I wish to increase the disk space of my Ubuntu OS (ext4) drive from 70 GB by around 200 GB. Now , I followed the steps on this link and successfully decreased the partition for my D drive from 292 GB to 54 GB. So it created an unallocated space for 241 GB as shown in the screen-shot.
Now, I wish to increase the disk space of my Ubuntu drive(ext4) from 69GB till as much as I can consume from the unallocated space.
When I right click on ext4 -> Go TO Resize -> It shows me below screen. It does not shows an option to increase the disk space. I can only SHRINK it. However, I wish to grow this space. Can anyone tell me where am I going wrong ? TIA :)
