ADVMACFSis not supported on oraclelinux-release-5-8.0.2
错误信息：
ACFS-9459: ADVMACFS is not supported onoraclelinux-release-5-8.0.2
错误介绍：
在Oracle11gR2 Grid安装的过程中，在第二个节点执行root.sh脚本的时候报次错误，从错误现象来看，是由于ADVMACFS不支持oraclelinux5.8.0.2这个版本。导致撂出这个错误。
错误分析：
那么既然是不支持oraclelinux-release-5.8.0.2这个版本，是不是有什么办法解决，ADVMACFS到底是个什么东西；ADVMACFS是不是必须要装的呢，需要打什么补丁来进行安装，或者更换操作系统来完成这次Grid的部署。
从这几个问题中，我们开始引入下文：
1、 什么是ACFS：
我们引入官方的如下这段话：
Oracle ASM Cluster File System (ACFS)
A general-purpose POSIX, X/OPEN and Windows compliantfile system designed for single node and cluster configurations. ACFS ismanaged using native operating system commands, ASM asmcmd and the OracleEnterprise Manager. ACFS supports advanced data services such as point-in-timecopy snapshots, file system replication and tagging as well as file systemsecurity and encryption.
ACFS是一通用的POSIX,X/ OPEN和Windows兼容的文件系统设计为单节点和集群配置。ACFS管理使用本机操作系统命令,ASMasmcmd和Oracle企业管理器。ACFS支持高级数据服务,如：时间点复制快照文件系统复制和标签以及文件系统安全性和加密。
我们简单点讲，就是Oracle11gR2以ASM技术为基础新的推出来的自动存储集群文件系统，我们可以通过ACFS对磁盘进行空间进行有效的管理，卷组的动态调整，磁盘限额等工作。
详细参考Oracle 11g New Features
http://docs.oracle.com/cd/E11857_01/em.111/e11982/whats_new.htm
2、 ACFS既然有这么强大的功能，那是不是必须要进行安装的呢。
这个并不是必须要装的，如果安装了将会更方便的进行Oracle所用磁盘的管理。
3、 既然爆出不支持oraclelinux5.8.0.2，到底支持哪些版本，有没有什么办法可以解决：

Note 5:ACFS/ADVM 11.2.0.3 are not supported/certified yet on "2.6.32-200"kernels (e.g. below):
[root@dbaasm]# ./acfsdriverstate -orahome $GRID_HOME supported
ACFS-9459: ADVM/ACFS is not supported on this OS version:'2.6.32-200.19.1.el5uek'
Support for "2.6.32-200" kernels will start in the firstGI PSU 11.2.0.3.1 (11.2.0.3 GIPSU #1), (RFI Bug:13241736 & Bug:12825835).
总结：
我们从上图可以看书，必须将数据库升级到11.2.0.3的版本，才能支持OL5/RHEL5 Update 3 and later (2.6.18 basedkernels)
