rac安装clusterware遇到：Failed to upgrade Oracle Cluster Registry configuration

在RAC安装中，有一步是要安装clusterware。当clusterware快要安装完的时候，会需要我们执行两个脚本，

关于rac安装执行脚本的含义，参考：http://blog.csdn.net/cymm_liu/article/details/11468657

当执行第二个脚本root.sh的时候报了如下错误：Failed to upgrade Oracle Cluster Registry configuration

关于这个错误，很简单的理解，就是OCR磁盘不能配置，具体什么原因造成的呢？参考这篇文章：

好了看完了这篇文章，基本心理有底了，该如何解决了：

1、首先我测试了是不是bug引起的：

[root@rac2 bin]# ./clsfmt.bin ocr /dev/raw/raw1
clsfmt: Failure trying to resize OCR file from 205599744 bytes to 205602816 bytes
clsfmt: successfully initialized file /dev/raw/raw1

结果是，我的机器不存在这个bug。。

2、继续检查权限问题：

[root@rac2 bin]# ls -rlt /dev/raw
total 0
crw-rw---- 1 oracle oinstall 162, 7 Sep  8 19:07 raw7
crw-r--r-- 1 oracle oinstall 162, 3 Sep  8 19:07 raw3
crw-rw---- 1 oracle oinstall 162, 4 Sep  8 19:07 raw4
crw-r--r-- 1 oracle oinstall 162, 5 Sep  8 19:07 raw5
crw-r--r-- 1 oracle oinstall 162, 6 Sep  8 19:07 raw6
crw-r----- 1 root   oinstall 162, 2 Sep  8 20:54 raw2
crw-r----- 1 root   oinstall 162, 1 Sep  9 10:13 raw1

从输出结果看，也是没有问题的。

3、上面都没有问题，决定看看日志是怎么回事，因为之前我不知道有日志可以查，如果知道。第一步就应该去看日志：

[root@rac2 client]# pwd
/u01/app/oracle/product/10.2.0/crs/log/rac2/client

[root@rac2 client]# more ocrconfig_20694.log

通过查看日志，发现好像是因为我之前执行过root.sh，但是出现了错误，所以不能再执行了。。所以，我觉得清空一下裸设备：

检查裸设备I/O是否正常：

[root@rac1 rc.d]# hdparm -t /dev/raw/raw[1-5]

/dev/raw/raw1:
 Timing buffered disk reads:  196 MB in  0.60 seconds = 327.12 MB/sec

/dev/raw/raw2:
 Timing buffered disk reads:  196 MB in  0.14 seconds = 1446.42 MB/sec

/dev/raw/raw3:
 Timing buffered disk reads:  196 MB in  0.14 seconds = 1424.63 MB/sec

/dev/raw/raw4:
 Timing buffered disk reads:  read(2097152) returned 1024 bytes    ————这个是扩展分区，没有I/O，正常

/dev/raw/raw5:
 Timing buffered disk reads:  196 MB in  0.18 seconds = 1065.75 MB/sec
[root@rac1 rc.d]# 

把orc对应的裸设备清空下：

[root@rac1 client]# dd if=/dev/zero of=/dev/raw/raw1
dd: writing to `/dev/raw/raw1': No space left on device
401563+0 records in
401562+0 records out
205599744 bytes (206 MB) copied, 26.8478 seconds, 7.7 MB/s
[root@rac1 client]# dd if=/dev/zero of=/dev/raw/raw2
dd: writing to `/dev/raw/raw2': No space left on device
401626+0 records in
401625+0 records out
205632000 bytes (206 MB) copied, 27.7136 seconds, 7.4 MB/s

4、再次执行root.sh脚本，出现新的错误：

[root@rac1 crs]# ./root.sh 
WARNING: directory '/u01/app/oracle/product/10.2.0' is not owned by root
WARNING: directory '/u01/app/oracle/product' is not owned by root

Failure initializing entries in /etc/oracle/scls_scr/rac1.
[root@rac1 crs]# ls

从这个错误看，是系统少了libstdc++.so.5这个库文件。这样的话，我从网上找对应的库文件，放到/usr/lib目录下，就能解决这个问题。

在下面包里有 libstdc++.so.5然后复制到/usr/lib里

5、再次清空ocr磁盘，执行root.sh：

[root@rac1 crs]# ./root.sh
WARNING: directory '/u01/app/oracle/product/10.2.0' is not owned by root
WARNING: directory '/u01/app/oracle/product' is not owned by root

到此，rac1上执行root.sh脚本成功》。
