Answer 1

What about the notification tag? (the toaster called me as an expert on notifications)
If on the topic:
1. If you do not have LVM, then you can’t. It can compress and decompress mounted volumes.
2. As an option ... you can think about how to cleverly drag everything important like a thread into the RAM and change the mount point, but it's time consuming and not the fact that it's releasable.
3. The easiest way is to compress 100 gigs of the rest in a running system, and then increase it after launch.
I googled it..
https://access.redhat.com/documentation/en-US/Red_... it looks like you can. google all this on ext4 resize online, of course all this is available only if you have ext4.
And yes - you can increase the mounted partition, but you can not reduce it.

gparted is here to help.
Cut into a flash drive, boot, cut from the right, add to the left.
