11.2.0.1的建GI跑腳本的時也遇到了，是11.2.0.1的一個典型的bug

再運行一次

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

[root@Rac01 bin]# ./crsctl  start crs

同時另開一個窗口，執行語句，直到窗口卡住

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

3.故障解決

[root@Rac01 bin]# ./crsctl  start crs

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