Gparted cannot resize extended or LVM partition

After some help from linuxdev2013, this is what I did:
The problem was that the partitions were somehow locked. So:

1. I right Clicked both sda2 and sda5 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]
