solaris 10镜像同步维护

1. 查看镜像发现有镜像块需要被维护

   root@WEBServer # metastat
   d20: Mirror
   Submirror 0: d21
     State: Okay    
   Submirror 1: d22
     State: Needs maintenance 
   Resync in progress: 0 % done
   Pass: 1
   Read option: roundrobin (default)
   Write option: parallel (default)
   Size: 277764096 blocks

2. 对需要维护的镜像做重新同步操作

   #metareplace -e d20 c0t0d0s0 

   查看mirror状态,看到同步过程Resyncing。

   root@WEBServer # metastat
   d20: Mirror
   Submirror 0: d21
     State: Resyncing    
   Submirror 1: d22
     State: Needs maintenance 
   Resync in progress: 0 % done
   Pass: 1
   Read option: roundrobin (default)
   Write option: parallel (default)
   Size: 277764096 blocks
   d21: Submirror of d20
   State: Resyncing    
   Size: 277764096 blocks
   Stripe 0:
       Device              Start Block  Dbase State        Hot Spare
       c0t0d0s0                   0     No    Resyncing   
   d22: Submirror of d20
   State: Needs maintenance 
   Size: 277764096 blocks
   Stripe 0:
       Device              Start Block  Dbase State        Hot Spare
       c0t1d0s0                   0     No    Last Erred  

3. 等d21完成后，再同步d22。时间很长，每步要等4-5小时。

   #metareplace -e d20 c0t1d0s0  

4. 最后执行metastat查看状态正常

   root@WEBServer # metastat
   d20: Mirror
   Submirror 0: d21
     State: Okay         
   Submirror 1: d22
     State: Okay         
   Pass: 1
   Read option: roundrobin (default)
   Write option: parallel (default)
   Size: 277764096 blocks
   d21: Submirror of d20
   State: Okay         
   Size: 277764096 blocks
   Stripe 0:
       Device              Start Block  Dbase State        Hot Spare
       c0t0d0s0                   0     No    Okay
