Error after upgrade to 6.2

[jmazur]

Hi,

Today I updated my single node Proxmox installation from 5.4 to 6.2. Unfortunately after reboot it won’t start. It looks like some grub errors. Proxmox is installed on ZFS. Please find below the photo of errors displayed. How can I recover it?

Hello @jmazur

have you updated the system with this documentation? https://pve.proxmox.com/wiki/Upgrade_from_5.x_to_6.0
On what hardware exactly you have installed your system?
Ist it an bios or EFI installation?
What RaidLevel?

Hi,

Yes I followed the exact link you mention.
The system is my home lab so its i3 4330T with Asus B85M-E mobo.
Its EFI installation with RAID 1 on ZFS.

Unfortunately this system also run router for my home network so I had to act quick and make fresh install of Proxmox 6.2.
Never the less it would be great to know what to do if such situaion happens in the future.
