Hello Steve, As some of the other responders already said, check your drives' SMART values. But a disk may fail without any indication in the SMART table. I've seen this a couple of years ago and documented it here: https://www.claudiokuenzler.com/blog/301/disk-failure-not-detected-by-smart-ata1-failed-command The errors you've seen are also kind of similar as the ones I saw (although there are a couple of years in between, so Kernel messages might be a bit different now).
Long story short: It was indeed a defect hard drive causing the problems (and log entries).
