CRS-4639: Could not contact Oracle High Availability Services
CRS-4639: Could not contact Oracle High Availability Services
原因，crs没有启动
方法1、oracle中的bug，
启动之前需要执行
/bin/dd if=/var/tmp/.oracle/npohasd of=/dev/null bs=1024 count=1 （如果想让重启能够执行，需要加入rc.local中，两个节点）
然后再执行
[root@rac2 bin]# ./crsctl start crs
方法1如果不行可以尝试方法2
[root@rac2 install]# /u01/app/11.2.0/grid/crs/install/roothas.pl -deconfig -force -verbose
然后重新配置
[root@rac2 grid]# ./root.sh
Running Oracle 11g root.sh script...
The following environment variables are set as:
ORACLE_OWNER= oracle
ORACLE_HOME= /u01/app/11.2.0/grid
...
即可
如果是centos6以上还需要运行
[root@rac2 ~]# /bin/dd if=/var/tmp/.oracle/npohasd of=/dev/null bs=1024 count=1
检查
[root@rac2 bin]# ./crsctl check crs
CRS-4638: Oracle High Availability Services is online
CRS-4537: Cluster Ready Services is online
CRS-4529: Cluster Synchronization Services is online
CRS-4533: Event Manager is online
另外，注意的是，如果还是在重启服务器之后不能启动crs，则需要在启动crs之前执行命令（两个节点）
/bin/dd if=/var/tmp/.oracle/npohasd of=/dev/null bs=1024 count=1
追根就是oracle的一个bug
[root@rac2 bin]# ./crsctl check crs
CRS-4638: Oracle High Availability Services is online
CRS-4535: Cannot communicate with Cluster Ready Services
CRS-4530: Communications failure contacting Cluster Synchronization Services daemon
CRS-4534: Cannot communicate with Event Manager
这个问题有几个原因
1、使用./crsctl start crs 之后立即执行了check，需要等待
2、需要查看节点连通状态，公有网络私有等，还有就是disk的属性
[root@rac2 disks]# ll
