Is anyone here using AMD RAID 1?

[mikeymikec]

I've got two customers' machines with SB750 chipsets that are dumping disks from their respective arrays without any obviously good reason why; the dumped disk checks out fine (SMART readings and a full chkdsk).

I have a sneaking suspicion that the default settings on AMD RAID Expert are to blame; there are settings available to schedule RAID synchronisations and disk checks but they're not enabled by default. The official online help isn't of any use in that it doesn't make any recommendations, so I've gone with 'media patrol' checks once a month and an array data sync once a week on both machines.

I've got one of the machines over the Christmas period so hopefully that will be long enough to monitor it for any abnormal behaviour.

One of the machines actually has some AMD RAID errors in the event log:

Task 30 disk error on port 1 target 1 at LBA 0x066649a (Length 0x76)  with status 30; Error register: 0

A string of these in a row, IIRC immediately before the disk was dumped, the only difference in the errors was the LBA and length values. The official help guide doesn't give any guidance with regard to this error and I haven't found anything online that matches it.

I just think both arrays dumped disks because they ran too far out of sync, and without any checking systems in place, that was inevitable.

That error message looks suspicious of bad sectors on one of the drives. Have you tried checking the SMART data on the disks to see if they have recorded any bad sectors?

LBA and length values

On the next reboot MS Win will fix it.

What gets me is the WAR between AMD/ATi and Samsung praising Intel in Sun Shine.

I gotta give nVida koodo's for abstaining.

Worst thing that happened is when AMD bought out ATi.

Recall the dominance of the nForce 2 & 4 MB chip sets and even ATi got into the act to run Intel CPU's faster. Look what happened to VIA.

Technology is a dog eat dog consumers market of Co-operate share holders Vs elective Politicians forsaking Humanity. The demolition of ATi is a typical example of Canadian's being smothered by foreign currency, similar to our lost of the AVRO Arrow. Printing more and more foreign currency, such as the US Dollar, dominates mans lust for power.

Look at the value Ruble today, The Balkans, Ukraine and Crimea, we are all pheasants, without the right to live. in the face of the bond between Politicians and Co-operations.

What is this over powering need to subdued the BEST - If it where not for Greed, Money and Power - Absolutely Useless to me.

Excuse my RANT ;o)

There's a different error for bad sectors, believe me I've found that one

There's also a bad sector log in AMD RAID Expert (BSL Log) for each drive, nothing logged.

Though one thing I'm pondering doing is ejecting the disk that AMD RAID considers to be the better one (ie. the one that hasn't been ejected before) and checking it thoroughly with it connected to my PC. If that disk turned out to be the problem, that would seriously undermine any confidence I have in AMD RAID.

what kind of drives are you using? maybe your drives are going to sleep and getting kicked out of the raid?

I had that problem with Intel RAID once so I've tried disabling it here, though the symptoms were very different (the Intel RAID system became unresponsive as soon as the disks powered down).

I strongly suspect that the disks were going out of sync because the RAID software wasn't bothering to check them at all on default settings. I would be interested in knowing what Intel RAID does on default settings.

As expected, both disks passed their first media patrol, and no problems have been cited on the (current) daily sync jobs. I probably will reduce the frequency of sync jobs to once a week after a few months.
