As seen, I ran out of space on my root partition. I've taken the following steps, but df still shows it being filled. What have I done wrong? Thanks
EDIT 1. Rebooted the machine, and now I can not putty into it.
EDIT 2. Sorry, I don't know how to add an image to a LinuxQuestions post, however, included a picture of the physical machine monitor
