After creating a CentOS container in LXD running on CentOS 7.7. We wanted to increase the disk size. We did:
lxc config device override alextest root size=100GB
lxc config device set alextest root size 100GB
And the command “lxc config show – expanded alextest” shows root being 100GB. When we log into the container and do a “df -h” we do not see any change, the filesystems are all the same size as before.
I assume we now need to expand the filesystem inside the container or create a new filesystem using the free space from the 100GB. How do we do that?
