This article demonstrates how to extent a LUKS encrypted volume. We’re using Ubuntu 22.04 and the volume is non-root. Although you could probably do the same on the root volume (partition). This is risky and you should not do this without a backup and understanding the likelihood of failure. ThisRead more
