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?

    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

    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?

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]

    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.

  • 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

  • Unfortunately, for me deactivating them doesn't work. No error message either... Any hints?

    I had to run sudo lvdisplay to get the [MOUNTPOINT]. In my case it came back as LV Path (/dev/ubuntu-vg/root)

appliance@zabbix:~$ sudo lvdisplay

--- Logical volume ---

LV Path /dev/zabbix-vg/root

LV Name root

VG Name zabbix-vg

LV Size 15.52 GiB


--- Logical volume ---

LV Path /dev/zabbix-vg/swap_1

LV Name swap_1

VG Name zabbix-vg

LV Size 4.00 GiB


appliance@zabbix:~$ sudo vgs

VG #PV #LV #SN Attr VSize VFree

zabbix-vg 1 2 0 wz--n- 24.52g 5.00g


As you see i have 5 GB Free space


appliance@zabbix:~$ sudo lvextend -L+5G /dev/zabbix-vg/root

Size of logical volume zabbix-vg/root changed from 15.52 GiB (3973 extents) to 20.52 GiB (5253 extents).

Logical volume root successfully resized.


appliance@zabbix:~$ sudo resize2fs /dev/zabbix-vg/root

The filesystem on /dev/zabbix-vg/root is now 5379072 (4k) blocks long.


appliance@zabbix:~$ sudo lvdisplay

--- Logical volume ---

LV Path /dev/zabbix-vg/root

LV Name root

VG Name zabbix-vg

LV Size 20.52 GiB


--- Logical volume ---

LV Path /dev/zabbix-vg/swap_1

LV Name swap_1

VG Name zabbix-vg

LV Size 4.00 GiB

    He was asking how to resize the physical volume ( the disk partition ), not a logical volume.
