进行节点信息更新的时候报错了：
[grid@rac2 bin]$ ./runInstaller -updateNodeList ORACLE_HOME=/u01/app/11.2.0.1/grid/ "CLUSTER_NODES={rac2}" CRS=TRUE -silent
Starting Oracle Universal Installer...
Checking swap space: must be greater than 500 MB. Actual 1858 MB Passed
The inventory pointer is located at /etc/oraInst.loc
The inventory is located at /u01/app/oraInventory
The Oracle home '/u01/app/11.2.0.1/grid/' could not be updated as it does not exist.
'UpdateNodeList' failed.
[grid@rac2 ~]$ echo $ORACLE_HOME
/u01/app/11.2.0.1/grid
[grid@rac2 ~]$ cd /u01/app/11.2.0.1/grid
[grid@rac2 grid]$ pwd
/u01/app/11.2.0.1/grid
[grid@rac2 grid]$
而这个ORACLE_HOME是存在的。
由于找不到原因，所以继续下一步检查添加节点：
cluvfy stage -pre nodeadd -n rac1 -verbose
结果报错：
ERROR:
PRVF-7593 : CRS is not found to be installed on node "rac2"
Verification cannot proceed
但是检查：
