基于上述的Exception [type: IN_PAGE_ERROR, ] [] [PC:0x2C9C015, expgod()+43]错误,第一反应就是可能由于底层损坏导致数据块损坏,dbv检查文件是否报错
dbv-system

检查系统日志确认异常
20250208203059
尝试拷贝文件也报错
QQ20250208-203152
已经比较明确由于底层问题,解决给问题之前,需要先对文件系统进行处理,然后再对恢复出来的数据文件恢复数据

有客户由于磁盘坏道导致数据文件访问报ORA-27070 OSD-04016 O/S-Error等相关错误

检查系统日志,发现有报:设备 \Device\Harddisk0\DR0 有一个不正确的区块
disk-error

到目前为止基本上可以判断是文件系统或者磁盘层面出现坏道导致该问题（磁盘坏道概率更大）,使用工具对损坏数据文件进行强制拷贝,提示少量扇区数据无法拷贝
force-copy
通过dbv检查恢复出来文件效果
