Zfs pool is automatically converted to dir pool after upgrading to Ubuntu 21.10

Is it done on purpose?

After a search around I found some information states that zfs is broken on 21.10

Hmm, when upgrading from what?

The LXD snap package is the exact same on 21.04 and 21.10 so no upgrade actually occurs, LXD also has no way to convert from ZFS over to dir so I’m quite confused by what you’re describing :slight_smile:
