11gR2 ocr votedisk的恢复测试

分类： Oracle

2017-08-31 10:43:00

先做一些检查：



1.检查ocr的完整性

root@oeltan1 ~]# su - grid
[grid@oeltan1 ~]$ cluvfy comp ocr -n all
[plain] view plain copy print?
  1. Verifying OCR integrity   
  2. Checking OCR integrity...  
  3. Checking the absence of a non-clustered configuration...  
  4. All nodes free of non-clustered, local-only configurations  
  5. ASM Running check passed. ASM is running on all specified nodes  
  6. Checking OCR config file "/etc/oracle/ocr.loc"...  
  7. OCR config file "/etc/oracle/ocr.loc" check successful  
  8. Disk group for ocr location "+CRS" available on all the nodes  
  9. Disk group for ocr location "+DATA1" available on all the nodes  
  10.   
  11. NOTE:   
  12. This check does not verify the integrity of the OCR contents. Execute 'ocrcheck' as a privileged user to verify the contents of OCR.  
  13. OCR integrity check passed  
  14. Verification of OCR integrity was successful.   


[grid@oeltan1 ~]$ ocrcheck
[plain] view plain copy print?
  1. Status of Oracle Cluster Registry is as follows :  
  2.          Version                  :          3

  23.   
  24.   
  25.          Logical corruption check bypassed due to non-privileged user  


2.检查votedisk



[grid@oeltan1 ~]$ crsctl query css votedisk
##  STATE    File Universal Id                File Name Disk group
--  -----    -----------------                --------- ---------
 1. ONLINE   2141c8c7d8904f89bfa45dbaecb827c5 (/dev/asm-diskb) [CRS]

Located 1 voting disk(s).

3看看磁盘使用的情况 

  1* select name,header_status,path from V$asm_disk
SQL> /

FRI_0001                       MEMBER       /dev/asm-diski
FRI_0002                       MEMBER       /dev/asm-diskj


做备份 


11g中votedisk不需要备份


1备份ASMspfile                                        

SQL> create pfile='/tmp/asm_pfile_0724.txt' from spfile    


2备份ocr

[root@oeltan1 ~]# ocrconfig -manualbackup

3检查备份：

[root@oeltan1 ~]# ocrconfig -showbackup
[plain] view plain copy print?

破坏掉3块CRS盘


开始搞破坏喽。。。


[root@oeltan2 ~]# dd if=/dev/zero of=/dev/asm-dskb bs=1024 count=1000
[root@oeltan2 ~]# dd if=/dev/zero of=/dev/asm-dskc bs=1024 count=1000
[root@oeltan2 ~]# dd if=/dev/zero of=/dev/asm-dskd bs=1024 count=1000

检查一下：
[root@oeltan1 ~]# ocrcheck
PROT-601: Failed to initialize ocrcheck
PROC-22: The OCR backend has an invalid format

开始还原：


1.强制停止CRS

[root@oeltan1 ~]# crsctl stop crs -f
CRS-2791: Starting shutdown of Oracle High Availability Services-managed resources on 'oeltan1'
CRS-4133: Oracle High Availability Services has been stopped.
上面这个时间有点长，10多分钟

节点2也要停

2.以独占模式启动：

[root@oeltan1 ~]# crsctl start crs -excl -nocrs
[plain] view plain copy print?
  1. CRS-4123: Oracle High Availability Services has been started.  
  2. CRS-2672: Attempting to start 'ora.mdnsd' on 'oeltan1'  
  3. CRS-2676: Start of 'ora.mdnsd' on 'oeltan1' succeeded  
  4. CRS-2672: Attempting to start 'ora.gpnpd' on 'oeltan1'  
  5. CRS-2676: Start of 'ora.gpnpd' on 'oeltan1' succeeded  
  6. CRS-2672: Attempting to start 'ora.cssdmonitor' on 'oeltan1'  
  7. CRS-2672: Attempting to start 'ora.gipcd' on 'oeltan1'  
  8. CRS-2676: Start of 'ora.cssdmonitor' on 'oeltan1' succeeded  
  9. CRS-2676: Start of 'ora.gipcd' on 'oeltan1' succeeded

  16. CRS-2681: Clean of 'ora.cluster_interconnect.haip' on 'oeltan1' succeeded  
  17. CRS-2672: Attempting to start 'ora.cluster_interconnect.haip' on 'oeltan1'  
  18. CRS-2676: Start of 'ora.ctssd' on 'oeltan1' succeeded  
  19. CRS-2676: Start of 'ora.cluster_interconnect.haip' on 'oeltan1' succeeded  
  20. CRS-2672: Attempting to start 'ora.asm' on 'oeltan1'  
  21. CRS-2676: Start of 'ora.asm' on 'oeltan1' succeeded  



3.创创建CRS磁盘组

[grid@oeltan1 ~]$ asmcmd
ASMCMD> ls
ASMCMD> 
[grid@oeltan1 ~]$ sqlplus / as sysasm


SQL*Plus: Release 11.2.0.3.0 Production on Fri Jul 26 09:33:13 2013


Copyright (c) 1982, 2011, Oracle.  All rights reserved

Connected to:
Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production

SQL> show parameter spfile

  2  attribute 'compatible.asm'='11.2.0.0.0','compatible.rdbms'='11.2.0.0.0';


Diskgroup created.

4.还愿spfile

SQL> create spfile='+CRSVOTE' from pfile='/tmp/asm_pfile_0724.txt';


File created.


ASMCMD> pwd  
+CRSVOTE/oeltan-cluster/ASMPARAMETERFILE
ASMCMD> ls
REGISTRY.253.821785057


5. 修改ocr.loc，节点2也要改。

[root@oeltan1 ~]# vi /etc/oracle/ocr.loc


#Device/file +DATA1 being deleted
ocrconfig_loc=+CRSVOTE
local_only=false


6.导入OCR

# ocrconfig -restore /apps/grid/gridhome/11.2.0/grid/cdata/oeltan-cluster/backup_20130723_111730.ocr


ASMCMD> pwd
+CRSVOTE/oeltan-cluster
ASMCMD> ls
ASMPARAMETERFILE/
OCRFILE/


检查OCR
[root@oeltan1 ~]# ocrcheck

7.修复VOTE  DISK

[root@oeltan1 ~]# crsctl query css votedisk
Located 0 voting disk(s).
[root@oeltan1 ~]# 
[root@oeltan1 ~]# crsctl replace votedisk +CRSVOTE
CRS-4602: Failed 27 to add voting file 66d2624128ee4fd2bf882a8a3d295a99.
CRS-4602: Failed 27 to add voting file 1d4cf4ec74794f05bfc8f3f452cddfaf.
CRS-4602: Failed 27 to add voting file 731c37abf7fa4fc0bf6219155cf0e7e0.
Failed to replace voting disk group with +CRSVOTE.
CRS-4000: Command Replace failed, or completed with errors.
[root@oeltan1 ~]# crsctl query css votedisk
Located 0 voting disk(s).
出现上面的错误，是因为asm_diskstring配置不正确：
检查一下：
SQL> show parameter asm


NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
asm_diskgroups                       string      CRSVOTE
asm_diskstring                       string
asm_power_limit                      integer     1
asm_preferred_read_failure_groups    string
修改
SQL> alter system set asm_diskstring='/dev/asm*' scope=both;
需要重启ASM
上述问题更详细的解决过程：http://blog.csdn.net/tanqingru/article/details/9493703

再次还愿votedisk


[root@oeltan1 ~]# crsctl replace votedisk +CRSVOTE
Successful addition of voting disk 54e90342890c4f58bf319f3c57c4acd7.
Successful addition of voting disk 5103d7e756f14f69bf3935ace34e5de7.

Successfully replaced voting disk group with +CRSVOTE.
CRS-4266: Voting file(s) successfully replaced
[root@oeltan1 ~]# crsctl  query css votedisk

 3. ONLINE   370645ed11324fe5bf99eac9bf5efb21 (/dev/asm-diskd) [CRSVOTE]

重启CRS

1.检查一下crs


[root@oeltan1 ~]# crsctl check crs
CRS-4638: Oracle High Availability Services is online
CRS-4535: Cannot communicate with Cluster Ready Services
CRS-4529: Cluster Synchronization Services is online
CRS-4534: Cannot communicate with Event Manager


2.正常重启一次

crsctl stop crs
crsctl start crs

节点2也启动：
[root@oeltan2 tmp]# crsctl start crs

3.检查一下crs


[root@oeltan1 ~]# crsctl check crs


CRS-4638: Oracle High Availability Services is online
CRS-4537: Cluster Ready Services is online
CRS-4529: Cluster Synchronization Services is online
CRS-4533: Event Manager is online

恢复后检查

1最后进行检查：
