我在ZFS机器中遇到了一个错误。 我的服务器掉电后，可能会发生这种情况，但我无法确定。 我的带有RAIDZ-1的ZFS Pool Gewuerzglas不再愿意导入。 尝试导入时总是遇到错误：
cannot import 'Gewuerzglas': I/O error Destroy and re-create the pool from a backup source. 我已经尝试了几件事情。 非似乎工作。 任何build议如何拯救这个池？ 由于所有的驱动器仍然在线，在我看来，数据可能仍然存在，但一些检查总结不好？
我到目前为止所尝试过的
root@openmediavault:~# zpool import pool: Gewuerzglas id: 15011586312885837941 state: ONLINE action: The pool can be imported using its name or numeric identifier. config: Gewuerzglas ONLINE raidz1-0 ONLINE sda ONLINE sde ONLINE sdj ONLINE sdc ONLINE sdg ONLINE sdf ONLINE sdi ONLINE sdh ONLINE sdd ONLINE

root@openmediavault:~# zpool import -f -F -n Gewuerzglas
不显示任何东西
当我将监视器连接到我的服务器时，我也可以制作此屏幕截图
任何人都知道如何修复或拯救数据？

我不明白为什么它告诉我，这些驱动器目前不可用，因为他们似乎没有。 我可以看到他们，我只是与所有的驱动器进行长时间的智能检查。
