Data corruption

From: paul
Date: Tue Aug 07 2007 - 17:47:07 EST

Since 2-3 month I have some random data corruption on my Linux server, after
checking disks independently (i'm using raid1on 2 sata disk, the problem is
the same w/o raid) and memory, hardware simce to be out of cause...

Here is my problem:
=> head --bytes=300m /dev/urandom > test
=> for i in `seq 0 9` ; do cp test test$i ; done
=> md5sum test*
I got :
014666c728c9e3b8299579fae499864a test
014666c728c9e3b8299579fae499864a test0
333fd93d093ac612cd8d5f65628f734e test1
1ab6ee68c6a7d9ff5a05f9d63f0f6df6 test2
96e96483e3175a59c9c05b6720514e1e test3
014666c728c9e3b8299579fae499864a test4
b24dbccc9f4831f8825ab4a55a3be4aa test5
8493efc9c14e4b5c162ac23696fbc16a test6
6a5f4301f66d0379049d79d0e14e2a87 test7
2c81cfa1c3a03aba134574922ee5d75c test8
2ea15c8392bfd0123472a80125bb3abe test9

^^^ that sounds really bad for my data :(

===================================================================
I did some tests :
* badblocks on the two disk with ro and rw tests => report no error
* memtest during 6 hours => report no error

* I reproduces the error
- under xen client host (first time issue)
- under xen hypervisor
- under basic kernel with raid mirroring + ext3 and raiserfs
- under basic kernel w/o raid but ext3 ans reiserfs

My configuration
* Asus P5B-VM
* 4 Gb [try with and w/o options memory remaping]
* Intel Core 2 Duo [normal speed and underclocked(233 bus speed)]
* Hd SATA WD 80Gb

System : opensuse 10.2
