[PVE-User] ZFS Node failing to boot

[Lindsay Mathieson]

I have a 4.x Proxmox node that is failing to boot today, get past the 
bios etc, then blank screen with a blinking cursor - no console output 
from the boot process at all.

- vs 4 + latest updates from no-sub repo

- Have explicitly picked the boot drive at start to ensure it using the 
right disk

- Boot disk is a 240MB Kingston SSD (no raid)


Fortunately I was about to boot the system using the rescue mode from 
the Proxmox ISO, and it running fine now, but still won't boot without 
the rescue iso. But I can access the disks and they seem ok.


I presume its some sort of grub error but I have no idea how to repair a 
zfs boot drive.
