WARN: no efidisk configured! Using temporary efivars disk.

[nycrush]

I switched my NVME drive from one pci slot to another. now my ubuntu VM is giving me an error. WARN: no efidisk configured! Using temporary efivars disk.
please help.
thank you

Can you please post the output of cat /etc/pve/storage.cfg, cat /etc/fstab and mount?
My guess is that the disk does not get mounted correctly and thus the efidisk image cannot be found.

Are there maybe any other warnings/errors in the journal (journalctl -b -e)?

Hi together,
I'm going to roll up this topic once again. However, it is a slightly different case for me.
I have created a VM without EFI DISK. Now, every time I start this VM, I get the error message already mentioned.

"WARN: no efidisk configured! Using temporary efivars disk.
TASK WARNINGS: 1"

Is it somehow possible to set the EFI DISK afterwards and what exactly do I have to do so that the VM boots properly again.

I just tried once to add an EFI DISK, however, the VM then no longer boots and I then unfortunately do not know what exactly I have to do.

Can anyone help me?

Thanks in advance.

after adding the EFI disk, I guess you need to add the correct boot option(s) to it, see: https://pve.proxmox.com/wiki/OVMF/UEFI_Boot_Entries

I have the same issue, resolved with adding a EFI disk afterwards and set up the correct boot order in the Options tab.

How do you add a EFI disk? and what disk is it supposed to be? sorry noob here!

 

[leesteken]

Go the the VM settings for Hardware. Click the Add button and click EFI Disk. It's not a real or virtual disk, it's just called that way. EDIT: Well actually, it is stored similar to virtual disk.

Hi and sorry for pushing up this thread again.
After a restart of my proxmox 7.3-3 due to a power loss, my OMV6 didn't start again.
My 'DATA' storage is not active anymore.
The logs shows one warning which - I guess - is the root cause "WARN: no efidisk configured! Using temporary efivars disk.".
And then an error appears: "zfs error: cannot open 'DATA': no such pool".

And of course, as always, there is important data on DATA.
I would really appreciate any help...

Hi,

The logs shows one warning which - I guess - is the root cause "WARN: no efidisk configured! Using temporary efivars disk.".

that error is not the real issue here, but just means you cannot make changes to your VM's UEFI settings persistent. Adding an EFI disk to the VM will fix that.

And then an error appears: "zfs error: cannot open 'DATA': no such pool".

Please check/share your boot log, journalctl -b > /tmp/boot.log. What is the output of the following

zpool import
zpool status -v
lsblk -o NAME,MAJ:MIN,SIZE,TYPE,FSTYPE

?

Hi Fiona,

Hi Fiona,
omg, I just forgot, that the DATA pool resides on a second sdd with 4TB.
Unfortunately I guess I run into the known firmware bug of samsung's 870 evo SSD, which makes sectors unreadable.
I've tried to update the firmware, but failed here on different devices: the ssd is just (half?) dead.
It can still be recognized, but not read or updated. I also tried two tools, which are able to repair zfs drives, but stopped both after 1000nds of read errors... I will open a ticket by samsung, the drive is one year old.
Thx a lot for your help!
Andreas

Hello.

Is it possible to disable that warning?

I've created a VM to emulate ARM64 hardware, which has no EFI disk (I don't require it and don't want it), and the warning gets pretty annoying over time.

I thought, maybe there's a way to get that warning out of the way... after all it's just a warning, not an error.

Regards!

 

[fiona]

Hi,

Is it possible to disable that warning?

Not without patching the code.

I've created a VM to emulate ARM64 hardware, which has no EFI disk (I don't require it and don't want it), and the warning gets pretty annoying over time.

The VM is using the default read-only EFI disk for ARM64 if you don't create one. It is required to boot for OVMF. But the VM won't be able to persist any EFI-related settings like that. What is the issue with creating one for the VM?
