Oracle RAC 备份和恢复Voting Disks 参考：http://blog.csdn.net/laoshangxyc/article/details/8670425
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).
- [root@node1 bin]# ./crsctl stop crs
- Stopping resources.
- Successfully stopped CRS resources
- Stopping CSSD.
- Shutting down CSS daemon.
- Shutdown request successfully issued.
- [root@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
- [root@node1 bin]# ./crsctl add css votedisk /dev/raw/raw5 -force
- Now formatting voting disk: /dev/raw/raw5
- successful addition of votedisk /dev/raw/raw5.
- [root@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）
- [root@node1 bin]# ./crsctl delete css votedisk /dev/raw/raw5 -force
- successful deletion of votedisk /dev/raw/raw5.
- [root@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
- [root@node1 bin]# ./crsctl query css votedisk
- 0. 0 /dev/raw/raw2
- located 1 votedisk(s).
只剩下raw2说明已删除
