我最近遇到了磁盘故障，为此我得到了一个替换磁盘，并成功更换了磁盘并完成了重新同步过程。我能够通过 samba 毫无问题地使用 raidz2，但随后按照 zfs 的提示清除错误，命令“冻结”并且没有输出。我让它过了一夜，由于早上仍然没有显示任何内容，我终止了命令，但仍然没有任何反应，所以我只是关闭了与它的 putty ssh 连接。此后，无论我尝试什么，我都无法访问数据、导入或导入池。
系统在 ubuntu（主机名为 UBUNTU-SERVER-KVM）上，我在其上安装了另一个虚拟 ubuntu（主机名为 ubuntu-server），它通常通过 samba 共享访问 zfs（我从未弄清楚如何让它在虚拟机中直接访问）。我怀疑我可能在主 ubuntu-kvm 上完成了部分 zfs 工作，在虚拟 ubuntu 安装上完成了部分工作。我担心这会导致我的问题，我无法以任何方式导入池。ubuntu-kvm 机器的 zpool.cache 显示“旧”池设置，其中有死驱动器，而不是新驱动器。这似乎证实了我错误地在虚拟 ubuntu 机器上执行了重新同步，而不是通常具有 zpool 的 ubuntu-kvm。
我有一种感觉，如果我能以某种方式纠正池尝试导入的路径，我的数据仍然会在那里，因为重新同步过程已完成，我之前能够访问它。虚拟 ubuntu 将其驱动器称为“/dev/vd*”，而托管虚拟机的 ubuntu-kvm 将它们显示为“/dev/sd*”。
有人知道我下一步该怎么做才能恢复数据吗？是的，我确实在云端备份了最重要的部分，但还有很多其他东西丢失了，我宁愿它们没有丢失 :)
以下是一些希望对您有帮助的信息：
