环境:RHEL 5.7 + Oracle 10.2.0.5 RAC

很多年前的一套测试环境,今天发现集群无法启动。手工尝试启动crs,集群日志也无任何输出。进一步检查集群配置:

[oracle@rac1-server rac1-server]$ ocrcheck
Status of Oracle Cluster Registry is as follows :
         Version                  :          2
         Total space (kbytes)     :      96144
         Used space (kbytes)      :       3852
         Available space (kbytes) :      92292
         ID                       : 1953645605
         Device/File Name         : /dev/raw/raw14
                                    Device/File integrity check succeeded
         Device/File Name         : /dev/raw/raw15
                                    Device/File integrity check succeeded

         Cluster registry integrity check succeeded

[oracle@rac1-server rac1-server]$ crsctl query css votedisk
 0.     0    jy2

located 1 votedisk(s).

确认Votedisk 存在问题,这个jy2不知道是怎么来的,反正是没有有效的votedisk,根据实际环境,我这里尝试加入合法的votedisk后恢复正常:

[root@rac1-server ~]# /s01/oracle/product/10.2.0/crs_1/bin/crsctl add css votedisk /dev/raw/raw11
Cluster is not in a ready state for online disk addition
[root@rac1-server ~]# /s01/oracle/product/10.2.0/crs_1/bin/crsctl add css votedisk /dev/raw/raw11 -f
unrecognized parameter -f.
[root@rac1-server ~]# /s01/oracle/product/10.2.0/crs_1/bin/crsctl add css votedisk /dev/raw/raw11 -force
Now formatting voting disk: /dev/raw/raw11
successful addition of votedisk /dev/raw/raw11.
[root@rac1-server ~]#
[root@rac1-server ~]# /s01/oracle/product/10.2.0/crs_1/bin/crsctl add css votedisk /dev/raw/raw12 -force
Now formatting voting disk: /dev/raw/raw12
successful addition of votedisk /dev/raw/raw12.
[root@rac1-server ~]# 
[root@rac1-server ~]# /s01/oracle/product/10.2.0/crs_1/bin/crsctl add css votedisk /dev/raw/raw13 -force
Now formatting voting disk: /dev/raw/raw13
Write failed: Broken pipe

因为我测试环境是ssh跳转的,会话断开,再次登陆查询:

[oracle@rac1-server ~]$ crsctl query css votedisk
 0.     0    /dev/raw/raw13
 1.     0    /dev/raw/raw11
 2.     0    /dev/raw/raw12
 3.     0    /dev/raw/raw13

发现有两个/dev/raw/raw13,尝试删除:

[root@rac1-server ~]# /s01/oracle/product/10.2.0/crs_1/bin/crsctl delete css votedisk /dev/raw/raw13 -force
successful deletion of votedisk /dev/raw/raw13.
[root@rac1-server ~]# /s01/oracle/product/10.2.0/crs_1/bin/crsctl query css votedisk
 0.     0    /dev/raw/raw11
 1.     0    /dev/raw/raw12
 2.     0    /dev/raw/raw13

located 3 votedisk(s).
[root@rac1-server ~]# /s01/oracle/product/10.2.0/crs_1/bin/crsctl delete css votedisk /dev/raw/raw13 -force
successful deletion of votedisk /dev/raw/raw13.
[root@rac1-server ~]# /s01/oracle/product/10.2.0/crs_1/bin/crsctl query css votedisk
 0.     0    /dev/raw/raw11
 1.     0    /dev/raw/raw12

located 2 votedisk(s).
[root@rac1-server ~]# /s01/oracle/product/10.2.0/crs_1/bin/crsctl add css votedisk /dev/raw/raw13 -force
Now formatting voting disk: /dev/raw/raw13
Write failed: Broken pipe

[root@rac1-server ~]# /s01/oracle/product/10.2.0/crs_1/bin/crsctl query css votedisk
 0.     0    /dev/raw/raw13
 1.     0    /dev/raw/raw11
 2.     0    /dev/raw/raw12

不确认这里Write failed: Broken pipe会不会有潜在影响,实际我查询和使用都是正常的。
再次尝试启动crs可以成功。
从集群日志中可以看到正常使用了我们加进去的votedisk:

最后检查下集群状态确认正常:
