CRS-0184:CannotcommunicatewiththeCRSdaemon.之节点脱离集群问题解决

CRS-0184: Cannot communicate with the CRS daemon.之节点脱离集群问题解决

1、系统环境：

OEL6.5企业版

Oracle11.2.0.2 RAC + ASM

2、报错信息：

$ crs_stat -t
CRS-0184: Cannot communicate with the CRS daemon.
$ crsctl check has
CRS-4639: Could not contact Oracle High Availability Services

3、报错原因查找：

在节点1节点查看IP地址，，VIP已经不存在
$ ifconfig -a
en0: flags=1e080863,480
inet 192.168.0.117 netmask 0xffffff00 broadcast 192.168.0.255
tcp_sendspace 262144 tcp_recvspace 262144 rfc1323 1
en1: flags=1e080863,480
inet 10.10.10.1 netmask 0xff000000 broadcast 10.255.255.255
tcp_sendspace 65536 tcp_recvspace 65536 rfc1323 1
在节点2上运行“crs_stat -t”发现，节点1好像已经退出集群环境
# su - grid
$ crs_stat -t

从输出中看到节点1的VIP已经飘逸到节点2，从而判断节点1已经脱离集群。
通过"ifconfig"查看节点2上的ip信息。

4、问题解决：
清理节点1的配置信息，打算重新运行root.sh
# /u01/app/11.2.0/grid/crs/install/rootcrs.pl -verbose -deconfig -force
Using configuration parameter file: /u01/app/11.2.0/grid/crs/install/crsconfig_params
