I created a new img using the following command:
truncate -s 250G disk.img
and I replace the existing image that I used for zpool with that one using (lxd.img was 2G):
zpool replace lxd lxd.img disk.img
I set the autoexpand to on
sudo zpool set autoexpand=on lxd
But the size is still 2GB and I have an EXPANDSZ property that states the size of the new image.
NAME SIZE ALLOC FREE EXPANDSZ FRAG CAP DEDUP HEALTH ALTROOT
lxd 1.98G 1.82G 170M 248G 69% 91% 1.00x ONLINE -
How can I fix this?
