Cam errors (ICRC ABRT ; drd serv err)

[Arjan]

Dear experts,

After playing around with old Freenas builds (0.5; 05; 06 ; 07) on a, now broken down server, i now started to build a new Freenas system on a cute little Dell SC1435 server.

The exact config you find in the signature.

Here is this problem i am encountering:

The machine gives permanent CAM-errors on the ada0-drive, but stays up-and-running.

This ada0 is a sata converter for a 4GB Sandisk CF-card, and is connected to the regular sata-port on the motherboard.
This flashcard is used to boot the freenas build from.

Can anyone please help me, with explaining the errorcodes, i receive ?

Thanks,

Arjan

Your flash media is taking too long to be accessed and its causing those errors. While that error can be safely ignored, the problem is that the media is so slow it could cause data loss later. That's obviously bad and needs to be corrected.

Not sure which Sandisk Ultra you have, but the issue could also be with your CF to SATA converter not being a good quality or is going bad. Do note that the throughput of your CF card may not be the problem, but the latency between reads and writes may be the problem. Normally, I'd think that any Sandisk Ultra CF card would be acceptable for this use, so I'd eyeball the CF to SATA converter first.

Thanks Cyberjock,

I hoped for a fix in some of the settings, but your answer is loud 'n clear, and i'll go after the cf-card to sata converter and/or the card itself. (Sandisk 4g with 30 Mb/s.)

Fact is, that the converter is some cheap Chinese card, and that the CF-card (now i'm thinking of it) is several years old.

Think i'll switch to a usb-stick to boot from, and see what is happening then.

Regards,

Arjan

Honestly, I'd think that your CF card would be more than adequate for your function. Of course, the cost of buying a good quality CF card to SATA converter is probably more than a USB stick.

I use Corsair Voyagers and never had a problem! http://www.newegg.com/Product/Product.aspx?Item=N82E16820233037

And in the end, swapping the sata-cable did the trick........;)

Interesting! I didn't even think of that to be honest.

Good try!
