环境介绍
在主安装节点执行root脚本，查看日志存在以下失败信息
[root@orcl1 ~]# tail -100f /u01/app/grid_home/install/root_orcl1_2021-02-04_16-43-26.log
Performing root user operation for Oracle 11g
The following environment variables are set as:

错误特征
除了上述的错误以外，可以查看一下两个节点$GI_HOME/lib目录下库的数量对比
[root@orcl1 ~]# ls /u01/app/grid_home/lib/ | wc -l
210
[root@orcl2 ~]# ls /u01/app/grid_home/lib/ | wc -l
207
#因为是第二次安装，之前一次安装是成功的所以对比了一下安装成功库文件的数量
[root@orcl1 ~]# ls /u01/app/grid_home/lib/ | wc -l
215 -> 这个是安装成功的数量
错误原因
11.2版本bug，在12.1该bug已经被修复
GI的安装或升级完成，OUI要求运行root.sh或rootupgrade.sh脚本，可能出现在第一个节点上成功完成，但是根脚本在一个或多个远程节点上失败。或者两个节点都无法运行成功。在12.1.0.2中引入了Rapid Trans，以改善在安装Grid Infrastructure（GI）期间向远程节点的文件传输，解决前者的问题。后者问题暂时无法确定，只能重装。
如果安装过程出现安装节点成功但是其他节点失败的问题，可以将安装节点$GI_HOME/lib目录下库传入到其他节点重新执行root脚本接口
