客户反馈,数据库无法正常启动，通过分析asm的alert日志发现,data磁盘组mount成功之后,没有一会儿自动dismount掉

这里看主要是由于asm 磁盘组需要做COD recovery导致无法正常稳定的mount,主要原因是遭遇到asm disk的逻辑坏块(存储物理上看是ok的,但是实际数据在asm中看是异常的)

数据库alert日志报错

对于这类故障处理相对比较容易,通过patch asm，让data磁盘组稳定mount,然后open库,迁移数据,实现数据0丢失,完美恢复

KFED-00322: Invalid content encountered during block traversal: [kfbtTraverseBlock][Invalid OSM block type][][0]

通过kfed分析,该block确实异常,该block主要记录au的分配信息,如果asm 磁盘组的空间不变化,不执行rebalance,一般不会主动访问该block,不访问该block磁盘组也就不会dismount,按照这个解决思路,通过patch解决,让oradata磁盘组不再执行rebalance和分配/回收空间即可一直稳定的mount

数据库直接open成功,实现数据0丢失

一次完美的asm disk被格式化ntfs恢复

发表于 2019 年 7 月 13 日由惜分飞

机器上查看磁盘信息

这个客户比较幸运,asm disk被格式化之后,没有进行任何写操作,理解对现场进行了保护,没有任何的二次破坏.因为处理过多起类似故障(oracle asm disk格式化恢复—格式化为ntfs文件系统,oracle asm disk格式化恢复—格式化为ext4文件系统又一例asm格式化文件系统恢复),有一定的经验,一般三种方案恢复数据文件：
1)运气好直接通过kfed进行修复asm disk,然后mount起来,然后把数据文件拷贝到文件系统中
2)通过相关工具把asm disk中相关的数据文件拷贝到文件系统中
3)如果损坏的严重,通过底层碎片,把相关数据文件恢复到文件系统中
拷贝完成数据文件之后,然后根据文件的情况有几种可能性:
1)直接open数据库,处理可能的其他坏块
2)通过一些方法强制拉库,然后对其进行导出导入新库
3)通过工具直接恢复表数据,甚至恢复部分核心数据
这次的恢复运气不错,对asm disk进行一系列修复之后,asm 磁盘组mount成功

运气不错,除+DATA/orcl/datafile/XFF63.dmp文件上面有坏块之外其他文件没有发现坏块,对该文件进行特殊方式拷贝处理
dbv检查该文件

C:\Users\Administrator>dbv file=i:/rmanback/26.dbf

这次运气非常好,该文件也只有一个坏块,整体来说,把正在运行的asm disk磁盘格式化为ntfs格式化,整个数据库文件只发现一个坏块.拷贝数据文件,redo,ctl等之后

通过重建控制文件尝试open数据库

SQL> @ctl.sql

控制文件已创建。
SQL> RECOVER DATABASE;
完成介质恢复。
SQL> ALTER DATABASE OPEN;

数据库已更改。

通过dba_extents 定位坏块对象,然后根据实际情况处理(index直接rebuild,表跳过,lob置空等方法),确定数据没有问题,重建磁盘组,数据回迁,恢复完美完成
