想要一个NAS，于是用上了TrueNAS，又想要虚拟化，无奈TrueNAS的虚拟化功能太弱了。于是在PVE上安装了TrueNAS，再将虚拟机安装到NAS上，达到all in one的目的，又能利用zfs的快照功能，加强虚拟机的安全性。

这个架构需要使用硬件直通+NFS。如果你的硬件条件不满足下面4个条件，个人建议不要尝试这个方案。如果你不需要将虚拟机存放到nas，也不需要尝试这个方案。

• 内存 ≥16G ---zfs吃内存
• CPU ≥i5 级别以上 ---zfs需要cpu去做计算，all in one得需要强力CPU
• 主板支持直通 ---zfs需要直接控制硬盘
• 主板支持nvme/或者有额外的sas/sata控制器/或者在U盘上装了系统 ---需要把硬盘直通给VM，所以需要一个系统盘。

一、方案

在PVE上新建TrueNAS虚拟机。同时创建2个网桥：

一个桥接到物理网口，以用于外部文件共享
一个不桥接任何网口，作为一个虚拟接口，用于TrueNAS和Proxmox nfs通信。（这个网口最高可以达到40G的带宽）

将非系统盘的硬盘控制器直通给TrueNAS，此时TrueNAS可以直接读取到硬盘，创建一个zfs池，再新建一个nfs共享，通过虚拟接口共享给PVE，作为VM的存储池。

 

二、本文实验环境：

类型	详细信息
CPU	QQLT
主板	华硕B150
内存	24G
板载SATA	3T*2
板载M.2	240G NVME(系统)
直通卡	m5110
直通卡硬盘	2T sas*4
PVE版本	7.0.9

三、开搞

1、创建2个网桥。

2、开启iommu

在/etc/default/grub的启动行，添加intel_iommu=on

随后进行update-grub，
再进行 ，update-initramfs -u，重启生效。

3、创建TrueNAS

创建的时候，建议使用UEFI和virio设备，同时添加2个不同网桥的网卡，一定要选Q35例下图

4、直通sata控制器给VM

添加PCIe设备

根据自己的需求，选择直通设备。反正不要把自己系统盘直通去了就行。注意，板载SATA名一般是芯片组+sata controller。

我这里要直通sata控制器和直通卡。再看一下配置

5、安装TrueNAS

记得选择UEFI，如果是传统模式，就要选bios

安装好重启就可以了。

6、配置TrueNAS，ip

计划是将正常的网卡配置局域网ip，将虚拟网桥接口配置到和pve一个网段的。

我这里正常的网口已经dhcp了，就直接上网页配置把

改成中文，修改了需要save一下。

进入网络配置网络接口

保存之后，如下

再选择test change，做更改

在pve上面，ping下这个truenas地址

虚拟接口链路是通的

正常线路也是通的。

这里使用iperf3 来测试一下虚拟接口的带宽。

在pve上安装iperf3，apt install iperf3 -y

root@pve3:~# iperf3 -s
-----------------------------------------------------------
Server listening on 5201
-----------------------------------------------------------

iperf3已经集成在了TrueNAS上，可以直接使用

这里测试结果出来了，有30G的带宽。非常优秀。

对于30G的带宽，预估要20块hdd才能达到。所以对于一般的用户来说，这个接口完全不会成这个方案的瓶颈。

7、创建ZFS池和nfs共享

我这里使用2块3T硬盘创建了一个raid1

8、在PVE上添加nfs储存

在其他主机上，复制一个镜像到nfs存储

使用scp复制，可以看到速度有100M/S，这是把我的千兆网跑满了。

 

9、安装虚拟机测试。

拉跨的4k速度

4K速度太拉跨了。

测试一下存储移动的速度。将虚拟机关机，移动磁盘到本地存储。

从测试结果来，顺序读写都有400M/S。算是把2块盘性能拉到顶了。

应该是大部分数据都写入到了内存，TrueNAS因为内存不足都已经卡死了。
