Random shutdown of disks using sata_mv

Random shutdown of disks using sata_mv

[Caspar Smit]

Hi,

I'm having a problem where in random one of my disks 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.

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.

Kind regards,
Caspar Smit

We are investigating a similar type of problem seen on several of our systems.
Seemingly at random (though some systems seem more susceptible than others) we see the ata link reset and subsequently there is a FAILED TO IDENTIFY error logged.  smartctl is unable to get information from the drive and a power cycle of the drive is required to bring it back on line.

I would be interested to know if the ata level errors are similar to those we are seeing.

Posting kernel messages would be helpful.  Just in case, there was a
similar report where the new devicekit based smart polling caused HSM
violation errors and device shutdown on certain SSDs with flaky
firmwares.

Thanks.

This part of the log doesn't show any message from the libata nor the
sata_mv drivers.
can you send the whole system log?

Hi Simon,

We are not experiencing that "FAILED TO
IDENTIFY" error.

Kind regards,
Caspar

means that a timeout error occurred, the after then, the disk didn't respond.
is it the same disks that fails all the time?

As the subject says:
it is
random, so not everytime the same disk. This makes it extra hard to
troubleshoot.
