今天在虚拟机上启动rac,发现有一个节点怎么都起不了。另外一个节点没问题。
SQL> startup nomount
ORA-29702: error occurred in Cluster Group Service operation
尝试使用crs_stat查看crs的组件状态，也报错了。
-bash-4.1$ crs_stat -t
CRS-0184: Cannot communicate with the CRS daemon.
查看alert日志，发现在最后是因为29702的错误导致的。
SMON started with pid=20, OS id=12344

USER (ospid: 12242): terminating the instance due to error 29702
Instance terminated by USER, pid = 12242
对于这个错误，oracle给出的解释如下。
-bash-4.1$ oerr ora 29702
29702, 00000, "error occurred in Cluster Group Service operation"
// *Cause: An unexpected error occurred while performing a CGS operation.
// *Action: Verify that the LMON process is still active.
// Check the Oracle LMON trace files for errors.
// Also, check the related CSS trace file for errors.
查看lmon的日志如下：

对于该节点，使用crs_stat，crsctl的操作都无济于事。
-bash-4.1$ crsctl check crs
CRS-4638: Oracle High Availability Services is online

查看进程，确实都起来了。
-bash-4.1$ ps -ef|grep d.bin

使用root用户来停掉crs。但是报了错。
root
[root@rac1 bin]# ./crsctl disable crs
CRS-4621: Oracle High Availability Services autostart is disabled.
[root@rac1 bin]# ./crsctl stop crs
CRS-2796: The command may not proceed when Cluster Ready Services is not running
CRS-4687: Shutdown command has completed with errors.
CRS-4000: Command Stop failed, or completed with errors.
再次尝试启动，也是报错。
[root@rac1 bin]# ./crsctl enable crs
CRS-4622: Oracle High Availability Services autostart is enabled.
[root@rac1 bin]# ./crsctl start crs
CRS-4640: Oracle High Availability Services is already active
CRS-4000: Command Start failed, or completed with errors.
最后看到mos上有一个workaround，可以手动Kill掉那些crs的进程。当然了，在正式环境中还是得把psu打上。
[root@rac1 bin]# ps -fea | grep ohasd.bin | grep -v grep

[root@rac1 bin]# ps -fea | grep crsd.bin | grep -v grep
[root@rac1 bin]# kill -9 2103 2333 2309 2320
再次尝试启动crs
[root@rac1 bin]# ./crsctl start crs
CRS-4123: Oracle High Availability Services has been started.
[root@rac1 bin]# ./crs_stat -t
CRS-0184: Cannot communicate with the CRS daemon.
启动的时候有些慢，稍等一下，直接自己来启库了。这次起库就没有问题了。

查看crs的状态，该起的都起了。两个节点创建了一个小表做测试，没有问题了。那个workaround的细节可以从MOS文档 ID 1233580.1里面查看。
