How to recover from root.sh on 11.2 Grid Infrastructure Failed
从10g的clusterware到11g Release2的Grid Infrastructure，Oracle往RAC这个框架里塞进了太多东西。虽然照着Step by Step Installation指南步步为营地去安装11.2.0.1的GI，但在实际执行root.sh脚本的时候，不免又要出现这样那样的错误。例如下面的一例：
[root@rh3 grid]# ./root.sh
Running Oracle 11g root.sh script...
The following environment variables are set as:
ORACLE_OWNER= maclean
ORACLE_HOME= /u01/app/11.2.0/grid

ADVM/ACFS is not supported on oraclelinux-release-5-5.0.2 一个节点上的root.sh脚本运行居然提示说ADVM/ACFS不支持OEL 5.5，但实际上Redhat 5或者OEL 5是目前仅有的少数支持ACFS的平台(The ACFS install would be on a supported Linux release - either Oracle Enterprise Linux 5 or Red Hat 5)。 检索Metalink发现这是一个Linux平台上的 Bug 9474252: 'ACFSLOAD START' RETURNS "ADVM/ACFS IS NOT SUPPORTED ON DHL-RELEASE-..."。 因为以上Not Supported错误信息在另外一个节点(也是Enterprise Linux Enterprise Linux Server release 5.5 (Carthage)) 运行root.sh脚本时并未出现，那么一般只要找出2个节点间的差异就可能解决问题了:
未出错节点上release相关rpm包的情况 [maclean@rh6 tmp]$ cat /etc/issue Enterprise Linux Enterprise Linux Server release 5.5 (Carthage) Kernel \r on an \m [maclean@rh6 tmp]$ rpm -qa|grep release enterprise-release-notes-5Server-17 enterprise-release-5-0.0.22 出错节点上release相关rpm包的情况 [root@rh3 tmp]# rpm -qa | grep release oraclelinux-release-5-5.0.2 enterprise-release-5-0.0.22 enterprise-release-notes-5Server-17以上可以看到相比起没有出错的节点，出错节点上多安装了一个名为oraclelinux-release-5-5.0.2的rpm包，我们尝试来卸载该rpm是否能解决问题，补充实际上该问题也可以通过修改/tmp/.linux_release文件的内容为enterprise-release-5-0.0.17来解决，而无需如我们这里做的卸载名为oraclelinux-release-5*的rpm软件包：
[root@rh3 install]# rpm -e oraclelinux-release-5-5.0.2
[root@rh3 grid]# ./root.sh

'UpdateNodeList' was successful. 以上虽然绕过了"ADVM/ACFS is not supported"的问题，但又出现了"FATAL: Module oracleoks/oracleadvm/oracleacfs not found"，Linux下ACFS/ADVM相关加载Module无法找到的问题，查了下metalink发现这是GI 11.2.0.2中2个被确认的 bug 10252497或 bug 10266447，而实际我所安装的是11.2.0.1版本的GI........ 好了，所幸我目前的环境是使用NFS的存储，所以如ADVM/ACFS这些存储选项的问题可以忽略不计，准备在11.2.0.2上再测试下。 不得不说11.2.0.1版本GI的安装存在太多的问题，以至于Oracle Support不得不撰写了不少相关故障诊断的文档，例如: <Troubleshooting 11.2 Grid Infastructure Installation Root.sh Issues [ID 1053970.1]>, <How to Proceed from Failed 11gR2 Grid Infrastructure (CRS) Installation [ID 942166.1]>。目前为止还没体验过11.2.0.2的GI，希望它不像上一个版本那么糟糕！
