What are your problems again, and how did you get there? A reproducer
or step by step would be helpful.
My GUESS is that you somehow tell lxd to use your CURRENT root
partition (e.g /dev/sda1) as a NEW zfs pool. Is that what happened?

lxd can either create a new zfs pool (destroying whatever is currently
on the block device), or an existing zfs dataset (which can be part of
any pool, including root pool). You dont need to use zfs root to use
zfs backing store for lxd, as long as you either have a free block
device (loopback also works for testing purposes), or an existing zfs
dataset.
