earth!
Hi All,

I did receive the message in the topic today after applying the latest updates when running

Code:
proxmox-boot-tool status

Re-executing '/usr/sbin/proxmox-boot-tool' in new private mount namespace..
E: /etc/kernel/proxmox-boot-uuids does not exist.

When I run proxmox-boot-tool refresh I get...

Code:
# proxmox-boot-tool refresh
Running hook script 'proxmox-auto-removal'..
Running hook script 'zz-proxmox-boot'..
Re-executing '/etc/kernel/postinst.d/zz-proxmox-boot' in new private mount namespace..
No /etc/kernel/proxmox-boot-uuids found, skipping ESP sync.

... any idea?

On another system I got:
Code:
Configuring grub-pc
-------------------

GRUB failed to install to the following devices:

/dev/sda /dev/sdb

Do you want to continue anyway? If you do, your computer may not start up
properly.

... any idea?
the output usually just indicates that you're not using proxmox-boot-tool to boot your system - this usually means:
* you either are not using ZFS on '/'
* you setup the system before PVE 6.4 and are booting from zfs directly from grub
** this is explained in the wiki-page:
https://pve.proxmox.com/wiki/ZFS:_Switch_Legacy-Boot_to_Proxmox_Boot_Tool

in any case - on what filesystem is your '/' and do you have any issues apart from these warning messages on that system?

On another system I got:
Code:

GRUB failed to install to the following devices:

/dev/sda /dev/sdb

Do you want to continue anyway? If you do, your computer may not start up
properly.

Writing GRUB to boot device failed - continue? [yes/no]
that seem quite unrelated to me - please post more of the logs/terminal output that lead to that issue
 
Hi,

I am using zfs on that system:
Code:
# zpool list
NAME    SIZE  ALLOC   FREE  CKPOINT  EXPANDSZ   FRAG    CAP  DEDUP    HEALTH  ALTROOT
rpool   232G  9.92G   222G        -         -     8%     4%  1.00x    ONLINE  -

The error (grub-pc) was showing up when I did an apt-get dist-upgrade

Tobias
 
Then I assume you setup this system sometime before PVE 6.4 (where proxmox-boot-tool support for legacy booted systems was introduced)
How to migrate to proxmox-boot-tool (in case you want to upgrade your pool - but also as a general recommendation) is explained in the wiki-article I linked

I hope this helps!

Hi,

That might be... will probably re-set-up those servers sometime soon.

Tobias
 
any chance you still have the terminal output from the system where grub-install failed? (there might be an issue with proxmox-boot-tool)
 
I sent a patch for the issue I managed to reproduce:
https://lists.proxmox.com/pipermail/pve-devel/2022-September/053894.html

as a mitigation - you can apply it or - run `grub-install.real /dev/sda; grub-install.real /dev/sdb`

Unfortunatly: no, sorry.
If you could also check /var/log/apt/term.log (and rotated variant) it would be great! (just so that we do not overlook another issue) - thanks!

for completeness sake - another thread in our forum is also discussing this issue:
https://forum.proxmox.com/threads/proxmox-update-from-7-2-4-grub-update-failure.114951/

thank you for the information.
I also ran into the same issue and I rebooted my system. It's stuck at grub rescue .. can't get anything out of ls and the drives or partitions.
I also tried a bootable USB device with 7.1 and 7.2 and the rescue mode and it get's the error:


Code:
error: no
such device: rpool.
ERROR:
unable to find boot disk automatically.

any help on this one?

thank you for the information.
I also ran into the same issue and I rebooted my system. It's stuck at grub rescue .. can't get anything out of ls and the drives or partitions.
I also tried a bootable USB device with 7.1 and 7.2 and the rescue mode and it get's the error:
that should not happen due to the failing grub-install ...
in any case the section in the linked wiki-page might help in that case:
https://pve.proxmox.com/wiki/ZFS:_S...iring_a_System_Stuck_in_the_GRUB_Rescue_Shell

make sure to create a backup of everything on the system!
 
Thank you!
I tried the solution and when I try:

zpool import -f -R /mnt rpool

within the debugg mode I get the error:

cannot import 'rpool': no such pool available
this sounds odd - is your system using zfs on / at all? - I currently doubt that what you're seeing is related to the issue of this thread - and would suggest to open a new thread for it (feel free to notify me with @Stoiko Ivanov so that I don't overlook the thread)
if you open the thread please post (if not possible as plain-text then as screenshots):
* `lsblk`
* `zpool import`
* the grub-screen you're seeing when trying to boot
