Oracle RAC 添加和删除Voting Disks

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：

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。

[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.

如果不加-force则会出现如下情况：

[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.

如果不加-force则会出现如下情况：

[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).
