Accidentally removed lxd (zfs storage backend)

[Norberto Bensa]

Hello list!

I ran apt autoremove snapd, which -I thought- was an "empty" package, but the command removed snapd and every snap package, lxd included :-)

My storage backend is ZFS, and I can see my containers are still there:

zpool/lxd/containers/container-name

I can mount and backup them (I already did), but I would like to see if I can rerun lxd init and recover the installation.

If I run lxd init, I get the following error: Error: Failed to create storage pool "default": Provided ZFS pool (or dataset) isn't empty

$ lxd init

Would you like to use LXD clustering? (yes/no) [default=no]:

Would you like LXD to NAT IPv4 traffic on your bridge? [default=yes]:  
What IPv6 address should be used? (CIDR subnet notation, “auto” or “none”) [default=auto]:  
Would you like the LXD server to be available over the network? (yes/no) [default=no]:  
Would you like stale cached images to be updated automatically? (yes/no) [default=yes]:  
Would you like a YAML "lxd init" preseed to be printed? (yes/no) [default=no]: no
Error: Failed to create storage pool "default": Provided ZFS pool (or dataset) isn't empty

I also tried `zfs rename zpool/lxd zpool/lxd-backup`, then `lxd init`, `snap stop lxd`, rename the new zpool/lxd to somehing else, rename lxd-backup to lxd, `snap start lxd`, but lxd doesn't see the containers.

Any help would be appreciated!

Thank you!
