October 22, 20169 yr After a reboot, I ran a parity check which has slowed to a crawl and not sure why. One possibility is that the recently released Seagate IronWolf 10TB drive that I'm using as parity drive wasn't ready for primtetime--totally cop to living on the edge there. Screenshots and diagnostics file below. I'd appreciate any insight as to what might be causing the problem!

October 22, 20169 yr Reseat all the sata & power connectors (both ends) to all the drives. ATA10.00 is being continually reset, but the syslogs don't go back far enough to tell which drive is connected to it, so could be any of them
October 22, 20169 yr Community Expert You may want to improve your disk cooling, 60C is usually max operating temp for most disks, and you don't want to be anywhere near that, try to keep all disks < 45C
October 23, 20169 yr Author Thank you both for the help! Squid: Your solution was right on point. After I reseated all the connectors, booted, and did a parity check, parity check seems to be running at normal speeds! johnnie.black: Great point about the cooling. You made me realize that one of the front fans wasn't getting enough power to automatically start with reboots. I fixed that and the temps are much better now. Thanks again!
