Hello! I installed LEDE on a 2 GB SD card and am running it on Ras Pi 3 B, while it seems that root doesn't make use of all the space. I tried to extend root by extending /dev/mmcblk0p2, or ls -n and resize2fs but root just got a bit larger. How can I extend root to the rest space so that I could be able to install more packages? Thanks!
