环境：11.2.0.3 rac primary+rac standby  
  
生产库rac standby的node1节点CRS自动关闭问题  
  
\--EM报警

登陆到该库node1，发现CRS进程已经关闭

ps -ef|grep crs --同样没有crs进程  
  
试着启动crs进程，但是无法启动

CRS-4535: Cannot communicate with Cluster Ready Services <<----CRS没有起来

在grid用户下查看crs进程日志

通过日志，可以看出是CRS磁盘组有问题  
  
也确实如此，没有挂载CRS磁盘组

启动CRS  
但是常用的start crs命令执行不成功  
\# /app/grid/bin/crsctl start crs

使用该命令启动成功

解决路线图:  
crsd\_log-->asm\_instance\_alert\_log-->mount crs diskgroup -->start crs  
  
虽然node1的CRS恢复正常，但CRS磁盘组会被强制dismount的原因还没找到，找到后会贴在这里。
