I have ubuntu running to 447G ssd. However for some reason ubuntu only took 100G of that space on install (maybe I have missed something, does not matter now). How can I extend this partition to use all available space (preferably without data loss). Here is lsblk output:

as you can see └─ubuntu--vg-ubuntu--lv only takes 100G, instead of 444 available.
