Solaris 10 磁盘镜像--做完了，如何验证磁盘镜像是正确的

wanfei163 发表于 2015-07-29 09:06

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 c1t0d0s7c1t1d0s7

   metainit -f d10 1 1 c1t0d0s0

   metainitd20 1 1 c1t1d0s0

   metainitd0 -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

   metainitd21 1 1 c1t1d0s1

   metainitd1 -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

c1t1d0 Yes id1,ssd@n2000000c50f0b4d9
c1t0d0 Yes id1,ssd@n2000000c50f0cafb

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

这状态明显不对 c1t1d0盘有问题吧 iostat -En 看看harderror数量

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？

东方蜘蛛 发表于 2015-07-29 13:03

metareplace -e d0 c1t1d0s0
metareplace -e d1 c1t1d0s1

wanfei163 发表于 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？

wanfei163 发表于 2015-07-29 13:21

好像都不行
