[253981.512570] sd 5:0:0:0: [sdf] [253970.368375] Add. Sense: Unrecovered read error - auto reallocate failed [253970.368380] end_request: I/O error, dev sdf, sector 5680577752 I'm confused. The above happens twice. So it seems clear the problem is with /dev/sdf and sector 5680577752. Since it's an AF drive, technically sectors 5680577752 - 5680577760 are affected, since those are the LBA's for a single physical sector. However, all of the "read error corrected" that follow have completely different values, 5478837464 through 547883753. And then 3 seconds later another read error at the same LBA: [253977.980604] sd 5:0:0:0: [sdf] 253977.980605] Add. Sense: Unrecovered read error - auto reallocate failed [253977.980612] end_request: I/O error, dev sdf, sector 5680579352 and 4 seconds later [253981.512576] sd 5:0:0:0: [sdf] [253981.512577] Add. Sense: Unrecovered read error - auto reallocate failed [253981.512582] end_request: I/O error, dev sdf, sector 5680579352 And then "read error corrected" 5478839064 through 5478839136 which are different than the first batch. So there's a single LBA reported by libata as URE multiple times, each with identical address. But then two corrected events, each with a different range of sectors, neither of which match the URE address. ??
