Public bug reported:
We were running lxd w/ a zfs (zpool) backing our system. We retired the
service that had been running in lxd (stopping the lxd container) and
the zpool was removed from the computer.
When we tried to upgrade (from bionic to focal), the lxd upgrade failed.
It's true, we effectively shot ourselves in our foot (years ago).
Solution:
1. systemctl stop lxd.service lxd.socket
1. mv /var/lib/lxd /var/lib/lxd.0
1. zfs create tank/lxd
1. zfs get compression tank/lxd # returns lz4
1. lxc storage create pool1 zfs source=tank/lxd
1. systemctl start lxd.service lxd.socket
Expected result:
it'd be nice if there was a vaguely helpful error message -- I used `strace` to
slowly figure out that there were
`/var/lib/lxd/database/global/snapshots/*/state.bin` references to it and there
wasn't any particularly obvious way to do anything to resolve this (renaming
the snapshots directory didn't result in a happy state).
