RedHat 4 RAC 安装crs的一个小问题

RedHat 4 RAC 安装crs的一个小问题（裸设备-ocfs 同）

故障描述如下，出现在第一次安装crs失败，再次安装时，失败后做了如下处理：

rm -f /etc/init.d/init.cssd

rm -f /etc/init.d/init.crs

rm -f /etc/init.d/init.crsd

rm -f /etc/init.d/init.evmd

find /etc -name '*init.crs*' -exec rm {} ;

rm -f /etc/inittab.crs

/etc/inittab 去除文件末尾crs部分

重启

rm -rf /u01/app/oracle/oraInventory -

rm -rf oracle 目录 或者./runInstaller 删除安装组件

rm -rf /etc/oracle/

rm -rf /etc/ora*

rm -rf <CRS安装目录>

rm -rf /tmp/*

rm -rf /var/tmp/*

还有/etc/inittab中对应的条目去处，在最后边，

rm -rf /etc/oracle

完

再次安装时执行到root.sh

后报错，

[root@Red2 ~]# /opt/ora10g/oraInventory/orainstRoot.sh

Changing permissions of /opt/ora10g/oraInventory to 770.

Changing groupname of /opt/ora10g/oraInventory to oinstall.

解决方法1：ocfs

dd if=/dev/zero of=/dev/voting（设备名称） bs=8192 count=2560

dd if=/dev/zero of=/dev/ocr（设备名称）bs=8192 count=12800

解决方法2：裸设备

dd if=/dev/zero of=/dev/sdb1 bs=8192 count=2000

dd if=/dev/zero of=/dev/sdc1 bs=8192 count=2000

原理相同，注意在第一个节点上报错后，就不要在第二个节点上也执行root.sh 了，马上执行上述步骤修复，因为crs是很麻烦的，如果两个节点都执行晚了，再修复恐要重新安装crs了，那可是麻烦的很了，不果我没试过，有兴趣可以一试，呵呵。

-----另一个问题，比较小，细心点就不会犯了，呵！

。。。。后边略，可见是ip问题

查host 结果red2的少了 127.0.0.1 倒！
