To resize your lxc containers, you have to resize the pool in which they live.

First stop all your containers:

sudo lxc stop --all

Find the name of the profile your containers are using:

sudo lxc profile list

After getting a list choose the name of the pool your containers are in:

lxc profile show <profile name // usually called "default">

Look at the current storage:

lxc storage info <pool name // usually called "my pool">

Now edit the file containing the storage size:

lxc storage edit <pool name>

Now edit the file containing the storage size:

config:
  size: 50GB
  source: /var/snap/lxd/common/lxd/disks/mypool.img
  zfs.pool_name: mypool
description: ""
name: mypool

Check the new storage:

lxc storage info <pool name>

Check lxc container storage

lxc exec <container name> -- sudo -i
df -h
