我把这2个数据文件drop掉，数据库会起来吗？
数据丢失是一定的了，不知道影响会多大，接触数据库时间很长，但是dba的活很少干。
多谢！


offline drop 后，如果数据库能启来还好，如果启不来的话这个drop掉的数据文件是否再不能用了？
多谢各位，最后确诊下，放假回来就动手了。
谢谢lemonlili ，小虫说是硬件有问题，我也觉得是，可是dbv检测又没问题，有些晕！
我的是dell服务器
ld0 --->  raid 5  100g
ld1 --->  volume 1  300g
ld2 --->  volume 1  300g
ld3 --->  volume 1  300g
系统启动时提示raid5 有错误 但是系统一直能用，
数据库装在ld1，数据文件在ld2 ld3.
准备在raid设置上再重新建一次，前提是数据库恢复了并做个备份（就是drop offline之后备份多少算多少了）
大家还有啥建议？谢谢 我菜


drop offline那2个数据文件(users012.dbf和users034.dbf)后，

数据能正常启动了，先做个备份，当然涉及到那2个drop掉的数据文件的表是不能访问了
