客户raid5发现有盘离线,并且其他盘有坏道,进行了多次换盘操作替换了大部分有坏道磁盘,但是部分文件访问依旧会报io错误
cp: error reading 'datafile': Input/output error |
数据库层面操作报
ORA-01115: IO error reading block from file %s (block # %s)ORA-27072: File I/O errorLinux-x86_64 Error: 5: Input/output errorAdditional information: 4Additional information: 21571487880 |
对于这样的情况,使用obet的forcecopy功能直接强制拷贝文件,可以最大限度求救数据obet forcecopy

运气不错,整体坏块非常少,而且没有涉及数据库字典文件,然后尝试恢复

虽然recover database成功,但是不幸open 库报ORA-600 kcbzib_kcrsds_1错误
