NASLite Network Attached Storage

Would you mind taking a look at this syslog? The APIC section seems weird, so is the end where there's a warning for the hda.

A few days ago the RAID array got corrupted, without a reason. Drives are OK, 3Ware 8006-2LP is functioning well.
Is there an issue with the motherboard, the processor?

NAS is on 24/7

Thanks a lot!

The error relates to an IDE drive so not sure how that affects the RAID? In that case it's most likely cable related.

In cases like that, when I'm not clear on the exact cause of a problem, I do the following:

1. Re-seat all connections - RAM, cables, plugs, etc. and clean if necessary.
2. Run memtest. That checks the RAM, CPU and other key components. Allow memtest to complete 3 or more passes before assuming all is well. Overnight is even better. Intermittent heat-related problems can often show up here.
3. Run OEM Disk diagnostics to verify drives, controller, cabling is in shape.
4. In NASLite admin, run check and repair with bad block testing for each individual drive. Bad block testing is irrelevant for a RAID array, so disable that for those.

Those are the 4 basic steps that can provide you with a pretty accurate indication of where your hardware stands. If you have any doubts about your machine, go through the above and if all is well, you can be assured you have a fit server.

Obviously, if a problem occurs during any of the test stages, I'd deal with it accordingly.

Hope that helps.

The only IDE drive in the computer is a Transcend 32 MB solid state module, directly mounted on the IDE connector. That's the boot drive, and booting goes flawless, it seems.

I'll take your suggestion to re-seat all connections.

Is this utility CD a good tool for the tests: http://www.ultimatebootcd.com/

Thanks for answering.

In that case the error is benign and caused by lack of UDMA.

It may well be that the NASLite drivers don't like that card. If the disk checks are OK (yes, the Ultimate Boot CD should do fine), then I'd say the card may not be usable with NASLite. I use two VIA SATA controllers in one of my NL servers without an issue, so who knows. Hopefully your tests will turn something up.

I think you're starting to confuse two issues: firstly there's a VIA Sata card, not functioning very well. I took that card out, and will test drive the villain in another setup. Secondly there's an issue with an IDE drive. The only IDE connected devices are a new CD drive, and the already mentioned Transcend Module.

The Transcend module has successfully been my boot drive for about 3 years in every NASLite box build. That should rule out a basic problem. Of course there could be a problem with this particular module.
Do I understand well that these lines:

indicate an IDE problem? And could that be the solid state boot drive?

This is the end of the syslog of another 2.62 system with the same Transcend boot drive:

Is there a clue when you compare the two?

And, BTW, the problem started with a degraded RAID array. That could not be related to a faulty boot drive, could it?

No confusion here at all.

The IDE drive you have is flash and does not support UDMA. The error simply indicates that the system drops down to PIO after failing to access the flash drive with UDMA enabled. You can probably take care of that in the BIOS by disabling UDMA for that IDE channel.

The rest of the issues are subject to your tests. I have no info to contribute on the degraded RAID or the performance of the VIA card.

What I can say with certainty is the particular hda errors are unrelated to the RAID and VIA card issues.

Thank you so much.

It has been said before, but it is so wonderful that you keep looking at the forum, and keep providing your answers.

I followed the advice to disable UDMA in the BIOS. But nothing changed. This is the endsection of the syslog where the Transcend device is discovered:

Anybody out there have a guess? Should I -in stead of disabling UDMA- enable the lowest speed in the BIOS, for instance?

Ignore it, it will always be in the syslog with a flash device, since it's doesn't support DMA.

Sorry Ralph, that's too easy. Here's the end section of my own test system, with the same Transcend device (http://www.transcendusa.com/Products/ModDetail.asp?ModNo=26&LangNo=0&Func1No=1&Func2No=159, no problems whatsoever:

It's just puzzling me.

So what changed?

And now I ask the question, if board/bios can't detect properly a boot device that has limited or no DMA support, how does that affect your running NL system?

OK, you have an old car, running absolutely perfect. All of a sudden, it dies. Your mechanic arrives, readjusts some parts, wiggles some cables and EUREKA! It runs again like before. Then you notice the red warning light on your dashboard. The manual instructs you to go straight to a garage. That's what you do, of course. You consult your kind & capable car mechanic again. He says: 'What's your problem? The car is running fine, ain't it? Just ignore the light. It's nothing"

I assure you, you keep looking at the light, and keep wondering: it wasn't there before....

Well, let me try to explain.

What you are seeing is the kernel doing its job. In some cases, where the BIOS properly sets the hardware, the kernel sees a PIO mode IDE device hence addresses it in those terms. If however the BIOS misrepresents the device and leads the kernel to think its addressing an IDE device capable of UDMA support, the kernel will proceed accordingly and fail issuing the error. It will then drop a notch and try addressing the device via PIO. That's why you see the error only once.

In the case of DOS/Windows, etc, the BIOS controls how the drives are addressed. In the case of Linux however, the kernel probes and handles the hardware based on it's capabilities and not necessarily by what the BIOS reports.

The DriveStatusError issued by the kernel is not new but has surely been there for that particular board. You can verify that by trying any version of NASLite including older versions.

Thank you for your comprehensive explanation. I do wonder if the previous version reported the same error. I don't recall seeing an error with the initial CORE3 on that machine.

I will have the computer second half of this week for testing, and will report my findings. Can I downgrade NL-2 the same way I upgrade (the 'i' option)?
