May 4, 20188 yr 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. Jeff
May 5, 20188 yr Community Expert Problem is likely the Marvell controller, these are know to drop disks in some situations/hardware config, get an LSI HBA instead.
May 5, 20188 yr Author 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? Edited May 5, 20188 yr by pepar
May 5, 20188 yr Community Expert 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.
May 6, 20188 yr Author 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? Edited May 6, 20188 yr by pepar
May 6, 20188 yr 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.
May 7, 20188 yr Author 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.
