Yes after the upgrade at 00:06h my containers were still running because I did not shut them down prior to upgrade LXD. Few minutes after 00:13:57h I went to see why it took so long to reboot and gave the system a hard reset.
Perhaps this explains the log?

I started over a year ago with my first container and installed an basic configuration with zfs.
The zfs drive is a separate partition on the host. Nothing special…
I send you the requested tarball.
