    After adding a disk to the pool, you may find disk corruptions.

    You can try to restore the file or just delete it.
    ```
    zpool status -v
    ```

    You can try to restore the corrupted files or just delete them if they don't matter.

    Then you have to try to scrub the pool:

    ```
    # this will try to repair everything (do this after deletion or restoration)
    zpool scrub rpool
    # when all errors are finally repaired or dropped, do this to clear the state of the pool
    zpool clear rpool
