在Linux AS 5.4上安装Oracle RAC 10.2.0.1，使用多路径软件映射出来的虚拟磁盘分区保存OCR和VOTE DISK信息。执行root.sh时报错"Failed to upgrade Oracle Cluster Registry configuration"。

报错具体信息如下：

[root@rac11 ~]# /u01/app/oracle/product/10.2.0/crshome_1/root.sh
WARNING: directory '/u01/app/oracle/product/10.2.0' is not owned by root

分析ocrconfig.log日志，，错误信息如下：

使用dd清理raw1,raw2裸设备

dd if=/dev/zero of=/dev/raw/raw1 bs=8192K count=10

dd if=/dev/zero of=/dev/raw/raw2 bs=8192K count=10

清理结果正常，不是磁盘不能读或者保存有旧的配置信息。

于是查找oracle官网，说这是一个bug.

在RedHat 5.4 RAC multipath 配置raw，运行root.sh 时报错Failed to upgrade Oracle Cluster Registry configuration 。

使用clsfmt.bin检查一下。

[root@rac11 ~]# /u01/app/oracle/product/10.2.0/crshome_1/bin/clsfmt.bin ocr /dev/raw/raw1
clsfmt: Received unexpected error 4 from skgfifi
skgfifi: Additional information: -2

oracle 发布的补丁包p4679769_10201_Linux-x86-.zip。补丁包中的clsfmt.bin文件替换到系统bin目录的同名称文件即可。
