I am new to ubuntu and a little confused about how hard drive partitions and LVM works. I remember setting up Ubuntu server 13.04 and telling to to use 1TB of a 3TB server. Well I have maxed that out with blu-ray rips and want the rest of the drive for space.

On log-in it says:

  System load:  2.24                Processes:           179
  Usage of /:   88.7% of 912.89GB   Users logged in:     0
  Memory usage: 6%                  IP address for p5p1: 192.168.0.100
  Swap usage:   0%

  => / is using 88.7% of 912.89GB

And fdisk /dev/sda -l outputs:

Partition 1 does not start on physical sector boundary.

I just don't know what to make of all this and am not sure how I can make it use all 2.73TBs.

Thanks in advance for any help.

EDIT--

Yes I did make changes to the LVM Config, but it didnt do anything.

As requested, output of parted -l /dev/sda
