使用root用戶執(zhí)行./crsctl start crs報(bào)錯(cuò)：

CRS-4000: Command Start failed, or completed with errors.

2.故障分析

11.2.0.1的建GI跑腳本的時(shí)也遇到了，是11.2.0.1的一個(gè)典型的bug

再運(yùn)行一次

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

[root@Rac01 bin]# ./crsctl start crs

同時(shí)另開一個(gè)窗口，執(zhí)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.
