从“FAULTED”zfs 池中恢复。“-F”选项似乎被忽略了

在 Ubuntu 上，我最近开始在外部 USB 硬盘上试用 ZFS。我现在似乎有一个损坏的 zfs 池，这可能只是因为我关闭了我的计算机（使用poweroff）。

$ zpool import
   pool: zfs
     id: 1234512345123451234
  state: FAULTED
 status: The pool metadata is corrupted.
 action: The pool cannot be imported due to damaged devices or data.
    The pool may be active on another system, but can be imported using
    the '-f' flag.
   see: http://zfsonlinux.org/msg/ZFS-8000-72
 config:

        zfs                      FAULTED  corrupted data
          usb-Disk_Name_etc-0:0  ONLINE

尝试导入它时，我收到一条有用的消息，说明我将丢失大约 1 秒的数据（这很好），我可以尝试使用“-F”选项进行恢复：

$ zpool import zfs
cannot import 'zfs': I/O error
    Recovery is possible, but will result in some data loss.
    Returning the pool to its state as of Thu 12 Mar 2020 00:58:03 GMT
    should correct the problem.  Approximately 1 seconds of data
    must be discarded, irreversibly.  Recovery can be attempted
    by executing 'zpool import -F zfs'.  A scrub of the pool
    is strongly recommended after recovery.

使用空运行标志，我确认 -F 应该工作：

$ zpool import -Fn zfs
Would be able to return zfs to its state as of Thu 12 Mar 2020 00:58:03 GMT.
Would discard approximately 1 seconds of transactions.

但是，当我尝试真实的东西时，它似乎完全忽略了“-F”选项并重复了原始消息：

$ zpool import -F zfs
cannot import 'zfs': I/O error
    Recovery is possible, but will result in some data loss.
    Returning the pool to its state as of Thu 12 Mar 2020 00:58:03 GMT
    should correct the problem.  Approximately 1 seconds of data
    must be discarded, irreversibly.  Recovery can be attempted
    by executing 'zpool import -F zfs'.  A scrub of the pool
    is strongly recommended after recovery.

我发现从这个答案中提到了“-X”选项：https ://serverfault.com/a/645866/74394但我继续收到完全相同的消息。我已经尝试了所有这些选项组合，包括池名称 (zfs) 和数字 ID 号（如 1234512345123451234），我总是得到与上面建议使用 -F 选项完全相同的消息。

-F -FX -f -fF -fFX

我在这里做明显错误的事情吗？如果我因为系统关闭而导致 1 秒的数据丢失而无法挽回地丢失了整个磁盘，那么 ZFS 似乎非常不稳定！我没有池的备份副本，因为我才刚刚开始尝试 ZFS。谢谢你的帮助。
