硬盘直通

在做硬盘直通之前，在trueNas(或者其他虚拟机)内是检测不到安装的硬盘的。

在pve节点查看硬盘信息

打开pve的shell控制台
在这里插入图片描述
输入下面的命令查看硬盘信息：

ls -l /dev/disk/by-id/

该命令会显示出实际所有的硬盘设备信息，其中ata代表sata盘，类似的还有nvme等

我本次要进行硬盘直通的是如下两条记录：

lrwxrwxrwx 1 root root  9 Feb 17 21:19 ata-ST4000VX013-2XG104_WFN816PA -> ../../sda
lrwxrwxrwx 1 root root  9 Feb 17 21:19 ata-ST4000VX013-2XG104_WFN816TB -> ../../sdb

ata-ST4000VX013-2XG104_WFN816PA与 ata-ST4000VX013-2XG104_WFN816TB是对应的硬盘id。

硬盘直通

硬盘直通命令的格式为：

qm set <vm_id> –<disk_type>[n] /dev/disk/by-id/<type>-$brand-$model_$serial_number

这里涉及到了几个参数：

vm_id：填写虚拟机的id，例如我要给trueNas的虚拟机做直通，则取100
disk_type：直通模式，一般取scsi+0~10等
- $b r an d -$ model_$serial_number：直接填写硬盘id就好

我要挂载两个盘，所以此处使用两个命令:

1、qm set 100 -scsi1 /dev/disk/by-id/ata-ST4000VX013-2XG104_WFN816PA
2、qm set 100 -scsi2 /dev/disk/by-id/ata-ST4000VX013-2XG104_WFN816TB

分别在shell中执行上述两个命令：

root@pve:~# qm set 100 -scsi1 /dev/disk/by-id/ata-ST4000VX013-2XG104_WFN816PA
update VM 100: -scsi1 /dev/disk/by-id/ata-ST4000VX013-2XG104_WFN816PA
root@pve:~# qm set 100 -scsi2 /dev/disk/by-id/ata-ST4000VX013-2XG104_WFN816TB
update VM 100: -scsi2 /dev/disk/by-id/ata-ST4000VX013-2XG104_WFN816TB

此时在trueNas中已经可以显示这两块硬盘
