ZFS показал что у меня начал отваливаться диск

На рабочем компьютере, после очередного scrub, мне показали что с одним
из дисков не всё в порядке:

    # zpool status
      pool: zroot
     state: ONLINE
    status: One or more devices has experienced an unrecoverable error.  An
            attempt was made to correct the error.  Applications are unaffected.
    action: Determine if the device needs to be replaced, and clear the errors
            using 'zpool clear' or replace the device with 'zpool replace'.
       see: https://openzfs.github.io/openzfs-docs/msg/ZFS-8000-9P

    config:

dmesg, действительно, показывает ошибки:

Работал более десяти лет. Пора на покой. zpool detach, вставляем новый
диск, zpool attach, через какое-то время здоровенькое зеркало снова в строю.
