Re: ICH5 ATA DMA timeouts

2015-12-09 Thread Perry Hutchison
Interesting.  The ICH5 is part of the processor chipset, and it
could be "anywhere" on the system board, so finding/identifying
it (so as to point a fan at it, or figure out a way to add a
heatsink) may be less than straightforward -- but it's worth
keeping in mind as something to look into if problems arise.

Any idea where one finds cheap (but reliable) PCI SATA cards
these days?  It would have to be PCI -- this box does not have
PCI-E slots.

Re: ICH5 ATA DMA timeouts

2015-12-09 Thread Perry Hutchison
Er, there's nothing to check, yet.  I'm trying to *avoid* trouble
by finding out in advance about any dodgy hardware support.

In several of the cited threads, it was pretty clear that the
hardware was not faulty, since the identical hardware had run
properly on 4.x but started generating DMA timeouts on 5.x; also
diagnostics were run (=> drives OK), cables replaced, etc.  In at
least one case the failure was reproduced on a different box than
where it had originally been observed.

It was suspected that there might have been some kind of interaction
between geom and the ATA code, e.g. a timing problem, since many of
the failures involved software mirroring (vinum or gmirror).

 Good day everyone !
First of all I would advise you to change all of your hard drives interface 
cables with new ones.

Re: ICH5 ATA DMA timeouts

2015-12-06 Thread Florian Ermisch
I had some onboard (S)ATA controllers becoming unreliable in the
past. Two of them due to chipsets overheating under load which
were fixable with additional cooling. In the third one we just added
a cheap SATA card and spread the redundant disks between
onboard and add-on controller to make a temporary failure a minor
issue.

Re: ICH5 ATA DMA timeouts

Check cables and devices are in good condition. These things are usually 
a connectivity issue or device failing

Does anyone know the condition of the ICH5 ATA support in FreeBSD 10?

In preparing to repurpose an elderly Dell Dimension 4600 from Windows
to FreeBSD, and needing to decide what to do about drives, I found
several mentions in the archives* of ICH5 ATA DMA timeouts -- mostly
affecting the SATA ports, but the prevalence of SATA reports may
just indicate which ports were getting the most use:  a couple of
the reports involved the PATA ports.

While there have been commits to the ATA code since then, I didn't
find any definitive statement that the DMA timeouts had been fixed.
Did I miss something, or would I be better off using a separate SATA
or PATA PCI card instead of the ICH5's built-in ports?

ICH5 ATA DMA timeouts

2015-12-06 Thread Perry Hutchison
Does anyone know the condition of the ICH5 ATA support in FreeBSD 10?

In preparing to repurpose an elderly Dell Dimension 4600 from Windows
to FreeBSD, and needing to decide what to do about drives, I found
several mentions in the archives* of ICH5 ATA DMA timeouts -- mostly
affecting the SATA ports, but the prevalence of SATA reports may
just indicate which ports were getting the most use:  a couple of
the reports involved the PATA ports.

While there have been commits to the ATA code since then, I didn't
find any definitive statement that the DMA timeouts had been fixed.
Did I miss something, or would I be better off using a separate SATA
or PATA PCI card instead of the ICH5's built-in ports?

Relevant parts of dmesg (with no hard drives attached):
