Growing a loop backed ZFS pool 

LXD doesn’t let you directly grow a loop backed ZFS pool, but you can do so with:

sudo truncate -s +5G /var/snap/lxd/common/lxd/disks/default.img

sudo zpool set autoexpand=on default

sudo zpool online -e lxd /var/snap/lxd/common/lxd/disks/default.img

sudo zpool set autoexpand=off default
