crs_stop -all 命令后遇到 UNKNOWN
RAC中执行crs_stop -all后提示一些服务停不了，再用crs_stat -t查看状态的时候，停不掉的服务会显示状态是UNKNOWN，
服务在UNKNOWN状态下用 crs_start 不能启动服务
例如：
[oracle@rac1 ~]$ crs_stop -all

此时crs_stat -t的状态还是有很多的UNKNOWN
（烦、烦、烦，rac中真奇怪，正常启动关闭服务时，
状态只有online和offline两种（启动与未启动），结果RAC中给你来了个UNKNOWN）：

显示数据库已经连接不上；
此时可有两种方法来解决：
方法一：先禁用crs服务，后启用crs服务
（相当于从新启动系统，因为crs是随系统自动启动的），需要在两台节点上都执行；
具体步骤：
节点1：
1、[root@rac1 ~]# /etc/init.d/init.crs stop
Shutting down Oracle Cluster Ready Services (CRS):
Stopping resources.
Successfully stopped CRS resources
Stopping CSSD.
Shutting down CSS daemon.
Shutdown request successfully issued.
Shutdown has begun. The daemons should exit soon.
2、[root@rac1 ~]# su - oracle
[oracle@rac1 ~]$ crs_stat -t
CRS-0184: Cannot communicate with the CRS daemon.
3、[oracle@rac1 ~]$ exit
logout
[root@rac1 ~]# /etc/init.d/init.crs start
Startup will be queued to init within 90 seconds.
4、[root@rac1 ~]# su - oracle
[oracle@rac1 ~]$ crs_stat -t

总结：在rac环境中如果使用crs_stop -all去停rac服务时，很有可能会出现crs中的一些服务的状态是UNKNOWN，这时我们可以采用两种方法去重新启动crs服务：
1：转换到root用户下用/etc/init.d/init.crs stop先禁用crs，然后再用/etc/init.d/init.crs start去启用crs，启用crs后会自动启动crs的一系列服务，注意此种方法需要在两台节点上都执行；
2：是用crs_stop -f 参数把crs中状态是UNKNOWN的服务关掉，然后再用crs_start -f （加一个-f的参数）启动所有的服务就可以。参考：http://www.rachelp.nl/index_kb.php?menu=articles&actie=show&id=31
要分别在两个节点上执行；
在启动的过程中最好检测着crs、ASM和数据库的日志：
crs日志：
[oracle@rac1 ~]$ tail -f /u01/app/oracle/product/10.2.0/crs_1/log/rac1/alertrac1.log
[oracle@rac2 ~]$ tail -f /u01/app/oracle/product/10.2.0/crs_1/log/rac2/alertrac2.log
ASM日志：
[oracle@rac1 ~]$ tail -f /u01/app/oracle/admin/+ASM/bdump/alert_+ASM1.log
[oracle@rac2 ~]$ tail -f /u01/app/oracle/admin/+ASM/bdump/alert_+ASM2.log
数据库日志：
[oracle@rac1 ~]$ tail -f /u01/app/oracle/admin/ora9i/bdump/alert_ora9i1.log
[oracle@rac2 ~]$ tail -f /u01/app/oracle/admin/ora9i/bdump/alert_ora9i2.log
