Read errors on disk 5 - SMART short self-test: passed

Greetings UNRAID community. I received the status report below via my email notifications. Disk 5 is active and seems to be working fine, but there are read errors documented in the attached log file. A smart short self-test passed. Do I need to stop and restart my array/dig deeper into the operation of disk 5 further? It's only ~3 months old or so. It's under warranty if I need to replace it. I believe what precipitated this was my UPS inexplicably powered off a few days ago. Parity was rechecked successfully after the UPS turned itself off.  There was no power outage with our electrical grid so not sure why the UPS powered off (working on that with CyberPower to figure out what happened there).

 

Here's the emailed report:
