設(shè)備讀寫都正常，權(quán)限也都檢查過了沒有問題

200+0 records in
200+0 records out

求各位高手指點，謝謝！

這個lv損壞了～～謝謝。。

或者更改了ROOTDBS 的相關(guān)參數(shù)？？

回復(fù) 2# liaosnet


    沒有更改過什么參數(shù)阿，而且這個lv讀寫也都完全正常的阿。

dd if=/dev/datavg/lvrootdbs of=/dev/datavg/lvrootdbs count=200
這種測試雖然在理論上不會損壞已有數(shù)據(jù)，不過還是別寫到自己，of設(shè)為/dev/null比較放心吧

liaosnet

回復(fù) 3# leotangcw


    dd只是表明物理讀寫正常，說的損壞是數(shù)據(jù)庫上認為上面的數(shù)據(jù)頁損壞了。。。
