LAN connection problem (deja vu) in Linux Posted September 6, 2016 · Edited September 6, 2016 by terry1966 · Report reply sorry been so long in getting back to you kurt, but after spending hrs trying different ways to resize a root partition and being able to log back in again after, i think you'll be better off just doing a clean install but with a bigger root partition to start with. anyway to cut a very very long story short, it is possible but it's also very convoluted. i finally succeeded by first logging in as root in run level 3, umount /home, resize it to minimum or size you want to add to root, create a new partition in empty space, dd /home across to new partition, mount new partition as home, delete old home. then reboot to a live cd so i could finally resize the root partition to use the free space left from when i deleted the old home partition. that was the only way i found i could resize things and still be able to boot into the desktop again after, don't know what the problem was doing things any other way but first i thought it might be a uuid issue in fstab but mounting partitions by label never fixed it, so i assume it must have been a permission issue copying the user folder back caused (even though i did try and set the folders permissions back to username and user group) any whatever the issues were i think using dd fixed that problem. upto you but if you want to try it anyway instead of doing a clean install i'll give detailed instructions on how i did it, but i can't guarantee they'll work for you even though i don't see why not. thinking about it, i don't think i tried dd when i just used a live cd to do everything, so might give that a try in a bit which if it works should make things a bit easier than the way i finally did it.
