Slow SATA write speeds with SMB

[Syntic]

Hi there,

I recently installed OpenBSD on one of my servers and I have noticed that I am experiencing slow SATA write speeds when using SMB to copy files across my network.

I currently have 1xSATA disk & 2xPATA disks in my server.
When I copy files across my network (GigE) to my PATA disk, I am seeing approx 600Mbps, however when I copy to the SATA disk I only see approx 125Mbps.
I also noticed that the CPU utilization (for SMBd) is at about 90% when copying to the SATA disk, but only hovers around 10% when copying the PATA disk.
I thought this may have been a driver issue with SATA, therefore causing the increased CPU when copying. But I copied some files across to the same SATA disk using FTP instead and the CPU stayed quite low and the write speeds were approx 600Mbps.

Does anybody have any ideas what may be causing the issues?

I have provided some info from dmesg below which may be of use.

sata disks normally (if not always) show up as sd's. You have 3 wd's.
That makes me confused and lead to believe you might be running a very
old OpenBSD version, something I cannot conclude from the partial dmesg
you included. Since you obviously have some issues you do not know how
to handle,

  ALWAYS INCLUDE THE ENTIRE DMESG

and do not make any assumptions of what would be necessary or not.

Cheers,
Alexander

Well you don't have dma on wd2.
Include the output of pcidump -v and I'll try cook up a diff.

I have yet to see anyone complaining about too much information. ;-)

Nevertheless, AFAICS (which is rather limited), it seems your wd2 disk
(which I assume is the problematic one) is attached as an IDE device but
is missing the corresponding wd0/wd1 line:

   wd1(pciide0:0:1): using PIO mode 4, Ultra-DMA mode 5

My guess would be that the mainboard is using some (possibly crappy)
IDE/SATA converter that, at least from OpenBSD's point of view, does not
support anything but the basics, causing the bad result.

Regarding FTP/SMB differences, I guess that could come from differences
in the protocols and how they do their disk access etc.

As noted, my knowledge is not great at these kind of things, so ACK's,
NAK's and/or corrections would still be appreciated. :-)

The AHCI implementation on your mb is not supported by the version of
OpenBSD
you are using.

That, or it is configured to something other than true AHCI by the bios. I'd
suggest checking to see if you have mode options for it in your bios and see
if that moves it from being a wd? drive (driven by pciide) to a sd? drive
(driven by the AHCI driver)

Just noticed this, thought I'd quickly give you the following tip :

Try forcing the pciide driver to use DMA by setting flags to 0x0001.
See pciide(4) for details (and the caveats listed there). Procede with
care to avoid dataloss (make backups etc), but this has helped me a
couple of times already.

To set this, boot -c and in UKC use 'change pciide' to alter the flags
value (keep all other things as they are). If this works for your
machine, you can use config(8) from your booted machine to configure
this permanently (remember to re-do this step after each upgrade).

Thanks for the suggestions.

I checked the BIOS configuration and it appears that the SATA controller was
set to IDE (not sure how that happened). I have now set it to AHCI, but I am
seeing another error in dmesg....

ahci0 at pci0 dev 14 function 0 "NVIDIA MCP73 AHCI" rev 0xa2: irq 11, AHCI
1.1
ahci0: failed to start command DMA on port 0, disabling
ahci0: failed to start command DMA on port 2, disabling
scsibus0 at ahci0: 32 targets, initiator 32

Does this mean that AHCI on my m/b is not supported in OpenBSD?
Any other thoughts?

I'm not an expert by any means when it comes to OpenBSD,
AHCI, or SATA, but here are some shots in the dark.

Does your machine have four SATA ports on it?  Can you
identify which of the four ports your two SATA drives are
plugged into?  Can you add additional SATA drives and see
if these errors are resolved or multiplied?

First guess is that the AHCI method for deciding which ports
have SATA devices attached is not working properly on your
motherboard/chipset.  Second guess is that the chipset or
motherboard has some problems with DMA happening the way
that the ahci device expects it to work.

Are there any sd devices listed after the scsibus0 line?

something like this?

scsibus1 at umass0: 2 targets, initiator 0
sd0 at scsibus1 targ 1 lun 0: <Y-E DATA, USB HS-CF Card,

The 2 SATA drives are currently connected to SATA port 1 & 2 (so the BIOS
tells me).
I just connected another SATA drive to port number 4 and the same occured
for that drive too.

There are no further details following the scsibus0 line.

I found some information about a bug with my Nvidia chipset and FreeBSD,
which refers to SATA drives -

Do you think there could be a relationship there (even though it's a
different plaform?

MCP77 is also unsupported.  but there was a patch floating about
on tech@ regarding ahci.  my notebook is quite unusable at the
moment so i can't test patches.  it has 44k interrupts a second
and everything takes forever.

some of the devs really need to give up their thinkpads and start
buying cheap msi or other stuff with amd and nvidia monstrosities :]

Yeah... you're like... the guy who is sits outside the estwing
factory hitting his balls with an estwing hammer - telling everyone
who comes in and out that it fucking hurts like hell and they shold
give up on those nails and things and start hitting their balls so
they can fix the hammer so it hurts less...

We'll get right on that..

Hope your balls get better soon.

Right, dealing with hardware that is unreliable on a daily basis is
exactly what I need.  I mean I am totally not busy at all so what is a
random reboot here and there anyway.

estwing? i think not. more like some low grade foundry in China..

Bob, always the funny guy.

if you can't let a joke go, you are the one hitting your balls.

all hw is unrealible to some degree, that's why we make backups.
i am sure there are lenovo models that pack some shitty components..
my thinkpad had it's own peculiarities (apm not working was one of them).

and once again, for the record.  that was a joke.  there is a smiley.
geez.  i know it's monday but loosen up a bit....

I don't use stinkpads either ;-)

You need to go write some acpi code and tell me again to loosen up.
Once you have taken a few bites of that shittaco tell me again how funny

Methinks some people like stuff that is LESS unreliable.
Even going so far as to make an OS that is LESS unreliable.

not that i disagree, but sometimes, it is enough to be unreliable once.

and reliable hw tends to make one sloppy and not think of
worst case scenarios :]
