在搭建 openGauss-1.0.0-CentOS-64bit主备机群的时候，执行：
gs_install -X /opt/software/openGauss/clusterconfig.xml
【遇到问题】：
…
[FAILURE] node2.localdomain:
Using omm:dbgrp to install database.

$GAUSSHOME points to /opt/gaussdb/app_0bd0ce80, no need to create symbolic link.

【分析问题】：
检查集群状态： gs_om -t status --detail
[ Cluster State ]
cluster_state : Degraded
redistributing : No
current_az : AZ_ALL
[ Datanode State ]
node node_ip instance state | node node_ip instance state
1 node1.localdomain 192.168.0.11 6001 /gaussdb/data/db1 P Primary Normal | 2 node2.localdomain 192.168.0.12 6002 /gaussdb/data/db1 S Standby Need repair(System)
发现node2节点 Need repair
【解决问题】
在node2节点上，执行gs_ctl build -D /gaussdb/data/db1 -b full
再次查看集群状态：
[omm@node1 openGauss]$ gs_om -t status --detail
[ Cluster State ]
cluster_state : Normal
redistributing : No
current_az : AZ_ALL
[ Datanode State ]
node node_ip instance state | node node_ip instance state
1 node1.localdomain 192.168.0.11 6001 /gaussdb/data/db1 P Primary Normal | 2 node2.localdomain 192.168.0.12 6002 /gaussdb/data/db1 S Standby Normal
[omm@node1 openGauss]$
Standby Normal，问题解决。
在此感谢@多米爸比的支持！
