删掉了$CRS_HOME/log/$HOSTNAME/下的所有日志文件和目录,于是has启不来了,单步执行:

sh -x /etc/init/ohasd
strace -p ohasd的pid
查看/var/log/messages,$ORACLE_HOME/log/$HOSTNAME/alert_$HOSTNAME.log,发现其步骤如下:
检查/opt/crs/product/bin/crsctl.bin文件:
进入目录:/var/tmp/.oracle 建立socket文件;
进入目录:/etc/oracle/
读取目录:
/opt/crs/product/log/MySQL-1/ohasd
写入文件:ohasdOUT.log
读取:
/opt/crs/product/crs/mesg/crsus.msb
执行:
/opt/crs/product/crs/install/s_crsconfig_mysql-1_env.txt
进入/opt/crs/product/log/mysql-1/agent/
写日志,日志目录如下:

笔记一下,防止再次发生;
另磁盘的检查超时也可能导致RAC启动不了,报:

建议临时解决办法:修改启动的超时时间:
crsctl modify resource "ora.cssd" -attr "START_TIMEOUT=1200" -init
