RAC 11gR2模拟OCR和Votedisk损坏恢复过程

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

ID : 2026562699

Device/File Name : +OCRDATA

Device/File integrity check succeeded

Device/File not configured

Cluster registry integrity check succeeded

Logical corruption check succeeded

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]

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

3）故障定位

在此启动发现已经无法正常启动了，跟踪alter日志，（由于系统日志没有发现什么重要信息，这里就没贴出来）

发现服务都无法启动，根据上面的提示检查ocssd.log日志文件

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

DATA1

DATA2

DATA3

FRA2

OCR1

OCR2

OCR3

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。
