【转】OCR和VOTING DISK的MIRROR DISK的添加和删除及备份

一、添加OCR

1) 停止crs，分别在所有节点执行
# /u01/app/oracle/product/10.2.0/crs_1/bin/crsctl stop crs
Stopping resources.
Successfully stopped CRS resources
Stopping CSSD.
Shutting down CSS daemon.
Shutdown request successfully issued.

2) 导出ocr数据
# /u01/app/oracle/product/10.2.0/crs_1/bin/ocrconfig -export /tmp/ocr.bak

3) 编辑ora.loc文件，增加镜像ocrmirrorconfig_loc，所有需要增加ocr文件的节点都需要执行该操作
# vi /etc/oracle/ocr.loc
ocrconfig_loc=/ocfs/clusterware/ocr
ocrmirrorconfig_loc=/ocfs/clusterware/ocr2
local_only=FALSE

4) 导入ocr数据
# /u01/app/oracle/product/10.2.0/crs_1/bin/ocrconfig -import /tmp/ocr.bak

5) 检查添加后的结果
# /u01/app/oracle/product/10.2.0/crs_1/bin/ocrcheck
Status of Oracle Cluster Registry is as follows :
         Version                  :          2
         Total space (kbytes)     :     262144
         Used space (kbytes)      :       3824
         Available space (kbytes) :     258320
         ID                       :   93257176
         Device/File Name         : /ocfs/clusterware/ocr
                                    Device/File integrity check succeeded
         Device/File Name         : /ocfs/clusterware/ocr2
                                    Device/File integrity check succeeded

         Cluster registry integrity check succeeded

6) 启动crs，可以用crsctl start crs
7) 检查crs状态crsctl check crs

备份，ocr是oracle自动备份每4小时一次：
Ocrconfig –showbackup

二、删除mirror比较简单，关闭crs，去掉/注释掉ocrmirrorconfig_loc这行，然后删除相应的设备/文件就可以了。

三、添加Voting Disk

1) 查看crs状态
# /u01/app/oracle/product/10.2.0/crs_1/bin/crsctl check crs
CSS appears healthy
CRS appears healthy
EVM appears healthy

# /u01/app/oracle/product/10.2.0/crs_1/bin/crsctl query css votedisk
0.     0    /ocfs/clusterware/votingdisk

located 1 votedisk(s).

2) 添加votedisk
# /u01/app/oracle/product/10.2.0/crs_1/bin/crsctl add css votedisk /ocfs/clusterware/votingdisk2 -force
Now formatting voting disk: /ocfs/clusterware/votingdisk2
successful addition of votedisk /ocfs/clusterware/votingdisk2.

# /u01/app/oracle/product/10.2.0/crs_1/bin/crsctl query css votedisk
0.     0    /ocfs/clusterware/votingdisk
1.     0    /ocfs/clusterware/votingdisk2

located 2 votedisk(s).

四、voting disk 的删除，同上，同样需要 -force参数

# /u01/app/oracle/product/10.2.0/crs_1/bin/crsctl delete css votedisk /ocfs/clusterware/votingdisk2 -force
successful deletion of votedisk /ocfs/clusterware/votingdisk2.

平时备份VD，可直接dd完成。
$ dd if=/dev/vg01/rora_vote of=/orabackup/rora_vote_1
