upgrade from 20.04 to 22.04 failed

[Scott Ribe]

do-release-upgrade seems to have failed on grub-efi, wondering if it choked on my config; attached logs as per error message.

System was left in bootable, runnable state, but a zpool was blown away.

------
system pools and one pool on NVMe were ok:

sribe@sribe000:~$ sudo zpool status

but an archive pool on HDD is fubar:

sribe@sribe000:~$ sudo zpool import
   pool: zp_repo
     id: 11719108999789418570
  state: FAULTED
 status: The pool metadata is corrupted.
 action: The pool cannot be imported due to damaged devices or data.
 The pool may be active on another system, but can be imported using
 the '-f' flag.
   see: http://zfsonlinux.org/msg/ZFS-8000-72
 config:

 zp_repo FAULTED corrupted data
 logs
   mirror-1 ONLINE
     nvme-INTEL_SSDPELKX010T8_PHLJ0081015R1P0I-part2 ONLINE
     nvme-INTEL_SSDPELKX010T8_PHLJ008100M71P0I-part2 ONLINE

------
the pool is not active on another system and import with -f fails

Fortunately, reverting to a snapshot of the system before the failed upgrade brought the zpool back. I have a pretty customized ZFS setup, including tweaks to /usr/share/initramfs-tools/scripts/zfs--so it might be the case that I will never be able to use the automatic upgrade.
