I am new to ubuntu server and still pretty mystified by all the scripts and such. I have been reading different things available on the web and have successfully created my server and have several folders that I am able to write to using my windows computers. The problem is, when I was following one of the tutorials to start, I created a partition of 20gb to use for the OS. I have a 2tb disk and now I am out of space, even though I have another 1.8tb available. I used the lvm option when I loaded the system and was lead to believe I could expand the partition easily. The problem is, I don't know how and I can't seem to find an example that seems to fit my situation. Any help would be greatly appreciated.
I am using ubuntu server 14.04
