I should have mentioned that I have at least 5,000 of those read errors, maybe more because my syslog was full. I have increased my syslog size and it will be permanent upon the next reboot.

How do I fix a power/connection issue? FYI, the power supply was recently replaced because it went bad.

Attached wrong file on initial post, here is the Diagnostics file attached. Thank you trurl. descartes-diagnostics-20251223-0724.zip

Any help is much appreciated, Unraid newb for the most part here. Getting these errors in syslog: kernel: md: disk0 read error, sector=736711744 Fix Common Problems says: Can it be determined if the Parity disk is bad or it is the cabling? If it is a bad disk should I wait to replace it because I am in the process of replacing a data disk and it is still preclearing (taking forEVER)? If it is a cabling issue is it recommended to just replace the cable? I have checked that the connection is tight. Diagnostics attached. TIA descartes-smart-20251223-0815.zip
