Oracle RAC 添加和删除Voting Disks

Oracle RAC 添加和删除Voting Disks

Oracle RAC 备份和恢复Voting Disks 参考：

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.

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
