If using btrfs: sudo btrfs scrub start / watch -n 10 sudo btrfs scrub status / #optional That'll read every data and metadata block. Corruptions are reported in dmesg. If there's redundancy (e.g. dup or raid1+) it'll try to repair it from a good copy. Without a scrub, the same error detection (and fixups if possible) happens passively as blocks are read. -- Chris Murphy _______________________________________________ devel mailing list -- [email protected] To unsubscribe send an email to [email protected] Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/[email protected] Do not reply to spam on the list, report it: https://pagure.io/fedora-infrastructure
