title: Im trying to add additional space to my virtual machine. I went from 250GB to +750GB but am having trouble adding it to the lvm
body: <p>Current my pv looks like this</p>
  <pre><code>tj@ubuntugis:~$ sudo pvdisplay
    --- Physical volume ---
    PV Name               /dev/sda3

    PV Size               &lt;31.00 GiB / not usable 1.00 MiB
    Allocatable           yes (but full)
    PE Size               4.00 MiB
    Total PE              7935

  <p>So the Physical Volume is the size I expect.
  The vgdisplay looks like there is quite a bit of space unallocated</p>
  <pre><code>tj@ubuntugis:~$  sudo vgdisplay
    --- Volume group ---
    VG Name               ubuntu-vg
    System ID
    Format                lvm2
    Metadata Areas        2
    Metadata Sequence No  7
    VG Access             read/write
    VG Status             resizable
    MAX LV                0
    Cur LV                1
    Open LV               1
    Max PV                0
    Cur PV                2
    Act PV                2
    VG Size               &lt;720.77 GiB

  <p>I think my problem is that I extended an existing physical volume instead of creating a new one.  Is there an easy way to fix this so I can associated the new 489 GB with ubungu-vg</p>
