
bash-3.00# more /etc/vfstab
#device       device       mount          FS    fsck mount mount
#to mount    to fsck       point          type pass at boot options

4）我用metasync 命令重新同步，可以看到%比从1到99%，也重启了，但状态还是如下。

d20: Submirror of d0
State: Needs maintenance

请问各位大侠，这个对吗？如果不对，我看如何做，请告诉我具体命令，谢谢。初次安装，请指教

看磁盘，没有报错。我可以按照更换硬盘的方式，重新镜像一下吗？能告诉一个meta replace 更换命令的正确步骤吗？

作者: 东方蜘蛛 时间: 2015-07-29 13:03
metareplace -e d0 c1t1d0s0
metareplace -e d1 c1t1d0s1

作者: wanfei163 时间: 2015-07-29 13:19
只要重新输入这个命令就可以了，需要插拔硬盘吗？

10几分钟能同步完？

作者: wanfei163 时间: 2015-07-29 16:54
就一个solaris 10 end system 安装。其他软件都没有。

重新再安装一次？  ？

solaris10的软镜像同步没这么快吧；我记得我做完后修改了/etc/system参数同步都至少要两个钟头呢，而且是新装系统，没有任何应用来着！

非常谢谢了。后来连续更换了2个硬盘，镜像好了。但我是重新安装了。

非常感谢，更换2个备用的硬盘，重新安装后，镜像都做好了。
