Physical Hard drive Pass through with physical attributes and without emulation

[neail]

Hello, first of all, apologies if that question makes no sense to anyone.

I am VMing Open media vault (OMV) inside PVE, I have a couple of NTFS drives that I want to backup in a larger drive with EXT4, fortunately, OMV supports both file formats.

Recently, I have been using VirtIO to passthrough my drives to the VM, but the problem was there were no SMART data available to the OMV as the disk were virtualized,
Next tried the SCSI passthrough, as that was also virtualized by qmeu a little bit more data available but full SMART access was not possible.



Can anyone, please suggest any way that the SMART data can be accessed from INSIDE the VM?







(commands if someone finds it helpful)

first discover the disks in proxmox shell with-

 ls -n  /dev/disk/by-id/


for VirtIO passthrough- (if multiple drives, keep changing the virtIO number like virtio3, virtio4.... )

/sbin/qm set "VM id in number " -virtio3 /dev/disk/by-id/"Disk id by ata/scsi/wwn "

example code---
/sbin/qm set 100 -virtio3 /dev/disk/by-id/ata-ST3500413AS_Z2A4RXV0


for SCSI passthrough-

qm set "VM id" -scsi2 /dev/disk/by-id/"disk-id"

I have the same problem.

I have the same problem.

Use PCIe passthrough of a whole drive controller, which comes with a whole new set of caveats. Or consider using a container.

Hi, actually those are chipset controlled drives... Still I would very much love to pass through the HBA... Thank you for the suggestion.
