November 1, 201510 yr Hi, I recently replaced a failed drive and all seemed to be good. There are no issues reported and the array/disks are all reporting healthy. No errors on a partiy check. My syslog, however, is contantly churning with this... Any ideas?

I can post portions if needed. ridcully-diagnostics-20151101-0836.zip
November 1, 201510 yr Sounds like you disturbed a cable to one or more of the drives when you replaced the other one, and its now a flakey connection. Check them all (power and sata)
November 5, 201510 yr Author I'd also recently tried docker (ember media server) and plex server. I've disabled both of those and everything seems to be fine now. Full parity check with 0 errors. Not sure if its a coincidence or not.
