I'm currently running

Linux *** 2.6.23 #1 SMP PREEMPT Sat Jan 26 17:59:58 CET 2008 x86_64
Intel(R) Pentium(R) D CPU 3.20GHz GenuineIntel GNU/Linux
with the libata-tj-2.6.23-20071011 path for 2.6.23

and for testing purposes

linux-2.6.24-rc6-mm1


on a Asus P5WDG2-WS with two PCI-X Dawicontrol DC 4300 Controllers and two
Dawicontrol DC 6510 PM port multipliers to get 16 sata ports. (the linux
partition is on a ide drive)

the second raid array with 8 Samsung HD-LJ 501 works great without any
errors. but the first raid with 8 Maxtor 6V300F0 produces one error after
another after mounting the filesystem:

Filesystem "dm-0": Disabling barriers, not supported by the underlying device
XFS mounting filesystem dm-0
Ending clean XFS mount for filesystem: dm-0
Filesystem "dm-1": Disabling barriers, not supported by the underlying device
XFS mounting filesystem dm-1

I could solve the problem by ncq blacklisting the "Maxtor 6V300F0" devices
in libata-core.c

That's a strange story.  The reported error was PHY readiness changed
and Device exchanged, both of which point to hotplug event.  Maybe
something causes the firmware to reset?  What happen if you only leave
two drives on the port multiplier and remove the NCQ blacklist?  Also,
does the error ever occur on the drives which are connected directly to
the controller?

No the error only occures on the drives on the pm. I can test the pm with
two Maxtor drives tomorrow (currently backing up the raid).

With one, two and three drives on the pm I got no errors, so I tried to
change the power supply. I got two power supplies for the 16 harddrives
and the second one (with all Maxtor drives and the first pm) was failing.
After changing the power supply all problems where gone. Sorry for the
confusion.

The only remaining issue is that some sata links are only working with 1.5
gbps and I can't figure out why. (ata3,4,5,6.x are the Maxtor drives and
ata7,8,9,10.x are the Samsung ones)

It's amazing that, in SATA, PSU-problem-verified / PSU-problem-suggested
ratio is significant.  I don't think this ever was the case with PATA.
SATA link seems much more susceptible to power quality and allows
hooking up whole lot of drives.

Hmm... That's how the hardware negotiated transfer rate w/ each other.
SControl is telling the hardware that there's no speed limit and to go
as high as it can but somehow 3.0Gbps negotiation failed and the link
speed is limited to 1.5Gbps for some of the ports.  Is the result always
the same?  What happens if you swap drives between ports?  Also, if you
have an extra PSU lying around, can you hook it up with some of the
drives such that the load is more distributed.

Oh.. Another note on PSU.  I don't know whether this still holds for
more recent ones but mid-to-high range multi-lane PSUs sometimes have
lesser juice on 12v rail available for disks than low cost single lane
PSUs.  This is because high power 12v lanes are allocated to power video
cards and disks can only pull power from (usually) single weak 12v lane.

Thanks.

Shuffling the drives did not change anything to the linkspeed of the 3
ports running with 1.5 Gbps. Looks like the problem is port-related.
The first PSU (Multilane) offers (measured) 12,20 V on both lanes. This
falls during read/write access on all drives attached down to 12,10 V.
The second PSU (Singlelane) offers (measured) 11,75 V. This doesn't change
during read/write access on all drives attached. I tested the second PSU
without anything attached and it still offered 11,75 V.

I will try to add another PSU this evening and remeasure.
Currently the whole machine needs about 350W.
The PSUs are Targan 500W (Multilane - 2x12V 10A) and Noname 350W
(Singlelane - 1x12V 10A) so this 'should' be enough...

This night i copied the backup back to the first raid (the Maxtor drives)
without any error but during the transfer i got this on the second
(mounted but unused) raid:

Hmm... Okay.  Maybe the signal traces or connectors have some problems.
 But 3.0Gbps on downstream port doesn't make any difference anyway so
unless it leads to errors, it should be fine.

That explains the PHY dropouts.  I've even seen drives to do hard reset
accompanying emergency head unload due to voltage dropping when high IO
load hits.  Of course, data in cache is lost.

11.75 is still in spec and it doesn't fluctuate.  I like this power much
better.

Maybe one of the lane is only connected to video power connectors?
IIRC, that was the idea of multilane power anyway.

Timeout during heavy IO can be caused from a number of things and bad
power is one of them.

Please lemme know your test result.

Sorry for my late answer, but i had to sort this out first.
After replacing the first PSU with a new Corsair 650W the power no longer
fluctuated more than 0,01 V (and this only when booting up the drives...)
I did a full resync on both raid arrays and got no more errors or resets,
but there were some inconsitencies during sync and the xfs filesystem on
both arrays had to be repaired. Are these problems caused by the pm resets
?

Thanks for your patience.

libata EH won't lose any data as long as the hardware doesn't.  If power
fluctuates causing your drive to briefly power down - this does happen
and you can hear the drive doing emergency unload when it happens, the
data in write buffer can be lost.  On coming back, all that libata can
know is that the PHY suffered brief connection loss, so it resets the
device and goes on, so the data in the cache is lost now.  It's
basically pulling the power plug from the harddrive while write is going
on and connecting it back quickly.  You're bound to lose data.

After I got the new PSU and the raid was in full sync without any error
for 48h, I thought all problems were gone. Today the sata errors
reappeared and whenever the load is high enough I get the following:

Those are time outs for FLUSH.  libata told the drive to flush its cache
onto the media and the drive failed to finish that in 30secs.  As FLUSH
itself is a non-data command, this problem usually isn't caused by
transport layer problems.  This is a pretty good clue that the drive is
knee-deep in s**t.  What does 'smartctl -a' tell you about the drive?

What exact brand/model drives are those again (hdparm --Istdout, please) ?

If I have a similar unit here, I may try to reproduce this.

Dusty, can you please provide the info for Mark?  Let's see if Mark can
reproduce this.

Thanks.

Re: libata pm

Hi everybody,

it looks like this will be a never ending story...

>>> After I got the new PSU and the raid was in full sync without any
>>> error for 48h, I thought all problems were gone. Today the sata errors
>>>  reappeared and whenever the load is high enough I get the following:
>>>
I exchanged two (probably failing) of the eight harddrives with new ones.
All remaining disks have a good smart state and are fully readable when
the raid is not active. As long as I mount the filesystem on the raid
readonly there wont happen any error, but the moment I mount it rw and try
to copy something to the fs on the raid I get the already known timeout.
At least I get a little bit desperate now...
