我不小心将镜子的两侧分配给同一个物理设备。该驱动器出现故障，我已经从几个丢失的文件中恢复了。
这是游泳池：
# uname -a
FreeBSD nas.d20int.d20hobbies.com 13.1-RELEASE-p3 FreeBSD 13.1-RELEASE-p3 GENERIC amd64
# zpool version

zfs-kmod-2.1.4-FreeBSD_g52bad4f23
# zpool status tank
pool: tank
state: DEGRADED
status: One or more devices has experienced an error resulting in data
corruption. Applications may be affected.
action: Restore the file in question if possible. Otherwise restore the
entire pool from backup.

这些命令会产生以下错误：
# zpool detach tank 17044230459986981390
cannot detach 17044230459986981390: no valid replicas
# zpool remove tank 17044230459986981390
cannot remove 17044230459986981390: operation not supported on this type of pool
# zpool remove tank mirror-4
cannot remove mirror-4: Mount encrypted datasets to replay logs.
这池未加密。错误就是错误。此选项不会产生不同的sysctl vfs.zfs.zil.replay_disable=1. kstat.zfs.misc.dbgmsg 内核消息缓冲区中没有显示相关错误。重新启动没有问题（它恢复正常），但不能解决问题。
我开了一个openzfs 上的票证，但没有人回应。
有没有办法进一步解决这个问题？或者以其他方式删除 SLOG 而不恢复？
