Updating Kernel to 6.8.12-3 results in failed startup

[andrzej.strupiechowski]

Hi, i'm getting an error after upgrading to kernel 6.8.12-3:
/dev/mapper/pve-root does not exist
I was able to fix it with pve-efiboot-tool kernel pin 6.8.12-1-pve, using 6.8.12-2-pve also returned the same error. How can i remove troubled kernel?
apt purge proxmox-kernel-6.8.12-3-pve-signed returns the following:

Do you want to continue? [Y/n] y

W: (pve-apt-hook) !! WARNING !!

W: (pve-apt-hook) You are attempting to remove the meta-package 'proxmox-ve'!

W: (pve-apt-hook)

W: (pve-apt-hook) If you really want to permanently remove 'proxmox-ve' from your system, run the following command

W: (pve-apt-hook) touch '/please-remove-proxmox-ve'

W: (pve-apt-hook) run apt purge proxmox-ve to remove the meta-package

W: (pve-apt-hook) and repeat your apt invocation.

W: (pve-apt-hook)

W: (pve-apt-hook) If you are unsure why 'proxmox-ve' would be removed, please verify

W: (pve-apt-hook) - that you are using 'apt full-upgrade' to upgrade your system

Is it safe to do?

you can't remove the default kernel's current version (but you also don't need to, if you temporarily pin an older one). the question is why the -3 one doesn't work..

 

[andrzej.strupiechowski]

Adding root delay and forcing initramfs also didn't help. Are there other obvious reasons for root drive being invisible?

 

[fabian]

what kind of disk(s) are underneath your LVM? do you get dropped into an initrd debug shell?

 

[andrzej.strupiechowski]

My boot drive is PNY CS2130 500GB, I did get dropped to initramfs

 

[fabian]

can you check whether the disk itself shows up there (`lsblk` or `ls /dev/`)? you could also dump dmesg and see if anything interesting is showing up there..

 

[andrzej.strupiechowski]

There is no disk under lsblk or /dev/

 

[fabian]

and the dmesg output?

 

[andrzej.strupiechowski]

I'm sorry for a stupid question but are you asking about my dmesg output from pinned working kernel or from initramfs?

 

[fabian]

from initramfs - but the initial dmesg of the working boot might be interesting to compare against as well..

 

[andrzej.strupiechowski]

There are no errors, it just doesn't see internal nvme, only USB drive which stores my backups, -4 kernel bajeves the same way

 

[fabian]

could you still provide the dmesg output?
