Hi, I've been running FreeNAS (now TrueNAS) for many many years now (although, I am still an amateur). I seem to have an issue with one of my disks:
1 Currently unreadable (pending) sectors
1 Offline uncorrectable sectors
However, I'm not entirely clear on what (if anything) needs doing here. I've searched historical threads for these errors and see people post the output of their smartctl report and get tailored advice. While I would certainly appreciate that (and have attached my report here) I'm also looking for some guidance that I can follow in general to help interpret what the numbers mean and the significance, so I don't have to create a thread asking for help if something else goes wrong in the future. Is there any such guidance available? I googled but couldn't find much. Thanks for any help and recommendations!
