See the btrfs-device manpage, stats subcommand, -z|--reset option, and device stats section: -z|--reset Print the stats and reset the values to zero afterwards. DEVICE STATS The device stats keep persistent record of several error classes related to doing IO. The current values are printed at mount time and updated during filesystem lifetime or from a scrub run. So stats keeps a count of historic errors and is only reset when you specifically reset it, *NOT* when the error is fixed. (There's actually a recent patch, I believe in the current dev kernel 4.20/5.0, that will reset a device's stats automatically for the btrfs replace case when it's actually a different device afterward anyway. Apparently, it doesn't even do /that/ automatically yet. Keep that in mind if you replace that device.) -- Duncan - List replies preferred. No HTML msgs.
