Hello Albert, Have you check the hardware status of the involved drives other than with smartctl? Like with the manufacturer's tools / WebUI (iDrac / perccli for DELL hardware for example). If these tools don't report any media error (that is bad blocs on disks) then you might just be facing the bit rot phenomenon. But this is very rare and should happen in a sysadmin's lifetime as often as a Royal Flush hand in a professional poker player's lifetime. ;-)
If no media error is reported, then you might want to check and update the firmware of all drives. Once you figured it out, you may enable osd_scrub_auto_repair=true to have these inconsistencies repaired automatically on deep-scrubbing, but make sure you're using the alert module [1] so to at least get informed about the scrub errors. Regards, Frédéric.
