I created a VM using VirtualBox and realized it was too small. After some time I managed to create a new, bigger hard drive.

Live GParted CD image (v.022):

GParted screenshot

Now I need to integrate the unallocated space to the /dev/sda5 partition.

  • Right-clicking on sda5 shows the option to resize but I dont get any free space before or after.
  • I though that perhaps I needed to extend the sda2 partition first but right-clicking on sda2 does not allow me to resize.

Do you have any useful advice?

this image sourced from the linux HOST or GUEST (aka VM) – linuxdev2013 May 22 '15 at 0:33
    
The image is from the guest VM, sorry if I was not clear – papnikol May 22 '15 at 0:38

Okay , Is the vg crypted OR just mounted in both cases it needs to be unmounted and additionally in the first case decrypted and unmounted – linuxdev2013 May 22 '15 at 0:40
    
It is not encrypted. Since I started from the gparted live cd, shouldn't all partitions be unmounted? If not, how do I unmount them from gparted? – papnikol May 22 '15 at 1:06

the lock implies mounted or crypted select them should have ` unmount ` option – linuxdev2013 May 22 '15 at 1:56

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 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]

Thanks! I also needed lvm lvdisplay to get the exact device for lvextend, and later df -h to find out the volume on which to resize. – Andreas Reiff Aug 20 '15 at 11:02
    
Thanks for your precise answer, that saved me hours and grey hair! – derFunk Sep 2 '15 at 16:40
    
After using gparted, the partition wasn't showing the right amount free. These 2 command line functions were exactly what I needed to finish the job. Thanks for sharing that wizardry – twig Nov 25 '15 at 22:54
    
Unfortunately, for me deactivating them doesn't work. No error message either... Any hints? – Christoph Wurm Dec 4 '15 at 16:08

I had to run sudo lvdisplay to get the [MOUNTPOINT]. In my case it came back as LV Path (/dev/ubuntu-vg/root) – Sheamus O'Halloran Mar 9 '16 at 21:10
