How to resize your linux partition when you have this problem (see image)?

Long time since my last blog update, so here goes :D

IMPORTANT NOTE: before doing step 1-3, you need to insert a Ubuntu live-cd and boot from it. And then, open gparted in the live-cd and continue with step 1-3.

The problem was that the partitions were somehow locked. So:

1. I right Clicked both sd2 and sd5 and chose "Deactivate".
2. I resized the extended (sda2) partition.
3. I resized the lvm (sda5) partition.

The problem was fixed
I should add that in the VM the new space was not available, so I had to run those 2 commands: expand LVM to all remaining free space:

lvextend –l +100%FREE [MOUNTPOINT]

expand filesystem:

sudo resize2fs [MOUNTPOINT]

::NOTES::

1. To display Mountpoint run the command lvdisplay to display where is 

the root directory. For example, /dev/nameoftheserver/root

2. After that, run lvextend -1 +100%FREE /dev/nameoftheserver/root

3. Run sudo resize2fs /dev/nameoftheserver/root.
