Hi I recently moved to internal boot and transferred my License from USB to TPM.

Can a virtualized Unraid read my TPM to confirm proppe Licensing or what do I have to do?

Background:
Unfortunately after upgrading to 7.3 I'm experiencing problems with Thunderbolt. Unraid is not only a server for me, I run my daily and gaming VM on it using iGPU and dGPU passthrough. My monitor is attached via USB4/Thunderbolt and keyboard and mouse are attached to the monitor's internal KVM. This setup worked fine for more than 1.5 years without issues.
Since the Upgrade to 7.3.1 my Thunderbolt attached monitor remains black and mouse and keyboard are dead. I can see the login screen on my secondary monitor though so I know the daily VM is running just fine. This is a Thunderbolt issue and since Thunderbolt and Unraid is not exactly a match I would like to virtualize Unraid on Proxmox and move off all the Containers and VMs to Proxmox and just use the virtualized Unraid as NAS.
This would at the same time give me a 3rd Proxmox node and would allow me to use CEPH.

Nope, TPM only works with a bare metal install, you can stil use an internal boot pool, but will need to keep the flash drive for licensing.

OK, thanks!
This means I have to transfer the License back to the USB drive and then passthrough the USB correct?

One more question to avoid loosing data. Unraid is agnostic to where the drives are connected right? As long as It finds all the drives with the correct UUID I should be fine correct? I'm asking because currently my drives are connected to the motherboard's SATA port and I cannot passthrough all of them. Therefore I'm going to buy an HBA 9400-16i for passthrough and attach all the drives including Unraid Boot drives, cache and array disks there. Are there special steps I have to do? Unfortunately I cannot backup everything, I do not have enough storage.

Correct, and it will need to be a new flash drive.

Should be fine as long as the controllers are being passed through and the devices have their original IDs.

Thanks. But I guess in case this does not work and I have to rollback to running Unraid on bare-metal that I cannot use my motherboards TPM anymore right?

Do you know where the disk IDs are coming from or how they are generated? Is this some sort of math e.g. on the serial number of the HDD?

This

EDIT: So your controller has to pass the serial number through. Most of the strictly HBA ones do but be careful as RAID controllers often do not.

Yes, I'm aware that I will have to flash IT mode on the 9400-16i Controller. Thank you!

You can use it again, TPM is not permanently blacklisted, unlike flash drives.

Thank you both very much for your help!
