Oracle 11gR2 RAC GRID模拟OCR和Votedisk损坏及恢复过程
1、破坏前的ocr和votedisk信息检查
检查ocr自动备份[root@rac1 ~]# ocrconfig -showbackuprac2 2013/10/13 09:45:30 /u01/grid/product/11.2.0/cdata/rac-cluster/backup00.ocrrac2 2013/10/13 05:45:29 /u01/grid/product/11.2.0/cdata/rac-cluster/backup01.ocrrac2 2013/10/13 01:45:28 /u01/grid/product/11.2.0/cdata/rac-cluster/backup02.ocrrac2 2013/10/12 01:45:26 /u01/grid/product/11.2.0/cdata/rac-cluster/day.ocrrac2 2013/09/28 02:55:56 /u01/grid/product/11.2.0/cdata/rac-cluster/week.ocrPROT-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 ~]# ocrcheckStatus of Oracle Cluster Registry is as follows :Version : 3Total space (kbytes) : 262120Used space (kbytes) : 2720Available space (kbytes) : 259400ID : 2026562699Device/File Name : +OCRDATADevice/File integrity check succeededDevice/File not configuredDevice/File not configuredDevice/File not configuredDevice/File not configuredCluster registry integrity check succeededLogical 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 OCR1Disk "OCR1" is a valid ASM disk on device /dev/sda1[8,1][root@rac1 ~]# /etc/init.d/oracleasm querydisk -d OCR2Disk "OCR2" is a valid ASM disk on device /dev/sdh1[8,113][root@rac1 ~]# /etc/init.d/oracleasm querydisk -d OCR3Disk "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spfileSQL> show parameter spfile;NAME TYPE VALUE------------------------------------ ----------- ------------------------------spfile string +OCRDATA/rac-cluster/asmparameterfile/registry.253.825083547
SQL> create pfile='/tmp/asmbak.ora' from spfile; --备份到/tmp/asmbak.oraFile 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=1010+0 records in10+0 records out10485760 bytes (10 MB) copied, 0.005454 seconds, 1.9 GB/s[root@rac1 ~]# dd if=/dev/zero of=/dev/sdh1 bs=1M count=1010+0 records in10+0 records out10485760 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 -tName Type Target State Host------------------------------------------------------------ora.DATA.dg ora....up.type ONLINE ONLINE rac1ora.FRA.dg ora....up.type ONLINE ONLINE rac1ora....ER.lsnr ora....er.type ONLINE ONLINE rac1ora....N1.lsnr ora....er.type ONLINE ONLINE rac1ora.OCRDATA.dg ora....up.type ONLINE ONLINE rac1ora.asm ora.asm.type ONLINE ONLINE rac1ora.eons ora.eons.type ONLINE ONLINE rac1ora.gsd ora.gsd.type OFFLINE OFFLINEora....network ora....rk.type ONLINE ONLINE rac1ora.oc4j ora.oc4j.type OFFLINE OFFLINEora.ons ora.ons.type ONLINE ONLINE rac1ora....SM1.asm application ONLINE ONLINE rac1ora....C1.lsnr application ONLINE ONLINE rac1ora.rac1.gsd application OFFLINE OFFLINEora.rac1.ons application ONLINE ONLINE rac1ora.rac1.vip ora....t1.type ONLINE ONLINE rac1ora....SM2.asm application ONLINE ONLINE rac2ora....C2.lsnr application ONLINE ONLINE rac2ora.rac2.gsd application OFFLINE OFFLINEora.rac2.ons application ONLINE ONLINE rac2ora.rac2.vip ora....t1.type ONLINE ONLINE rac2ora.ractest.db ora....se.type ONLINE ONLINE rac1ora....ry.acfs ora....fs.type ONLINE ONLINE rac1ora.scan1.vip ora....ip.type ONLINE ONLINE rac1

3、 故障定位
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)[root@rac1 ~]# tail -f /u01/grid/product/11.2.0/log/rac1/alertrac1.log........[ohasd(28327)]CRS-2765:Resource 'ora.cssdmonitor' has failed on server 'rac1'.2013-10-13 11:22:46.094[cssd(28791)]CRS-1713:CSSD daemon is started in clustered mode2013-10-13 11:22:46.178[cssd(28791)]CRS-1637:Unable to locate configured voting file with ID 5c190e6a-b4c04fac-bfdd4ca0-e836a798; details at (:CSSNM00020:) in /u01/grid/product/11.2.0/log/rac1/cssd/ocssd.log2013-10-13 11:22:46.179[cssd(28791)]CRS-1637:Unable to locate configured voting file with ID abcc18af-e6214fbc-bfa02fad-1c41b21b; details at (:CSSNM00020:) in /u01/grid/product/11.2.0/log/rac1/cssd/ocssd.log2013-10-13 11:22:46.179[cssd(28791)]CRS-1705:Found 1 configured voting files but 2 voting files are required, terminating to ensure data integrity; details at (:CSSNM00021:) in /u01/grid/product/11.2.0/log/rac1/cssd/ocssd.log2013-10-13 11:22:46.179[cssd(28791)]CRS-1603:CSSD on node rac1 shutdown by user.2013-10-13 11:22:52.768[ohasd(28327)]CRS-2765:Resource 'ora.diskmon' has failed on server 'rac1'.

发现服务都无法启动,根据上面的提示检查ocssd.log日志文件2013-10-13 11:43:47.201: [ SKGFD][1084574016]Lib :ASM:/opt/oracle/extapi/64/asm/orcl/1/libasm.so: closing handle 0x1dc67d90 for disk :ORCL:OCR3:2013-10-13 11:43:47.201: [ CSSD][1084574016]clssnmvDiskVerify: file is not a voting file, cannot recognize on-disk signature for a voting2013-10-13 11:43:47.201: [ CSSD][1084574016]clssnmvDiskVerify: file is not a voting file, cannot recognize on-disk signature for a voting2013-10-13 11:43:47.201: [ CSSD][1084574016]clssnmvDiskVerify: file is not a voting file, cannot recognize on-disk signature for a voting2013-10-13 11:43:47.201: [ CSSD][1084574016]clssnmvDiskVerify: file is not a voting file, cannot recognize on-disk signature for a voting2013-10-13 11:43:47.201: [ CSSD][1084574016]clssnmvDiskVerify: file is not a voting file, cannot recognize on-disk signature for a voting2013-10-13 11:43:47.201: [ CSSD][1084574016]clssnmvDiskVerify: file is not a voting file, cannot recognize on-disk signature for a voting2013-10-13 11:43:47.201: [ CSSD][1084574016]clssnmvDiskVerify: file is not a voting file, cannot recognize on-disk signature for a voting

上面错误写的非常清楚无法识别表决磁盘,继续查看下面的log,2013-10-13 11:43:47.201: [ SKGFD][1084574016]Handle 0x1dc61820 from lib :ASM:/opt/oracle/extapi/64/asm/orcl/1/libasm.so: for disk :ORCL:OCR3:2013-10-13 11:43:47.201: [ CLSF][1084574016]Opened hdl:0x1dc17dc0 for dev:ORCL:OCR3:2013-10-13 11:43:47.213: [ CSSD][1084574016]clssnmvDiskVerify: Successful discovery for disk ORCL:OCR3, UID 31e0a9df-91514f73-bf50a4e0-a344af3d, Pending CIN 0:1378101162:0, Committed CIN 0:1378101162:02013-10-13 11:43:47.213: [ CLSF][1084574016]Closing handle:0x1dc17dc02013-10-13 11:43:47.213: [ SKGFD][1084574016]Lib :ASM:/opt/oracle/extapi/64/asm/orcl/1/libasm.so: closing handle 0x1dc61820 for disk :ORCL:OCR3:2013-10-13 11:43:47.213: [ CSSD][1084574016]clssnmvDiskVerify: Successful discovery of 1 disks

上面log写的很清楚,在3快磁盘中只有1块可用,voting file 0,voting file 1 notfound,根据上面的log找到OCR3是可以用的,通过oracleasmdisk命令可以找到我们损坏的磁盘除了OCR3剩下的两块就是OCR1 和OCR2了
[root@rac1 ~]# /etc/init.d/oracleasm listdisksDATA1DATA2DATA3FRA1FRA2OCR1OCR2OCR3

4、实施ocr与votedisk恢复
先重启一下操作系统[root@rac1 ~]# reboot
重启完成后发现ASM磁盘OCR1和OCR2已经找不到了[root@rac1 ~]# /etc/init.d/oracleasm listdisksDATA1DATA2DATA3FRA1FRA2OCR3

由于之前我只破坏10m的内容,这里我将这两个磁盘格式化后重新分区(一定要注意是哪两块磁盘,错了就麻烦了)[root@rac1 ~]# mkfs -t ext3 /dev/sda1mke2fs 1.39 (29-May-2006)Filesystem label=OS type: LinuxBlock size=4096 (log=2)Fragment size=4096 (log=2)1024128 inodes, 2047996 blocks102399 blocks (5.00%) reserved for the super userFirst data block=0Maximum filesystem blocks=209715200063 block groups32768 blocks per group, 32768 fragments per group16256 inodes per groupSuperblock backups stored on blocks:32768, 98304, 163840, 229376, 294912, 819200, 884736, 1605632Writing inode tables: doneCreating journal (32768 blocks): doneWriting superblocks and filesystem accounting information: doneThis filesystem will be automatically checked every 32 mounts or180 days, whichever comes first.
