新安装了Oracle 11g rac之后，不知道是什么原因导致第二个节点上的crsd无法启动？其错误消息是CRS-4535: Cannot communicate with Cluster Ready Services。其具体的错误信息还需要查看crsd.log日志才知道。
1、环境
[root@linux2 ~]# cat /etc/issue
Enterprise Linux Enterprise Linux Server release 5.5 (Carthage)
Kernel \r on an \m
[root@linux2 bin]# ./crsctl query crs activeversion
Oracle Clusterware active version on the cluster is [11.2.0.1.0]
#注意下文中描述中使用了grid与root用户操作不同的对象。
2、错误症状
[root@linux2 bin]# ./crsctl check crs
CRS-4638: Oracle High Availability Services is online
CRS-4535: Cannot communicate with Cluster Ready Services #CRS-4535
CRS-4529: Cluster Synchronization Services is online
CRS-4533: Event Manager is online

#从上面的分析可知，应该是ASM实例没有启动的原因导致了crsd进程无法启动
