第一篇笔记仅仅是安装了pve，并且添加了cockpit和docker，这篇配置存储部分。
我的服务器目前是1块120G固态，上次已经装了系统。
还有2块320G机械盘、2块500G机械盘。
我们未必每次都能使用全新的硬盘，那么旧硬盘在ZFS或PVE当中都是不能直接发现的，它怕你误操作把有数据的硬盘给洗白白。
看我现在就是挂的几块用过的硬盘。
这些硬盘PVE默认不作为新硬盘给你用。需要重新初始化一下。
dd if=/dev/zero of=/dev/sd[X] bs=1M count=200
X代表你要初始化的磁盘。
根据我的情况：
root@pve01:/dev# dd if=/dev/zero of=/dev/sdb bs=1M count=200 200+0 records in 200+0 records out 209715200 bytes (210 MB, 200 MiB) copied, 1.53484 s, 137 MB/s root@pve01:/dev# dd if=/dev/zero of=/dev/sdc bs=1M count=200 200+0 records in 200+0 records out 209715200 bytes (210 MB, 200 MiB) copied, 1.6981 s, 123 MB/s root@pve01:/dev# dd if=/dev/zero of=/dev/sdd bs=1M count=200 200+0 records in 200+0 records out 209715200 bytes (210 MB, 200 MiB) copied, 2.16789 s, 96.7 MB/s root@pve01:/dev# dd if=/dev/zero of=/dev/sde bs=1M count=200 200+0 records in 200+0 records out 209715200 bytes (210 MB, 200 MiB) copied, 2.1021 s, 99.8 MB/s root@pve01:/dev#
PVE可以看到 硬盘了。
反正我也不知道为什么PVE的web界面无法创建ZFS。
我们用命令行来创建：
先看帮助：

sdb 500G 机械

我会告诉你 最近几天我装了几遍PVE么？不会。
但是我会告诉你，我在使用UEFI引导XFS格式的6.2版PVE，会出现关机时拔掉硬盘电源线或数据线，再插上，会出现无法引导的故障。
现在我在使用传统逻辑bios引导的PVE。

原来的文件还都在的。
其实这是迁移ZFS当中的导入操作。可以完整的将一组ZFS存储池，通过变更接线，甚至搬迁硬盘的方式将一组ZFS存储池变更到另一个主机上。
