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 :

^^^ 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
Corruption with which controller? pata_jmicron? ata_piix? ahci?
Can you reproduce with 2.6.23-rc2? If not, please report the bug to
OpenSuSE, since we only support unmodified vanilla kernels here.
