我有一个由 8 (6/2) 个驱动器组成的 ZFS 池，在我的服务器断电约 5 天后，我创建的 zpool 不再显示我将其挂载到的位置。当我第一次访问服务器时，我必须运行sudo /sbin/modprobe zfs才能运行zfs list或zpool status。

$ zfs --version
zfs-2.0.7-1
zfs-kmod-2.0.7-1

$ uname -r
4.18.0-348.20.1.el8_5.x86_64

我尝试以下命令来尝试导入 zfs 池：

$ sudo zpool import -D -f tpool
cannot import 'tpool': no such pool available

$ sudo zpool import -a
no pools available to import

$ zfs list
no datasets available

我可以运行 zdb 并得到：

$ zdb

所以我知道驱动器仍在，池仍已形成（我在 Avago 实用程序中也看到，当我启动服务器时，所有驱动器都存在）。但是lsblk只返回运行服务器的主 SSD。

所以我不知道在断电后该做什么或如何恢复我的 zpool。关于我接下来可以做什么/运行什么或我还可以做什么来解决这个问题，有什么想法吗？

$ sudo /sbin/modprobe zfs另外为什么每次重启后我都必须继续运行？
