Expanding the Kali Root Partition

Question

I have a live distribution of Kali running on a usb with persistence. However, after installing updates and a few new software packages, the root drive is pretty much out of space.

How do I go about resizing this? I've tried booting GParted on a separate live USB and extending the drive, however GParted puts a little yellow triangle to the left of the /dev/sdb1 partition and essentially locks it.

I have also tried resizing the disk during runtime using resize2fs but to no avail. I have been at this for hours now and I'm at breaking point so if anyone could help me out i'd very much appreciate it.

Below is a copy of my fdisk -l output:

Solution 1

If you need the text mode to resize partitions you can try parted: https://www.centos.org/docs/5/html/5.2/Deployment_Guide/s2-disk-storage-parted-resize-part.html

Solution 2

Have you tried using cfdisk? It's a command line based partition editor, and it's worked for me whenever I needed to do anything involving creating/resizing partitions.

How would one use this?

Is there any graphical tool? and would a CentOS tool work on Kali? Or will i have to download and boot a CentOS distro?

Go to bash, and type 'cfdisk' with superuser privileges (i.e. with 'sudo' or after an 'su' or 'sudo su'). You should see a menu pop up where you can select/alter/resize partition tables. If you've not heard of this command until now, then I feel obligated to point out that reading the man page would be helpful.
