Should I be worried?
(lemmy.ml)
No need to worry, disk failures almost never result in fires or hazardous conditions.
A-yuk-yuk-yuk.
Seriously: you have a disk that has failed, based just on that little snippet of the logs, internally (ICRC ABRT). You can either use a tool like spinrite to try and repair it, but you may lose all the data in the process, or replace it.
A user suggested bad cabling and that’s a possibility, one you can check easily if the error is reproducible by swapping the cable. Before I swap cables often I’ll confirm the diagnosis using smartctl and look for whatever the drive manufacturer calls the errors that happen between the media and disk controller chip on the drive. If it has those then there’s no point in trying a cable swap, the problem is not happening there.
People will say that you can’t “fix” bad disks with tools like spinrite or smartctl. I’ve found that to be incorrect. There are certainly times when the disk is kaput but most of the time it’ll work fine and can go back into service.
Of course, that’s recovering from errors when I get an email or text the first time and going back to service in a multi-parity array so lowered criticality and early detection could have lots to do with that experience.
