Data and Parity 2 read errors, check OK w/self-test, rebuild then fail again

[pepar]

I have an array with 5 data disks and two parity disks. Several days ago just after it would have Moved data overnight, disk 5 and Parity 2 had red x's. Stopped array, ran long self-tests and both passed. Added disk 5 back into array and successfully rebuilt. Then added parity 2 back and BOTH it and disk 5 had read errors/failed. I repeated all of this two times. My array also has a hot spare that I used as parity 2 the THIRD time. Same results. Disk 5 rebuilds properly. I add the spare as parity 2 and again, the new and perfectly operating disk that is parity 2 AND the disk 5 fail.

 

I'd do it again, but the definition of insanity came to mind. I am out of ideas.

Post your diagnostics zip.

Thanks.

Problem is likely the Marvell controller, these are know to drop disks in some situations/hardware config, get an LSI HBA instead.

[pepar]

You are referring to the onboard SATA controller?

 

I will be able to disconnect the six drives attached to the motherboard, add the HBA, reattach my disks and not lose data?

[JorgeB]

No, this one:

 

01:00.0 SATA controller [0106]: Marvell Technology Group Ltd. 88SE9230 PCIe SATA 6Gb/s Controller [1b4b:9230] (rev 10)

Where, and if I'm right not by coincidence, both the failed disks are connected.

Hmmm, I will look at that. That means my Highpoint 640L has a Marvell controller. I haven’t yet found what part is on the motherboard.

 

if I change controllers will I lose data or will unRAID read the disks and reintegrate them into the array?

Interesting. I've had a lot of trouble with Marvell-based SAS HBAs (I've replaced them now) but never with my 88SE9235-based SATA/e-SATA controller (similar to the 9230 but has no built-in RAID capability). I assumed that was because it used the standard ahci driver module.

Jumped on eBay and bought a fresh pulled LSI 9211-8i controller for $40 and two breakout cables for another $17.00. Guess I will never know why my Highpoint 640L took a crap, but that's what it *has* to be. Will know in about a week I guess.
