6.检查磁盘头
[grid@darac1 ~]$ kfed read /dev/raw/raw1
kfbh.endian: 1 ; 0x000: 0x01
kfbh.hard: 130 ; 0x001: 0x82
kfbh.type: 1 ; 0x002: KFBTYP_DISKHEAD
kfbh.datfmt: 1 ; 0x003: 0x01
kfbh.block.blk: 0 ; 0x004: blk=0
kfbh.block.obj: 2147483648 ; 0x008: disk=0
kfbh.check: 300392945 ; 0x00c: 0x11e7a1f1
kfbh.fcn.base: 0 ; 0x010: 0x00000000
kfbh.fcn.wrap: 0 ; 0x014: 0x00000000
kfbh.spare1: 0 ; 0x018: 0x00000000
kfbh.spare2: 0 ; 0x01c: 0x00000000
B7F46200 00000000 00000000 00000000 00000000 [................]
Repeat 255 times
KFED-00322: Invalid content encountered during block traversal: [kfbtTraverseBlock][Invalid OSM block type][][0]
7.使用kfed恢复CRSDG的磁盘头，但因为备份信息也被损坏所以恢复时报错，而且没有手动备份
[grid@darac1 ~]$ kfed repair /dev/raw/raw1
KFED-00320: Invalid block num1 = [0], num2 = [1], error = [endian_kfbh]
没有通过自动备份的磁盘头信息来进行恢复，只能使用自动备份的ocr信息来恢复了操作如下。
8.创建磁盘组
[grid@darac1 ~]$ sqlplus / as sysasm
SQL*Plus: Release 11.2.0.4.0 Production on Thu Oct 13 13:00:42 2016
Copyright (c) 1982, 2013, Oracle. All rights reserved.
Connected to:
Oracle Database 11g Enterprise Edition Release 11.2.0.4.0 - Production
With the Real Application Clusters and Automatic Storage Management options
SQL> select * from v$asm_diskgroup;
no rows selected
SQL> create diskgroup CRSDG external redundancy disk '/dev/raw/raw1' attribute 'COMPATIBLE.ASM' = '11.2.0.0.0';
Diskgroup created.
9.查看自动备份的ocr文件
[root@darac1 bin]# ./ocrconfig -showbackup
PROT-26: Oracle Cluster Registry backup locations were retrieved from a local copy
darac2 2016/10/13 06:29:53 /u01/app/product/11.2.0/crs/cdata/darac-cluster/backup00.ocr
darac2 2016/10/13 02:29:45 /u01/app/product/11.2.0/crs/cdata/darac-cluster/backup01.ocr
darac2 2016/10/12 22:29:37 /u01/app/product/11.2.0/crs/cdata/darac-cluster/backup02.ocr
darac2 2016/10/12 02:27:20 /u01/app/product/11.2.0/crs/cdata/darac-cluster/day.ocr
darac2 2016/10/11 22:27:10 /u01/app/product/11.2.0/crs/cdata/darac-cluster/week.ocr
10.还原ocr
[root@darac1 bin]# ./ocrconfig -restore /u01/app/product/11.2.0/crs/cdata/darac-cluster/backup00.ocr
11.处理votedisk
[root@darac1 bin]# ./ocrconfig -restore /u01/app/product/11.2.0/crs/cdata/darac-cluster/backup00.ocr
[root@darac1 bin]# ./crsctl replace votedisk +CRSDG
Successful addition of voting disk 44eaf86504ea4f76bfb43cb7931a3fc7.
Successfully replaced voting disk group with +CRSDG.
CRS-4266: Voting file(s) successfully replaced
12.创建asm spfile
[grid@darac1 ~]$ vi /tmp/asm.txt
instance_type='asm'
large_pool_size=12M
remote_login_passwordfile= 'EXCLUSIVE'
asm_diskstring = '/dev/raw/raw*'
asm_power_limit =1
[grid@darac1 ~]$ sqlplus / as sysasm
SQL*Plus: Release 11.2.0.4.0 Production on Thu Oct 13 13:40:02 2016
Copyright (c) 1982, 2013, Oracle. All rights reserved.
Connected to:
Oracle Database 11g Enterprise Edition Release 11.2.0.4.0 - Production
With the Real Application Clusters and Automatic Storage Management options
SQL> create spfile='+CRSDG' FROM pfile='/tmp/asm.txt';
File created.
13.重启crs
[root@darac1 bin]# ./crsctl stop crs -f
