proxmox-kernel-6.5.11-3-pve Problems

After installing this kernel all networking is down. All of my interfaces were changed to eth0 - eth7. After messing around with it i got the network to work by changing the network interfaces through my ipmi. I didnt like this so i changed everything back and rebooted into the previous kernel 6.5.11-2-pve and everything was back to working right. I used proxmox-boot-tool kernel pin to select this kernel as default for now. I tried to remove the new kernel with apt but when doing so it insists on removing stuff like proxmox-ve and others. Luckily it threw an error and would not let me do it. I would love some help with this. My machine is a dell r630 and dell r730. Is this a know issue and how do i resolve it?
 
i do get this error when trying to reinstall proxmox-kernel-6.5.11-3-pve
/usr/sbin/grub-probe: error: compression algorithm inherit not supported

No idea if this has anything to do with it i get the error on both nodes
 
I ran zpool status and zpool upgrade and upgraded zpool. Still having issues when booting new kernel. all network interfaces are still messed up. Now i get a new grub-probe error

/usr/sbin/grub-probe: error: unknown filesystem.

Looks like GRUB does not recognize a ZFS feature, which is not uncommon. What is strange is that is does OS probing, which I though it was disabled by default on Proxmox.

Do you need other operating systems in the GRUB menu? Otherwise consider adding GRUB_DISABLE_OS_PROBER=true. I think the prober issues are just warnings and not errors, and not related to the network device renaming issues you are having.

Thank you. I will add this and try. In the main post for 6.5 update others are having this issue as well
 
Just for the record, if anybody finds this post in the (near) future, this is fixed and got more closely discussed in the 6.5 announcement thread:
https://forum.proxmox.com/threads/o...8-available-on-test.135635/page-7#post-606230
This is sadly not fixed. With today's update "proxmox-kernel-6.5.11-6-pve-signed" the issue still persist: "/usr/sbin/grub-probe: error: compression algorithm inherit not supported"

Code:
...

run-parts: executing /etc/kernel/postinst.d/zz-update-grub 6.5.11-6-pve /boot/vmlinuz-6.5.11-6-pve

Sorry I referred to initial post of this thread, not the completely unrelated grub error from the second post…

Are you booting from ZFS and is this an older installation (installed with an ISO before Proxmox VE 6.4)? As we switched booting from a FAT partition for not only UEFI (where it's mandatory) but also legacy BIOS boot to avoid any issues with grub's limited support for some ZFS features.
If that's the case then you might want to follow https://pve.proxmox.com/wiki/ZFS:_Switch_Legacy-Boot_to_Proxmox_Boot_Tool to get rid of this and other such issues once and for all.

Otherwise we'd need more info about your setup, especially the boot and filesystem one.
 
Ah sorry then.

I think I'm already on UEFI with proxmox-boot-tool:

Code:
root@Proxmox:~# proxmox-boot-tool status
Re-executing '/usr/sbin/proxmox-boot-tool' in new private mount namespace..
System currently booted with uefi
DCD8-7B59 is configured with: uefi (versions: 6.2.16-19-pve, 6.5.11-4-pve, 6.5.11-5-pve, 6.5.11-6-pve)
DCDA-7CDC is configured with: uefi (versions: 6.2.16-19-pve, 6.5.11-4-pve, 6.5.11-5-pve, 6.5.11-6-pve)
root@Proxmox:~#

I'll reboot on weekend and see if anything breaks.

Edit: Just rebooted, everything seems fine.
