asm磁盘加入vg恢复

又一个客户把asm disk做成pv,加到vg中,并且对lv进行了扩展(ext4的文件系统)
asm-disk-pv


这个客户做了上述操作之后,没有对lv进行写入其他数据,所以破坏较少(主要的破坏就是ext4的每个一段就会置空一部分block预留给文件系统写入元数据使用),通过winhex查看被破坏磁盘发现lvm信息
lvm

对于这种情况,通过对文件头进行修复,结合工具直接拷贝出来数据文件(个别文件元数据损坏通过基于block的方式恢复dbf)
asm-dbf

然后直接恢复dbf中数据文件(对于异常的主要是segment header被置空的tab使用dul单独扫描处理),实现客户数据的最大限度恢复

通过分析可能为:Bug 31104809 – ORA-600: [kcbr_apply_change_11] during adg recovery (Doc ID 31104809.8)
官方WORKAROUND:
In ADG, mount the database (do not open it) and restart media recovery; once
the affected redo log sequence is applied, open the ADG in read only mode.
