Re: Corrupt data - RAID sata_sil 3114 chip

Hello Bengt,

sil3114 is known to cause data corruption with some disks. So far I only know
about Seagate, but maybe there issues with newer Samsungs as well?

http://lkml.indiana.edu/hypermail/linux/kernel/0710.2/2035.html

Unfortuntely this issue has been simply ignored by the SATA developers :(
So if you want to be on the safe side, go an get another controller. 

I hope I won't frighten you too much, but it also might be possible one of 
your disks has a problem,  I have also seen a few broken disks, which don't 
return what you write to it...


Cheers,
Bernd

Hi,

I need some support for this soft-raid system.

I am running it as RAID5 with 4 samsung spinpoint 500G SATA300 tot 1.3T byte

And it runs in http://sm7jqb.dnsalias.com
I use mdadm sytem in a Debian Linux
CPU 1.2Mhz 1G memory ( my older 433Mhz / 512M dont work at all )

I have 'some courrupt' data. And I don't understand whay and how to fix it.
Mybee slow it down more, but how slow it down?

Any with experents from this cheep way of RAID systems.

Ask for more information and I can get it, logs, setup files and what 
you want
to know.

If this is an mdadm-related raid (not dmraid) please show all relevant md 
info, mdadm -D /dev/md0, I have cc'd linux-raid on this thread for you.

You'll want to read md.txt in /usr/src/linux/Documentation and read on 
the check and repair commands.

In addition, have you run memtest86 on your system first to make sure its 
not memory related?

Justin.
