1、集群没有启动起来，首先查看了一下grid的日志，日志保存在$GRID_HOME/log/<节点名称> 目录下，文件的名字是alert<节点名称>.log
例如我的日志文件就是/g01/11ggrid/app/11.2.0/grid/log/orcl1/alertorcl1.log
2、查看日志文件，在日志文件里我们发现了发下错误
-
2014-09-10 15:24:09.169
-
[ohasd(2450)]CRS-0704:Oracle High Availability Service aborted due to Oracle Local Registry error [PROCL-26: Error while accessing the physical storage Operating System error [No such file or directory] [2]]. Details at (:OHAS00106:) in /g01/11ggrid/app/11.2.0/grid/log/orcl1/ohasd/ohasd.log.
-
[client(2465)]CRS-10001:CRS-10132: No msg for has:crs-10132 [10][60]
3、于是查看ohasd.log文件，有如下错误提示
-

4、问题比较明显是orcl1.lor文件找不到，到目录下面查看果然没有这个文件，于是开始查找资料恢复。
首先确定原来orcl1.lor文件的配置信息
-
[root@orcl1 orcl1]# ocrcheck -config -local
-
Oracle Local Registry configuration is :
-
Device/File Name : /g01/11ggrid/app/11.2.0/grid/cdata/orcl1.olr
5、使用touch命令创建文件
-
[root@orcl1 orcl1]# touch /g01/11ggrid/app/11.2.0/grid/cdata/orcl1.olr
-
[root@orcl1 orcl1]# cd ..
-
[root@orcl1 cdata]# ll
-
total 12
-
drwxr-xr-x 2 grid oinstall 4096 Sep 4 12:11 localhost
-
drwxr-xr-x 2 grid oinstall 4096 Sep 4 12:49 orcl1
-
-rw-r--r-- 1 root root 0 Sep 10 22:33 orcl1.olr
-
drwxrwxr-x 2 grid oinstall 4096 Sep 4 12:11 orcl-cluster
6、恢复olr文件内容。默认olr文件会在目录下的<节点名>文件夹中，保存一下备份
-
[root@orcl1 cdata]# ocrconfig -local -restore ./orcl1/backup_20140904_124926.olr
-
[root@orcl1 cdata]# ll
-
total 6636
-
drwxr-xr-x 2 grid oinstall 4096 Sep 4 12:11 localhost
-
drwxr-xr-x 2 grid oinstall 4096 Sep 4 12:49 orcl1
-
-rw-r--r-- 1 root root 272756736 Sep 10 22:34 orcl1.olr
-
drwxrwxr-x 2 grid oinstall 4096 Sep 4 12:11 orcl-cluster
7、启动集群
-
[root@orcl1 cdata]# crsctl start crs
-
[root@orcl1 cdata]# crsctl stat res -t
