这种情况下配置有些注意事项。 否则会在执行root.sh命令的时候，报错：

[root@rac1 init.d]# /u01/app/oracle/product/crs/root.sh

WARNING: directory '/u01/app/oracle/product' is not owned by root

WARNING: directory '/u01/app/oracle' is not owned by root

WARNING: directory '/u01/app' is not owned by root

PROT-1: Failed to initialize ocrconfig

Failed to upgrade Oracle Cluster Registry configuration

一般出现这个问题的原因有几种：

（1） Bug

       这种情况参考：

       Executing root.sh errors with "Failed To Upgrade Oracle Cluster Registry Configuration" [ID 466673.1]

（2） raw 设备的权限问题

crwxrwxr-x 1 oracle oinstall 162, 4 Aug 22 11:19 raw4
crwxrwxr-x 1 oracle oinstall 162, 3 Aug 22 11:19 raw3
crw-r----- 1 root   oinstall 162, 1 Aug 22 14:53 raw1
crw-r--r-- 1 oracle oinstall 162, 2 Aug 22 14:55 raw2

权限要设置成如下：

chown root.oinstall /dev/raw/raw[1-2]
chown oracle.oinstall /dev/raw/raw[3-5]


chmod 775 /dev/raw/raw[1-2] 
chmod 775 /dev/raw/raw[3-5]

可以在udev的规则里设置， 也可以把权限添加到/etc/rc.d/rc.local  中。

（3） raw 设备读写问题


本次遇到的问题主要是因为bug引起（p4679769）
下载该patch后，将文件覆盖crs/bin目录下的clsfmt.bin文件
清空ocr、voting disk的raw，再次运行./root.sh后恢复正常
