分区无法识别导致asm diskgroup无法mount

有客户咨询由于主机重启之后,导致四个磁盘组中的data2磁盘组无法mount(报ORA-15032,ORA-15017,ORA-15063),数据库无法open,让我们帮忙分析解决

这里很明显由于缺少asm disk导致data2无法正常mount,进一步分析发现data2是有两块磁盘组成

SUCCESS: diskgroup DATA2 was created

结合这部分信息,我们可以确定data2磁盘组是由两个磁盘组构成,分别为VOL010和VOL011,现在由于只发现了VOL011,因此data2磁盘组无法正常mount.观察发现该系统使用的是asmlib,通过oracleasm querydisk命令结合fdisk的盘符,
oracleasm-querydisk


基本上可以确定VOL010丢失应该在mpathb盘(由于只有该盘和分区未被使用,其他盘和分区已经全部被现在可以查询到的asmlib使用作为asmdisk)之上

Disk /dev/mapper/mpathb: 3846.7 GB, 3846677987328 bytes

Units = cylinders of 16065 * 512 = 8225280 bytes

255 heads, 63 sectors/track, 467665 cylinders

Sector size (logical/physical): 512 bytes / 512 bytes

                Device Boot      Start         End      Blocks   Id  System

/dev/mapper/mpathbp1p3          267350      467665  1609038270   83  Linux

这里我们发现奇怪现象:mpathb盘先使用parted分为一个mapthbp1分区,然后又使用fdisk分了三个p1p1,p1p2,p1p3三个子分区.然后我们查看/dev/mapper/中的设备情况
mpathb


发现没有p1p1,p1p2,p1p3这三个本该属于mapthb上的子分区.现在基本上明确,是由于对mapthb先使用了parted分区,然后再使用fdisk分区,在操作系统重启之后,无法正常识别相关子分区导致该问题.到此解决该问题的思路有三种.
1. 因为磁盘分区表信息是正常的,就是分区表信息没有同步到操作系统之上,想办法同步过去即可,os部分内容,此处忽略
2. 使用数据文件重组的方式直接对data2这两个asm disk进行重组,这里因为三个子分区未发现,直接对mapthbp1分区进行扫描即可,参考:asm disk header 彻底损坏恢复
3. 因为分区对于asm disk来说主要就是设置了磁盘的偏移量和大小,如果找到磁盘的偏移量,然后确定asm disk大小,直接通过dd命令把该部分dd到新的磁盘设备之上,然后直接mount磁盘组即可,这里重点讲解第三种方法恢复处理
使用dd出来mapthp1的磁盘头,然后使用bbed找出来偏移量,主要依据是第一次出现01820101信息的部分

        LOGFILE         log.bbd
        SPOOL           No

这里基本上可以定位到asm disk header对于mapthbp1的偏移量为32256,dd出来asm disk header分析
dd


使用kfed查看磁盘头信息
kfed
kfed2


现在基本上可以确定,asm disk大小为1572871M,磁盘的偏移量为32256,然后使用dd命令把这部分dd到新的磁盘设备上,然后oracleasm scandisks后
asm-mount
asmcd-lsdg
oracle-open


data2 mount成功,数据库正常open,此数据库完美恢复

file 1 block 128 corrupted system回滚段坏块修复

有个数据库file 1 block 128 坏块导致数据库无法启动报错如下
file-1-block-128


该数据库版本是11.2.0.1,根据我们的经验该block是system rollback 的segment header,以下为我在正常哭查询结果

SQL> select file_id,block_id,blocks from dba_extents where segment_name='SYSTEM';

   FILE_ID   BLOCK_ID     BLOCKS
---------- ---------- ----------
         1        128          8
         1        136          8
         1        528          8
         1        536          8
         1        544          8
         1        552          8

6 rows selected.

dump file 1 block 128 结果

Dump all the blocks in range:
buffer tsn: 0 rdba: 0x00400080 (1/128)
scn: 0x0000.00000000 seq: 0xff flg: 0x04 tail: 0x00000eff
frmt: 0x02 chkval: 0x1387 type: 0x0e=KTU UNDO HEADER W/UNLIMITED EXTENTS
Hex dump of block: st=0, typ_found=1

这里可以看到block scn为0x0000.00000000,而且数据块已经被标记为坏块
dbv检查坏块结果
dbv


从这里可以看出来主要错误是由于Controlscn: 0x0004.119fe191 greater than blockscn: 0x0000.00000000,拷贝system文件到本地,使用bbed修改

bbed修复坏块

ALTER DATABASE RECOVER datafile 1 报错
尝试recover datafile 1之后报ORA-600 kcbrapply_4,ORA-600 kcfrbd_3,ORA-600 kcbrapply_12等错误,从报错信息看,出现这些错误的原因,是由于断电导致坏块引起.

这次运气不错,system坏的是mon_mods$,undo异常可以重建,基本上可以说没有数据丢失,数据库恢复完成.
重要的库,通过open过程报错信息,分析可能的坏块所属对象,然后确定处理方法,以免造成永久性数据块损坏.

csc(0x0000.1f8adab3) higher than block scn(0x0000.00000000)

数据库虽然正常open了,但是由于system有坏块,导致数据库导出有部分表报错,客户希望通过修复坏块完美解决该问题

通过观察这段日志,基本上可以发现主要是FILE 45,虽然提示坏块但是最终验证确定为正常块(类似:Reread (file 45, block 7836) found valid data),这里主要是file 5,报了大量的ORA-600[3020].
