这是我第一次尝试在 Proxmox 下手动创建 zfs 池。
我创建了一个包含 5 个驱动器（4 个 WD RED 1TB NAS 驱动器和 1 个旧的 1TB Seagate）的 raidz2 zfs 池。我还忘记指定 2 个备用驱动器，因此池中最终有 5 个驱动器。其中一个硬盘停止正常工作（有时显示为 FAULTED，有时显示为 UNAVAIL），池降级。

我还创建了几个子目录，以便将数据与虚拟机分开（例如：/storage/share/iso。/storage/share/Movies...）
storage/share 将由 VM 通过 NFS 挂载和共享。storage/vmstorage 是存储 VM 的地方。

storage/vmstorage/subvol-108-disk-0 795M 7.22G 795M /storage/vmstorage/subvol-108-disk-0
我能够从网络访问共享文件夹并将其用作普通网络共享，没有任何问题，直到磁盘损坏。/storage/share/* 下的一些数据消失了。虚拟机很好。
即使在降级模式下数据是否仍然可以访问？
谢谢你的帮助 ！
答案1
存储/共享数据集不知何故被卸载。再次安装 zfs 数据集即可解决问题！
