1）破坏前的ocr和votedisk信息检查
检查ocr自动备份
[root@rac1 ~]# ocrconfig -showbackup
rac2 2013/10/13 09:45:30 /u01/grid/product/11.2.0/cdata/rac-cluster/backup00.ocr
rac2 2013/10/13 05:45:29 /u01/grid/product/11.2.0/cdata/rac-cluster/backup01.ocr
rac2 2013/10/13 01:45:28 /u01/grid/product/11.2.0/cdata/rac-cluster/backup02.ocr
rac2 2013/10/12 01:45:26 /u01/grid/product/11.2.0/cdata/rac-cluster/day.ocr
rac2 2013/09/28 02:55:56 /u01/grid/product/11.2.0/cdata/rac-cluster/week.ocr
PROT-25: Manual backups for the Oracle Cluster Registry are not available
这里有一个PROT-25的提示信息，手工备份时无效，所以破坏后直接用自动备份恢复
检查ocr磁盘信息
[root@rac1 ~]# ocrcheck
Status of Oracle Cluster Registry is as follows :
Version : 3
Total space (kbytes) : 262120
Used space (kbytes) : 2720
Available space (kbytes) : 259400

Device/File Name : +OCRDATA
Device/File integrity check succeeded
Device/File not configured
Device/File not configured

查看votedisk磁盘信息
[root@rac1 ~]# crsctl query css votedisk
## STATE File Universal Id File Name Disk group
-- ----- ----------------- --------- ---------
1. ONLINE 5c190e6ab4c04facbfdd4ca0e836a798 (ORCL:OCR1) [OCRDATA]
2. ONLINE abcc18afe6214fbcbfa02fad1c41b21b (ORCL:OCR2) [OCRDATA]
3. ONLINE 31e0a9df91514f73bf50a4e0a344af3d (ORCL:OCR3) [OCRDATA]
Located 3 voting disk(s).
可以看到OCR磁盘和votedisk都通过ASM OCRDATA磁盘组管理
查看ASM磁盘组 OCRDATA信息，我的OCRDATA磁盘组是有OCR1-3组成所以直接通过下列命令查询
[root@rac1 ~]# /etc/init.d/oracleasm querydisk -d OCR1
Disk "OCR1" is a valid ASM disk on device /dev/sda1[8,1]
[root@rac1 ~]# /etc/init.d/oracleasm querydisk -d OCR2
Disk "OCR2" is a valid ASM disk on device /dev/sdh1[8,113]
[root@rac1 ~]# /etc/init.d/oracleasm querydisk -d OCR3
Disk "OCR3" is a valid ASM disk on device /dev/sdb1[8,17]
由于ASM参数文件保存在OCRDATA下，所以对备份一份spfile
SQL> show parameter spfile;
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
spfile string +OCRDATA/rac-cluster/asmparame
terfile/registry.253.825083547
SQL> create pfile='/tmp/asmbak.ora' from spfile; --备份到/tmp/asmbak.ora
File created.
2）模拟损坏
使用dd命令破坏这几个磁盘,
[root@rac1 ~]# dd if=/dev/zero of=/dev/sda1 bs=1M count=10
10+0 records in
10+0 records out
10485760 bytes (10 MB) copied, 0.005454 seconds, 1.9 GB/s
[root@rac1 ~]# dd if=/dev/zero of=/dev/sdh1 bs=1M count=10
10+0 records in
10+0 records out
10485760 bytes (10 MB) copied, 0.00603 seconds, 1.7 GB/s
破坏后执行下面命令，发现各节点服务一切正常
[root@rac1 ~]# crs_stat -t

上面log写的很清楚，在3快磁盘中只有1块可用，voting file 0，voting file 1 notfound，根据上面的log找到OCR3是可以用的，通过oracleasmdisk命令可以找到我们损坏的磁盘除了OCR3剩下
的两块就是OCR1 和OCR2了
[root@rac1 ~]# /etc/init.d/oracleasm listdisks

4）实施恢复
先重启一下操作系统
[root@rac1 ~]# reboot
重启完成后发现ASM磁盘OCR1和OCR2已经找不到了
[root@rac1 ~]# /etc/init.d/oracleasm listdisks

由于之前我只破坏10m的内容，这里我将这两个磁盘格式化后重新分区（一定要注意是哪两块磁盘，错了就麻烦了）

节点一已经恢复了，节点2重启下crs服务就可以了
至此COR和Votedisk损坏恢复完成，在这个实验中我犯了一个小错误，由于我的环境是通过Linux下的虚拟化搭建的，通过iscsi-target做的共享磁盘，我的rac没有修改udev设备，
在重启电脑后盘符的顺序改变了，不小心将数据磁盘给格式化了，还好做了冗余，之后又做了恢复。
