This question already has an answer here:
How to extend my root (/) partition?
2 answers
I need more space on my root partition running Ubuntu 17 (using Xfce session).
I do have a lot of unallocated space BEFORE.
However, when I try to resize root partition - /dev/sdb2
, I can't add/remove a MiB...
Is this even possible?
If so, can it somehow be done from the live system or do I have to use live CD/USB?
There is really just Ubuntu and Xcfe session, LUBUNTU_SYSTEM is just an old label :)

You cannot resize a mounted partition so you have to use a live session. Then you can first move your / partition to the beginning of your disk and then resize. I would recommend a backup before any operation on the partitions - one never knows ...

@muclux will the system and booting remain untouched? :)

Well, as I said, better backup before. But normally all should go well, if you pay attention at what you are doing. Boot from Live DVD/USB, call gparted, move /dev/sdb2 to create an unallocated space behind it, and then resize /dev/sdb2. Don't mount your disk partitions during this operation.

@muclux Thank you, booting a linux live USB (Lubuntu Try Mode) and using GParted worked :) ... I think that I have read somewhere that in newer versions you can resize/move even when in the live system - is it impossible in this case because it is not just expanding to the right but also moving to the left?

You can only grow to the right while it is mounted. Moving requires it to be unmounted. BTRFS can even shrink while it is mounted ;)

A partition can only be resized by modifying its end. Therefore first, you have to move the /
partition to the beginning of the drive, gaining some free space after the moved /
partition. Then you can grow the /
partition which will be done by changing its end block number to a bigger number.
These actions can both be made through GParted, called from a live system on an USB or a DVD, but not from the current system where the partition is currently mounted.
