Oracle RAC 添加和删除Voting Disks

link

添加删除voting Disk示例：

环境：

• [oracle@node2 ~]$ uname -a  
• Linux node2 2.6.18-164.el5 #1 SMP Tue Aug 18 15:51:54 EDT 2009 i686 i686 i386 GNU/Linux  
  

• SQL> select * from v$version;  
•   
• BANNER  
• ----------------------------------------------------------------  
• Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 - Prod  
• PL/SQL Release 10.2.0.1.0 - Production  
• CORE    10.2.0.1.0      Production  
• TNS for Linux: Version 10.2.0.1.0 - Production  
• NLSRTL Version 10.2.0.1.0 - Production  
  
  

1.查看当前的Voting Disks和关闭Oracle Clusterware

注意：添加和删除Voting Disk应先关闭所有节点Oracle  Clusterware。虽然加-force参数能在线操作，但有可能会损坏集群配置。

• [oracle@node1 ~]$ crsctl query  css votedisk  
• 0.     0    /dev/raw/raw2  
•   
• located 1 votedisk(s).
  

• [iyunv@node1 bin]# ./crsctl stop crs  
• Stopping resources.  
• Successfully stopped CRS resources   
• Stopping CSSD.  
• Shutting down CSS daemon.  
• Shutdown request successfully issued.  
• [iyunv@node2 bin]# ./crsctl stop crs  
• Stopping resources.  
• Successfully stopped CRS resources   
• Stopping CSSD.  
• Shutting down CSS daemon.  
• Shutdown request successfully issued.  
  

2.增加Voting Disk

• [iyunv@node1 bin]# ./crsctl add css votedisk /dev/raw/raw5 -force  
• Now formatting voting disk: /dev/raw/raw5  
• successful addition of votedisk /dev/raw/raw5.  
  

如果不加-force则会出现如下情况：

• [iyunv@node1 bin]# ./crsctl add css votedisk /dev/raw/raw6  
• Cluster is not in a ready state for online disk addition  
  

3.查看刚添加的Voting Disk

• [oracle@node1 ~]$ crsctl query  css votedisk  
• 0.     0    /dev/raw/raw2  
• 1.     0    /dev/raw/raw5  
  

可以看到raw5已添加成功。

4.删除Voting Disk（先查看和关闭Oracle clusterware，同上）

• [iyunv@node1 bin]# ./crsctl delete css votedisk /dev/raw/raw5 -force  
• successful deletion of votedisk /dev/raw/raw5.  
  

如果不加-force则会出现如下情况：

• [iyunv@node1 bin]# ./crsctl delete css votedisk /dev/raw/raw5  
• Cluster is not in a ready state for online disk removal  
  

5.查看是否已删除

• [iyunv@node1 bin]# ./crsctl query  css votedisk  
• 0.     0    /dev/raw/raw2  
•   
• located 1 votedisk(s).  
  

只剩下raw2说明已删除
