oracle10g rac中的节点上crs无法启动。。。求高手指定迷津。。

蓦然princes

环境说明： oracle10gr2  linux5.3

今天rac中的节点1突然没法用了，检查后发现是crs服务没有启动。。经过一晚上的排错，还是没能解决。。求高手帮忙看看，到底哪里出了问题。

错误：
[root@rac1 bin]# ./crsctl check crs
Failure 1 contacting CSS daemon
Cannot communicate with CRS
Cannot communicate with EVM

下面是我的排错过程和相关日志。。
首先我查看了ClusterWare日志：
#more alertrac1.log

在查看

小弟我也看不太懂到底问题出在了那， 但是感觉好像是OCR设备在写的时候发生了错误。于是我查看了rac1的ocr文件

[oracle@rac1 oracle]$ more ocr.loc
ocrconfig_loc=/u01/oracle/OraCrs10g_home/cdata/localhost/local.ocr
local_only=TRUE
发现这个文件是错的，于是我该过来，和rac2上改成一样的。rac2是正常的。

[root@rac1 rac1]# more /etc/oracle/ocr.loc
ocrconfig_loc=/dev/raw/raw1
local_only=FALSE

重新启动rac1机器，还是没法启动crs。。。求高手指点小弟一下，到底哪里出了问题。。。感激不尽。。。

补充一下， 我使用iscsi服务作为共享存储的。。。。

由于是oracle10gr2的版本，所以，有两个裸设备raw1和raw2，期中raw1作为OCR， raw2作为votedisk。下面是具体信息

rac2（ok）  rac1（不能启动crs）

rac2和rac1的裸设备情况：
