1）破坏前的ocr和votedisk信息检查检查ocr自动备份[root@rac1~]#ocrconfig-showbackuprac22013/10/1309:45:30/u01/grid/product/11.2.0/cdata/rac-cluster/backu


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

Device/File not configured


Device/File not configured


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]

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

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）
