用ASMCMD的md_backup命令备份磁盘组，顺便查看该磁盘组里都存放什么。
[root@12crac2 ~]# su - grid[grid@12crac2 ~]$ asmcmd -p ASMCMD [+] > md_backup /home/grid/ocrvote.bak -G RACCRSDisk group metadata to be backed up: RACCRSCurrent alias directory path: scan12cCurrent alias directory path: ASMCurrent alias directory path: _MGMTDB/CONTROLFILECurrent alias directory path: _MGMTDB/TEMPFILECurrent alias directory path: ASM/PASSWORDCurrent alias directory path: _MGMTDB/ONLINELOGCurrent alias directory path: _MGMTDBCurrent alias directory path: scan12c/OCRFILECurrent alias directory path: _MGMTDB/DATAFILECurrent alias directory path: scan12c/ASMPARAMETERFILECurrent alias directory path: _MGMTDB/PARAMETERFILE-- 从这里可以看出,在Oracle 12c RAC中，存放ocr的磁盘组里多了不少文件，有_MGMTDB相关文件以及ASM的PASSWORD。下面是11g RAC中存放OCR的磁盘组内容ASMCMD [+] > md_backup /home/grid/ocrvote.bak -G hk_crsDisk group metadata to be backed up: HK_CRSCurrent alias directory path: racscan/OCRFILECurrent alias directory path: racscanCurrent alias directory path: racscan/ASMPARAMETERFILE
也可以导出ocr的内容
[root@12crac1 bin]# ./ocrconfig -export /home/grid/ocr.bak
以下方式都无法删除当前使用的ocr内容
ASMCMD [+] > rm -rf /raccrs/scan12c/ocrfile ORA-29261: bad argument ORA-15178: directory 'ocrfile' is not empty; cannot drop this directory ORA-15028: ASM file '+RACCRS.255.819592481' not dropped; currently being accessed ORA-06512: at line 4 (DBD ERROR: OCIStmtExecute)ASMCMD [+] > cd /raccrs/scan12c/ocrfile ASMCMD [+raccrs/scan12c/ocrfile] > ls REGISTRY.255.819592481ASMCMD [+raccrs/scan12c/ocrfile] > rm -rf REGISTRY.255.819592481ORA-15032: not all alterations performed ORA-15028: ASM file '+raccrs/scan12c/ocrfile/REGISTRY.255.819592481' not dropped; currently being accessed (DBD ERROR: OCIStmtExecute)
那我们可以破坏存放ocr的设备文件
[root@12crac1 bin]# dd if=/dev/zero of=/dev/sdg bs=1024k count=11+0 records in1+0 records out1048576 bytes (1.0 MB) copied, 0.00335689 s, 312 MB/s
然后停止集群：
[root@12crac1 bin]# ./crsctl stop has [root@12crac2 bin]# ./crsctl stop has -f
或crsctl stop crs [-f]也可以
尝试启动clusterware，发现clusterware无法正常启动

– 我们可以看出表决磁盘无法找到等报错信息。
下面将集群关闭，尝试恢复。
[root@12crac1 bin]# ./crsctl stop has -f
ocr和vote disk损坏恢复步骤大致如下：
1）停止所有节点clusterware
# crsctl stop crs
# crsctl stop crs -f
2）以root用户在其中一个节点度扎模式启动clusterware
# crsctl start crs -excl -nocrs
备注：如果发现crsd在运行，那么通过如下命令将之停止。
# crsctl stop resource ora.crsd -init
3）创建新的存放ocr和vote disk的磁盘组，磁盘组名和原有的一致(如果想改变位置，需修改/etc/oracle/ocr.loc文件)
备注：如发现无法创建等情况，可以采用如下删除磁盘组等排错思路
SQL> drop diskgroup disk_group_name force including contents;
4）还原ocr，并检查
# ocrconfig -restore file_name
# ocrcheck
5）恢复表决磁盘，并检查
# crsctl replace votedisk +asm_disk_group
# crsctl query css votedisk
6）停止独占模式运行的clusterware
# crsctl stop crs -f
7）所有节点正常启动clusterware
# crsctl start crs
8）CVU验证所有RAC节点OCR的完整性
$ cluvfy comp ocr -n all -verbose

在这里我们会发现mgmtdb没有正常启动，手动尝试启动，会遇到问题。
[grid@12crac1 ~]$ srvctl start mgmtdb PRCR-1079 : Failed to start resource ora.mgmtdb CRS-5017: The resource action "ora.mgmtdb start" encountered the following error: ORA-01078: failure in processing system parameters LRM-00109: could not open parameter file '/u01/app/12.1.0/grid/dbs/init-MGMTDB.ora'. For details refer to "(:CLSN00107:)" in "/u01/app/12.1.0/grid/log/12crac2/agent/crsd/oraagent_grid/oraagent_grid.log".CRS-2674: Start of 'ora.mgmtdb' on '12crac2' failed CRS-5017: The resource action "ora.mgmtdb start" encountered the following error: ORA-01078: failure in processing system parameters ORA-01565: error in identifying file '+RACCRS/_mgmtdb/spfile-MGMTDB.ora'ORA-17503: ksfdopn:2 Failed to open file +RACCRS/_mgmtdb/spfile-MGMTDB.ora ORA-15056: additional error message ORA-17503: ksfdopn:2 Failed to open file +RACCRS/_mgmtdb/spfile-mgmtdb.ora ORA-15173: entry '_mgmtdb' does not exist in directory '/'ORA-06512: at line 4.

– 此问题造成原因是，我们dd了存放ocr的ASM磁盘组之后，里面的_MGMTDB相关文件也都将损坏丢失。从报错信息可见无法找到参数文件。
查看mgmtdb配置信息
[grid@12crac1 ~]$ srvctl config mgmtdb -all -verboseDatabase unique name: _mgmtdbDatabase name: Oracle home: /u01/app/12.1.0/gridOracle user: gridSpfile: +RACCRS/_mgmtdb/spfile-MGMTDB.oraPassword file: Domain: Start options: openStop options: immediateDatabase role: PRIMARYManagement policy: AUTOMATICDatabase instance: -MGMTDBType: ManagementDatabase is enabled
目前还不知如何修复mgmtdb的方法，因此我remove了下
[grid@12crac1 ~]$ srvctl remove mgmtdbRemove the database _mgmtdb?
