I've just upgraded my CPU (ryzen 5 1800 to ryzen 9 5900) , and upon boot I now have the following message

"We detect a new processor, which will change the dada/structure of the storage space for firmware TPM. If you did not apply this function, please press Y to continue, otherwise please follow instructions below:

Press Y to reset fTPM, if you have BitLocker or encryption enabled, the system will not boot without a recovery key.

Press N to keep previous fTPM record and continue system boot, fTPM will not enable in new processor. You can swap back to the old processor to recover TPM related keys and data."

I tried to pressed N and the machine boot correctly (and the array/shares/docker where ok), but the message keep appearing after a reboot.

I do have an encrypted array but I'm pretty sure that this message do not apply to my case, but I'm not experienced enough with those things to press Y without more information/advice.

Does anyone had this kind of issue, and is it safe fore me to press Y?

Thanks to all.

This is a very good question. I disable tpm by default on everything i have and i do run encryption on unraid. Im very certain that LUKS in unraid doesnt make use of the tpm but i cannot answer that with full certainty.


Edit:

@JorgeB might have a definitive answer to that

Same, pretty sure it's not used, and if it were, I think it would auto decrypt the array on boot, that's what BitLocker and TPM do, user doesn't need to decrypt the device during normal Windows boot.

I didn't think that TPM was used either, but I'd rather ask before doing something too quick,

I just rebooted and pressed Y and everything seems to work correctly.

Thanks for your time.
