删除操作不再演示
看来在线添加votedisk是可以成功的，在10g下需要使用 -force选项，但是网上有资料表示：在添加或者删除votedisk时，最好停掉所有应用。
如何重新创建ocr和votedisk（在ocr和votedisk损坏，并且没有备份时，这是非常有用的）？
首先，在所有的节点停止cluster
[root@node1 ~]# ocrcheck
Status of Oracle Cluster Registry is as follows :
Version : 2
Total space (kbytes) : 1125736
Used space (kbytes) : 3852
Available space (kbytes) : 1121884
ID : 849560479
Device/File Name : /dev/raw/raw1
Device/File integrity check succeeded
Device/File not configured
Cluster registry integrity check succeeded
[root@node1 ~]# crsctl query css votedisk
0. 0 /dev/raw/raw2
1. 0 /dev/raw/raw4
located 2 votedisk(s).
[root@node1 ~]# crsctl check crs
Failure 1 contacting CSS daemon
Cannot communicate with CRS
Cannot communicate with EVM
[root@node1 ~]# ssh node2 /u01/app/crs_home/bin/crsctl check crs
Failure 1 contacting CSS daemon
Cannot communicate with CRS
Cannot communicate with EVM
在每个节点执行rootdelete.sh脚本
[root@node1 ~]# cd $CRS_HOME/install
[root@node1 install]# ./rootdelete.sh
Shutting down Oracle Cluster Ready Services (CRS):

Cleaning up Network socket directories

在任意节点上，执行rootdeinstall.sh脚本（只需在一个节点上运行即可）
[root@node1 install]# ./rootdeinstall.sh

在所有节点上执行root.sh脚本?
[root@node1 crs_home]# pwd
/u01/app/crs_home
[root@node1 crs_home]# ./root.sh
