安装CRS-Failureat final check of Oracle CRS stack错误处理
2.9. 运行脚本（orainstRoot.Sh 和 root.Sh）
在每个节点依次执行orainstRoot.sh脚本（先执行安装CRS软件的节点）：
[oracle@rac1~]$ su - root
Password:
[root@rac1~]# /u01/app/oracle/oraInventory/orainstRoot.sh
Changingpermissions of /u01/app/oracle/oraInventory to 770.
Changinggroupname of /u01/app/oracle/oraInventory to oinstall.
Theexecution of the script is complete
依次执行 root.sh脚本（先执行你的CRS安装软件的那个节点）
[root@rac1~]# /u01/app/oracle/product/crs/root.sh

再在另外个节点执行如下：

安装Cluster的过程中第一个节点顺利通过，第二个节点出现了该错误，查了下错误，怀疑是虚拟机的共享磁盘设置的不对，对共享磁盘添加以下参数解决该问题：
最后添加这个
disk.locking = "false"
diskLib.dataCacheMaxSize = "0"
diskLib.dataCacheMaxReadAheadSize = "0"
diskLib.DataCacheMinReadAheadSize = "0"
diskLib.dataCachePageSize = "4096"
diskLib.maxUnsyncedWrites = "0"
