Oralce 11g RAC OCR和VOTEDISK 迁移

1、新建一个磁盘组+NEW

Create diskgroup CRS NORMAL REDUNDANCY

FAILGROUP CRS_0000 disk '/dev/asm-orctest1'

FAILGROUP CRS_0001 disk '/dev/asm-orctest2'

FAILGROUP CRS_0002 disk '/dev/asm-orctest3'

ATTRIBUTE 'compatible.asm' = '11.2';

2、查看ocr备份

[root@rac02 bin]# ./ocrconfig -manualbackup

ocrconfig -showbackup

[root@rac02 bin]# ./ocrconfig -showbackup manual

rac01    2017/08/03 06:47:10    /u01/11.2.0/grid/cdata/rac-cluster/backup_20170803_064710.ocr

rac02    2017/08/01 02:32:01    /u01/11.2.0/grid/cdata/rac-cluster/backup_20170801_023201.ocr

2、2个节点停止集群并修改配置文件(更改里面的磁盘组名字为新建的磁盘组)

./crsctl stop crs

vi /etc/Oracle/ocr.loc

3、启动一个节点到独占模式并确认磁盘组+NEW是否mount，如没有，手动mount。

crsctl start crs -excl -nocrs

SQL> select  GROUP_NUMBER, NAME,STATE from  v$asm_diskgroup;

GROUP_NUMBER NAME                          STATE

------------ ------------------------------ -----------

1 ASM_DATA1                      MOUNTED

2 ASM_FL                        MOUNTED

3 CRS                            MOUNTED

4 DATA                          MOUNTED

4、使用OCR备份恢复OCR到新的磁盘组(注意提前更改ocr.loc)

#./ocrconfig -restore  /u01/11.2.0/grid/cdata/rac-cluster/backup_20170801_023201.ocr

[root@rac02 bin]# ./ocrconfig -manualbackup

rac01    2017/08/03 06:47:10    /u01/11.2.0/grid/cdata/rac-cluster/backup_20170803_064710.ocr

rac02    2017/08/01 02:32:01    /u01/11.2.0/grid/cdata/rac-cluster/backup_20170801_023201.ocr

5、恢复votedisk

[root@rac02 bin]# ./crsctl replace votedisk  +CRS

[root@rac02 bin]# ./ocrconfig -restore  /u01/11.2.0/grid/cdata/rac-cluster/backup_20170801_023201.ocr

[root@rac02 bin]# ./crsctl replace votedisk  +CRS

Successful addition of voting disk 99fc4fb627ab4ffabfa4819288ef362d.

Successful addition of voting disk 69c39aef708f4f0abf39c97b4c55dcea.

检查

ocrcheck---------------------------------------------检查结果未变化

crsctl query css votedisk

[root@rac02 bin]# ./ocrcheck

6、删除掉原来

./ocrconfig -delete  +DATA

然后重启集群
