I understand this has been resolved in the past over here [SOLVED]Error: ZFS storage pool "default" could not be imported: cannot import 'default': no such pool available and the solution did work for me but with differences,
- This was experienced on Ubuntu 19.10 (on a desktop)
- Using Snap (3.18) not .deb
- I can reproduce this issue on my system at-least. It seems like creating default pool in
lxd init
doesn’t work (after rebooting machine) and as long as I createdefault
pool manually correctly things work correctly.
Also, I am pointing it out here because I lost all containers in this case (thankfully I had backups - still restoring) and the fact that I use LXD heavily in production. Not so sure if snap update botched up or there’s something about ubuntu 19.10 that LXD didn’t like or something else but it’d be great if devs can further look into this. I will be happy to provide more details about my system (if need be).
Here’s the output of lxd --debug --group lxd
(with failed lxd service)
