cp /etc/inittab.orig /etc/inittab rm -rf /var/tmp/.oracle rm -rf /tmp/.oracle

(由于执行rootdelete.sh时删除了上面的一些目录或文件，故仅需补充删除存在的即可)

6，使用dd清除vote disk和ocr，需要修改成相应的文件 dd if=/dev/zero of=/dev/raw/raw1 bs=8192 count=12800 dd if=/dev/zero of=/dev/raw/raw2 bs=8192 count=12800

GDGZ-DCS-SV02C-RAC01:/opt # dd if=/dev/zero of=/dev/raw/raw2 bs=8192 count=128000 dd: writing `/dev/raw/raw2': No space left on device 123500+0 records in 123499+0 records out

（从第4步结果提示来看，应该ocr已经清除了，可以尝试只清除VOTEDISK,可惜我先执行了dd清除命令）

二，重建OCR（这里我独创性的使用图形工具runInstaller，模仿新建的方法来重建OCR） 1，由于首次安装CRS时需要新的空的/opt/oracle /opt/oracrs目录，所以先在各个节点执行如下命令： cd /opt

mv oracle oracle_old mv oracrsoracrs_old

mkdir oracle mkdiroracrs

mkdir /opt/oracle/oraInventory

chownoracle:dba /opt/oracle/oraInventory chmod 755 /opt/oracle/oraInventory chown -R oracle:dba /opt/oracle chmod -R 770 /opt/oracle chown -R oracle:dba /opt/oracrs chmod -R 770 /opt/oracrs

2,xmanager登陆RAC1节点使用图形工具安装CRS（这里可以参考RAC安装过程的CRS安装部分）

oracle用户执行/opt/orabak/clusterware/runInstaller

需要注意的是，这里的CRS安装配置需要和第一次安装配置保持完全一致！！！

安装最后需要根据图形界面提示在各个RAC节点执行root.sh

GDGZ-DCS-SV01C-RAC01:/opt/oracle # /opt/oracrs/root.sh Checking to see if Oracle CRS stack is already configured /etc/oracle does not exist. Creating it now.

点击OK后检查有一个失败，根据提示：/opt/oracrs/cfgtoollogs下有出错命令日志 /opt/oracrs/bin/cluvfy stage -post crsinst -n

这是root信任关系导致，可以不理！！！
