1.故障描述： 11.2.0.1.0 RAC启动使用root用户启动crs报错 CRS-4535: Cannot communicate with Cluster Ready Services CRS-4000: Command Status failed, or completed with errors. [grid@Rac01 bin]$ ./crsctl  stat res -t CRS-4535: Cannot communicate with Cluster Ready Services CRS-4000: Command Status failed, or completed with errors. 使用root用户执行./crsctl   start   crs报错： CRS-4124: Oracle High Availability Services startup failed. CRS-4000: Command Start failed, or completed with errors. 2.故障分析 11.2.0.1的建GI跑脚本的时也遇到了，是11.2.0.1的一个典型的bug 再运行一次 [root@Rac01 ~]# cd /u01/app/12.1.0/grid/bin/ [root@Rac01 bin]# ./crsctl  start crs 同时另开一个窗口，执行语句，直到窗口卡住 [root@Rac01 bin]# /bin/dd if=/var/tmp/.oracle/npohasd of=/dev/null bs=1024 count=1 3.故障解决 [root@Rac01 bin]# ./crsctl  start crs CRS-4123: Oracle High Availability Services has been started.
