InnoDB “corruption” ?
Posted by: Ingmar Sandberg

I am a newbie in using MySQL and I face a problem with InnoDB.

I use

5.1.63-0ubuntu0.11.10.1 Apache/2.2.20 (Ubuntu) MySQL client version: 5.1.63

and receive continosly the following error during reading data from a localy installed mySQL db.

InnoDB: Database page corruption on disk or a failed InnoDB: file read of page 387794.

After rebooting the system, I can gain access again to the db and I can read continuously the "corrupted" data w/o any problem at all (for few minutes or several hours) until the same problem re-appears (for different data read attempts)

Any idea on the source of the problem?

Thanks in advance,


Here is the error.log:

I have checked the HDD with S.M.A.R.T utility and I could not find any problem
I deactivate apprmor w/o any result
I also tried SQL_NO_CACHE option in the query w/o any result
