恢复损坏的表决磁盘（votedisk）和OCR
如何恢复损坏的表决磁盘（votedisk）和OCR
冗余:
Voting 磁盘(不要使用偶数个)：
External 需要最少1个 Voting 磁盘（或者1个 failure group）
Normal 需要最少3个 Voting 磁盘（或者3个 failure group）
High 需要最少5个 Voting 磁盘（或者5个 failure group）
缺少 failure group 会引起 voting disk 创建失败。例如 ORA-15274: Not enough failgroups (3) to create voting files
OCR:
10.2 和 11.1，最多2个 OCR 设备：OCR 和 OCRMIRROR
11.2+，最多5个 OCR。
步骤：
一、orc运行信息
1.查OCR有哪些备份：
[root@node1 ~]# /u01/app/11.2.0/grid/bin/ocrconfig -showbackup
node1 2014/12/10 13:08:14 /u01/app/11.2.0/grid/cdata/lxxhscan/backup00.ocr
node1 2014/12/10 09:08:13 /u01/app/11.2.0/grid/cdata/lxxhscan/backup01.ocr
node1 2014/12/10 05:08:13 /u01/app/11.2.0/grid/cdata/lxxhscan/backup02.ocr
node1 2014/12/09 09:08:07 /u01/app/11.2.0/grid/cdata/lxxhscan/day.ocr
node2 2014/12/02 07:20:17 /u01/app/11.2.0/grid/cdata/lxxhscan/week.ocr
PROT-25: Manual backups for the Oracle Cluster Registry are not available
[root@node1 ~]#
2.查看表决盘信息：
[root@node1 ~]# /u01/app/11.2.0/grid/bin/crsctl query css votedisk
## STATE File Universal Id File Name Disk group

[root@node1 ~]#
3.检查信息ocr
[root@node1 ~]# /u01/app/11.2.0/grid/bin/ocrcheck
Status of Oracle Cluster Registry is as follows :

2. vi /etc/multipath.conf
添加如下

# path_checker readsector0

path_grouping_policy multibus
# path_checker readsector0
path_selector "round-robin 0"
failback manual
rr_weight priorities
no_path_retry 5
rr_min_io 10
}
3.重启服务 service multipathd restart
4验证
ls -l /dev/mapper/
. multipath -ll
[root@node11 etc]# service multipathd restart --重启会导致磁盘权限掉失（如果以前用chmod chown付权限的就好掉失，如果以前用udev 付权限的就不会。）

5.分区 fdisk成分区(分不分区自己定) ：使用partprobe可以不用重启系统即可配合fdisk工具创建新的分区
fdisk /dev/mapper/ocrnew1
fdisk /dev/mapper/ocrnew2
fdisk /dev/mapper/ocrnew3
5.添加权限(权限重新付)
chown grid:asmadmin /dev/mapper/ocrnew1*
chown grid:asmadmin /dev/mapper/ocrnew2*
chown grid:asmadmin /dev/mapper/ocrnew3*
chmod 660 /dev/mapper/ocrnew1*
chmod 660 /dev/mapper/ocrnew2*
chmod 660 /dev/mapper/ocrnew3*
chown grid:asmadmin /dev/mapper/archlog*
chown grid:asmadmin /dev/mapper/fra*
chown grid:asmadmin /dev/mapper/ocr1*
chown grid:asmadmin /dev/mapper/ocr2*
chown grid:asmadmin /dev/mapper/ocr3*
chown grid:asmadmin /dev/mapper/racdata*
chmod 660 /dev/mapper/archlog*
chmod 660 /dev/mapper/fra*
chmod 660 /dev/mapper/ocr1*
chmod 660 /dev/mapper/ocr2*
chmod 660 /dev/mapper/ocr3*
chmod 660 /dev/mapper/racdata*
三、开始恢复
确定ocr,votedisk,asm spfile存在一个独立asm diskgroup中

在我们破坏了ocr所在的asm disk的磁盘后,启动crs明显提示无法找到votedisk信息
###################正式开始恢复###################
以-excl -nocrs 方式启动集群，这将启动ASM实例 但不启动CRS
1.强制关闭crs
[root@node1 ~]# /u01/app/11.2.0/grid/bin/crsctl stop crs -f

2.exclusive模式启动crs 以-excl -nocrs 方式启动集群，这将启动ASM实例 但不启动CRS 启动到独占模式且不启动ora.crsd:
crsctl start crs -excl -nocrs
[root@node1 ~]# /u01/app/11.2.0/grid/bin/crsctl start crs -excl -nocrs
CRS-4123: Oracle High Availability Services has been started.

3.组重建原ocr和votedisk所在磁盘组：
注意：这里是在grid用户下
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)
为了操作方便,建议创建磁盘组和以前ocr所在异常的磁盘组一致
SQL> create diskgroup OCR_VOTE normal redundancy disk '/dev/mapper/ocrnew1p1','/dev/mapper/ocrnew2p1','/dev/mapper/ocrnew3p1' attribute 'compatible.asm'='11.2.0.4.0', 'compatible.rdbms'='11.2.0.4.0';
Diskgroup created.
4.还原ocr
[root@node1 ~]# cd /u01/app/11.2.0/grid/cdata/lxxhscan/
[root@node1 lxxhscan]# ll

[root@node1 lxxhscan]# /u01/app/11.2.0/grid/bin/ocrconfig -restore backup_20141211_111501.ocr
恢复表决盘的准备工作：
show parameter asm_diskstring
SQL> show parameter asm_diskstring;

------------------------------------ ----------------------
VALUE
------------------------------

如果asm_diskstring没有值，表示ASM磁盘用的是默认ASM磁盘搜索路径。
修改成实际的ASM磁盘搜索路径：（不然要报错）
[root@node1 lxxhscan]# /u01/app/11.2.0/grid/bin/crsctl replace votedisk +OCR_VOTE

6.处理votedisk 检查
/u01/app/11.2.0/grid/bin/crsctl replace votedisk +OCR_VOTE

8重启集群服务，检查是否已经恢复正常：

10.到此为止表决盘的恢复正常完成了。
前记:
OCR：管理集群节点的相关信息及实例到节点的映射信息。 votedisk：解决分区集群中的集群成员资格问题。
ASM磁盘组冗余的三种类型：external、normal、high,这里恢复的是normal状态,模拟OCR磁盘或votedisk不可用时，
一般OCR磁盘还有ASMPARAMETERFILE的ASM参数文件，操作前需要先备份 create pfile='/home/oracle/11' from spfile冗余:
Voting 磁盘(不要使用偶数个)：
External 需要最少1个 Voting 磁盘（或者1个 failure group）
Normal 需要最少3个 Voting 磁盘（或者3个 failure group）
High 需要最少5个 Voting 磁盘（或者5个 failure group）
缺少 failure group 会引起 voting disk 创建失败。例如 ORA-15274: Not enough failgroups (3) to create voting files
OCR:
10.2 和 11.1，最多2个 OCR 设备：OCR 和 OCRMIRROR
11.2+，最多5个 OCR。
步骤：
一、orc运行信息
1.查OCR有哪些备份：
[root@node1 ~]# /u01/app/11.2.0/grid/bin/ocrconfig -showbackup

3.组重建原ocr和votedisk所在磁盘组：
注意：这里是在grid用户下
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)
为了操作方便,建议创建磁盘组和以前ocr所在异常的磁盘组一致
SQL> create diskgroup OCR_VOTE normal redundancy disk '/dev/mapper/ocrnew1p1','/dev/mapper/ocrnew2p1','/dev/mapper/ocrnew3p1' attribute 'compatible.asm'='11.2.0.4.0', 'compatible.rdbms'='11.2.0.4.0';
Diskgroup created.
4.还原ocr
[root@node1 ~]# cd /u01/app/11.2.0/grid/cdata/lxxhscan/
[root@node1 lxxhscan]# ll
total 58112
-rw------- 1 root root 7438336 Dec 11 09:08 backup00.ocr

[root@node1 lxxhscan]#
/u01/app/11.2.0/grid/bin/ocrconfig -restore backup_20141211_111501.ocr
[root@node1 lxxhscan]# /u01/app/11.2.0/grid/bin/ocrconfig -restore backup_20141211_111501.ocr
恢复表决盘的准备工作：
show parameter asm_diskstring
SQL> show parameter asm_diskstring;
NAME TYPE
------------------------------------ ----------------------
VALUE
------------------------------
asm_diskstring string
如果asm_diskstring没有值，表示ASM磁盘用的是默认ASM磁盘搜索路径。
修改成实际的ASM磁盘搜索路径：（不然要报错）
[root@node1 lxxhscan]# /u01/app/11.2.0/grid/bin/crsctl replace votedisk +OCR_VOTE

6.处理votedisk 检查
/u01/app/11.2.0/grid/bin/crsctl replace votedisk +OCR_VOTE
[root@node11 lxxhscan]# /u01/app/11.2.0/grid/bin/crsctl replace votedisk +OCR_VOTE

7.创建asm spfile（原来是有的，重新创建没有。重新创建时备份spfile）----------------------
SQL> show parameter spfile; ---原来

------------------------------------ ----------------------
VALUE
------------------------------
spfile string
+OCR_DATA/racscan/asmparameter

SQL> show parameter spfile;--没有
NAME TYPE
------------------------------------ ----------------------
VALUE
------------------------------
spfile string
SQL>
create spfile='+OCR_VOTE' FROM pfile='/home/grid/11';
8重启集群服务，检查是否已经恢复正常：
[root@node1 lxxhscan]# /u01/app/11.2.0/grid/bin/crsctl stop crs

9.这里crs已经恢复正常，进一步检查ocr,votedisk,asm spfile情况
