11.2.0.1.0 RAC啟動使用root使用者啟動crs報錯CRS-4535

1.故障描述：

11.2.0.1.0 RAC啟動使用root使用者啟動crs報錯

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使用者執行./crsctl   start   crs報錯：

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跑指令碼的時也遇到了，是11.2.0.1的一個典型的bug

再執行一次

[root@Rac01 ~]# cd /u01/app/12.1.0/grid/bin/

[root@Rac01 bin]# ./crsctl  start crs

同時另開一個視窗，執行語句，直到視窗卡住

[root@Rac01 bin]# /bin/dd if=/var/tmp/.oracle/npohasd of=/dev/null bs=1024 count=1

3.故障解決

[root@Rac01 bin]# ./crsctl  start crs

CRS-4123: Oracle High Availability Services has been started.
