--- title: "PVE 迁移翻车自救" date: "2024-10-13" tags: - "折腾" - "PVE" canonical: "https://xxxuuu.me/post/pve-migration-rescue" --- 这两天刚购入了一台天钡 wrtpro 作为新 Homelab 和 NAS。到手后也安装了 PVE，打算组一个 PVE Cluster，将部分业务迁移到新机器上 但 PVE 这个 Cluster 功能非常不产品化，如果当前有任何 LXC 或 VM 正在运行，就不能加入进 Cluster 中 官方论坛给出了一个方案，可以临时移走 `/etc/pve/lxc` 和 `/etc/pve/qemu-server` 下的配置文件，这样 PVE 就认为当前节点上不存在 LXC 和 VM 了，待加入 Cluster 后再恢复配置文件： - [https://forum.proxmox.com/threads/cluster-join-failed-this-host-already-contains-virtual-guests.55965/](https://forum.proxmox.com/threads/cluster-join-failed-this-host-already-contains-virtual-guests.55965/) 于是我就将配置文件都 rename 了一下，成功加入了 Cluster。而在 rename 回来的时候发现！！！配置文件所在的目录都被清空了！！！

总结一下，只要磁盘还在，数据就还能保住，只要恢复 LXC 和 VM 本身的配置文件即可，或者直接重新创建新的 LXC 和 VM，将磁盘挂载进去也行 从这件事也可以看出，PVE 在一些企业级一点的功能上还远不够产品化，自己操作上也不够谨慎，应该考虑其它的备份目录和方式 PS：最后，PVE 这个 Cluster 设计是没有 master 节点的，看起来只是单纯的 quorum 操作完成同步（查了下是基于 corosync 实现的），每个节点的所有 LXC 和 VM 配置都会通过 pmxcfs 同步到其他节点上，所以这也可能是加入集群后文件被清空的原因（配置文件夹在初次同步后被覆盖了）
