[SOLVED] hdparm on proxmox host or inside vm

[TheHellSite]

I would like to disable the disk spindown of a hard drive, that I is connected to my nas vm using passtrough.

Do I have to configure hdparm on the proxmox host or inside the vm?
Which system is taking control of this now?

Kind Regards

How did you pass through the disk?

Exactly, as stated in the documentation.
1. https://pve.proxmox.com/wiki/Passthrough_Physical_Disk_to_Virtual_Machine_(VM)#Short_List
2. https://pve.proxmox.com/wiki/Passthrough_Physical_Disk_to_Virtual_Machine_(VM)#Update_Configuration

I hope this is still the recommended way of doing it?

Okay, So the way that you have a scsi2: /dev/sdX in your VM config right? That means that the host is still responsible for the disk and you probably should run that hdparm command on the host.

Yes!

That means that the host is still responsible for the disk and you probably should run that hdparm command on the host.

What I would prefer however is that the vm is responsible for that.
How can I achieve this?

You would have to pass through the whole disk controller to the VM with PCI passthrough. If you use the onboard controller for the disk and/or have other disks connected to it as well, this will not work.

I understand. Thank you very much!
