Hi,
I already posted this on the linux-ide mailinglist but that
didn't end up with a solution and/or cause to this problem.
I'm
having a problem where a harddisk (not always the same) randomly shuts
down and is disconnected from the linux kernel. In other words I have to
reboot the system or physically unplug/replug the disk to get it to work
again. As stated this will happen to different disk at different times.
I will provide my configuration:
SuperMicro
SC-216
chassis (24 bay 2,5" disks)
24x Seagate ST9500420AS 500Gb
7200 RPM Hard Drives
3x SuperMicro AOC-SAT2-MV8 (SATA Controller
using the sata_mv kernel driver)
I use Debian Lenny 5.0
and
kernel: linux-image-2.6.30-bpo.2-amd64
(2.6.30-8~bpo50+1)
from the
backports repository.
The symptom is that after a
while of
operation a disk is shut down and kicked out of a RAID set.
It doesn't matter if there is load or not on the system.
The
logging
says:
sd 11:0:0:0: [sdk] Unhandled error code
sd 11:0:0:0:
Result: hostbyte=DID_BAD_TARGET
driverbyte=DRIVER_OK
sd 11:0:0:0:
end_request: I/O error, dev
sdk, sector 0
In this case sdk,
but it happens to all
disks.
Then the disk is not readable by the
system anymore.
When I check the disk for errors
(badblocks/smart) in another
system it doesn't give any errors.
I
only have this with
2,5" systems.
Is this a sata_mv
problem? A disk
problem? or anything else?
I can provide more info if
needed.

is it the same disks that fails
all the time?
---
As I said it doesn't happen to the same
disk.
Anyone knows where to look for a cause for this problem?
Kind
