Oracle 11g RAC 添加节点故障之--CRS资源启动故障
系统环境:
操作系统:RedHat EL5.5
集群软件: GI 11G
数据库软件:Oracle 11.2.0.1
故障原因:
由于新节点(node3)是从原有的老节点(node2),克隆而来,在添加新节点时,忘了修改新节点的主机名,导致出现以下故障:
1、新节点CRS service启动正常
[root@node3 ~]# 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
2、listener 资源启动失败
[root@node3 ~]# crs_stat -t
Name Type Target State Host

[root@node3 ~]# crs_stat |grep lsn
NAME=ora.LISTENER.lsnr
NAME=ora.LISTENER_SCAN1.lsnr
NAME=ora.node1.LISTENER_NODE1.lsnr
NAME=ora.node2.LISTENER_NODE2.lsnr
NAME=ora.node3.LISTENER_NODE3.lsnr
NAME=ora.node3.LISTENER_NODE3.lsnr 服务启动失败
3、listener 资源故障解决方法:
手工启动:
[root@node3 ~]# crs_start ora.node3.LISTENER_NODE3.lsnr -f
CRS-2527: Unable to start 'ora.LISTENER.lsnr' because it has a 'hard' dependency on 'ora.cluster_vip_net1.type'
CRS-2525: All instances of the resource 'ora.node1.vip' are already running; relocate is not allowed because the force option was not specified
CRS-2525: All instances of the resource 'ora.node2.vip' are already running; relocate is not allowed because the force option was not specified
CRS-0222: Resource 'ora.node3.LISTENER_NODE3.lsnr' has dependency error.
从以上日志可以看出,listener 在启动时,缺少vip的支持(node3 vip service)
[root@node3 ~]# crs_stat |grep vip
NAME=ora.node1.vip
TYPE=ora.cluster_vip_net1.type
NAME=ora.node2.vip
TYPE=ora.cluster_vip_net1.type
NAME=ora.scan1.vip
TYPE=ora.scan_vip.type
缺少node vip service!
添加vip service:
[root@node3 ~]# srvctl add -h
The SRVCTL add command adds the configuration and the Oracle Clusterware application to the OCR for the cluster database, named instances, named services, or for the named nodes.
Usage: srvctl add vip -n
[root@node1 ~]# cat /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.

PRCN-2049 : The network attributes specified (network number: 0, subnet: 192.168.8.0, adapters: eth0) conflict with an already registered network (network number: 1, subnet: 192.168.8.0, adapters: eth0)
[root@node3 ~]# srvctl add vip -n node3 -A 192.168.8.47/255.255.255.0/eth0 -k 1
[root@node3 ~]#
添加node3 vip service 成功!
[root@node3 ~]# crs_stat |grep vip
NAME=ora.node1.vip
TYPE=ora.cluster_vip_net1.type
NAME=ora.node2.vip
TYPE=ora.cluster_vip_net1.type

TYPE=ora.cluster_vip_net1.type
NAME=ora.scan1.vip
TYPE=ora.scan_vip.type
[root@node3 ~]#
启动ora.node3.LISTENER_NODE3.lsnr service:
[root@node3 ~]# crs_stat |grep lsn
NAME=ora.LISTENER.lsnr
NAME=ora.LISTENER_SCAN1.lsnr
NAME=ora.node1.LISTENER_NODE1.lsnr
NAME=ora.node2.LISTENER_NODE2.lsnr
NAME=ora.node3.LISTENER_NODE3.lsnr
[root@node3 ~]# crs_start -f ora.node3.LISTENER_NODE3.lsnr

4、添加Oracle 节点
CRS资源已经启动成功,但在node1 上添加 node3 的Oracle 节点时,报以下错误!
重新启动node的CRS service ,仍然不能解决,最后尝试在node2 上添加node3 的Oracle新节点,却成功(node1 不能添加,还是个不解之谜;可能是在添加CRS节点时是在node1上执行,添加出现了错误(在node3 运行root.sh时)导致node不能正常识别node3的新节点)!
node3 记录以下日志:
[root@node3 node3]# tail -f alertnode3.log
[gpnpd(7901)]CRS-2332:Error pushing GPnP profile to "mdns:service:gpnp._tcp.local.://node1:12802/agent=gpnpd,cname=node-cluster,host=node1,pid=3431/gpnpd h:node1 c:node-cluster".
