![降级的 zfs 池中数据丢失](https://linux22.com/image/1579278/%E9%99%8D%E7%BA%A7%E7%9A%84%20zfs%20%E6%B1%A0%E4%B8%AD%E6%95%B0%E6%8D%AE%E4%B8%A2%E5%A4%B1.png)
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。

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!
