January 8, 20233 yr Hello all and thanks in advance for any help, I'm having a bit of a weird problem with drives over 4tb. For the last year or so I've had an 8tb and 5tb drive as my parity drives, the largest other drives being 3tb. A couple weeks ago, both parity drives seemed to have failed one after the other with errors trying to read/write. I finally picked a pair of new 10tb drives and replaced them, and have the same issue, they seem fine for half an hour in to a preclear, or parity rebuild, then error out. Just for the heck of it, I tried an old 4tb drive I had and it works just fine. My best guess at this point is that something is wrong with my HBA, but I thought I should see if there is anything else I should check or do before ordering a new controller. Currently running version 6.8.3 (planning to update but didn't want to mess with it without the array in good health) Supermicro H8DA3-2 (dual six-core Opteron 2435) LSI 9210-8i HBA for drives over 2tb Running 25 data disks mostly through LSI sas 1 controllers and an HP Expander. All the data drives work fine. All the drives except two are 2tb or less. Two are 3tb that were previously my parity drives until replaced with the 5 and 8tb ones last year. The machine reads the other 3tb drives without a problem, but throws read/write errors with the 5tb, 8tb, and two 10tb drives. I've tried swapping cables about and the problem follows the drives, not the cables. As a side note, the sata on the mother board have never worked right, dropping drives. I originally used them for the larger parity drives, but had too many issues so stopped using them. I tried that with the new drives, and had the same issues so have given up on using those ports.

January 8, 20233 yr Author I'll go ahead and do the update, but not sure that this would explain it previously working and now not working?
January 8, 20233 yr Author The firmware update may have solved the issue. An hour in to a preclear without any issues yet. The help is much appreciated. Still unsure why it was working in the past.
