Ubuntu 14.04 Extend logical or physical disk space​

This worked for me when I needed to extend the disk space in a vmware virtual machine. Once you extend the space in vCenter you need to reboot the VM.

Create a partition with available disk space using this command.



Select available space then choose ‘write’ then ‘quit’.


Scan for the new partition with:

partprobe /dev/sda

You may need to restart if the above command doesn’t work.

Check for the new partition with:

fdisk -l /dev/sda


Create a new volume (I will assumed the new partition found above is sda3)

pvcreate /dev/sda3


Show the physical volumes with



Now we can extend the primary disk with the following commands. You should be able to get the VOLUME_GROUP name from the above command.

vgextend VOLUME_GROUP /dev/sda3

lvextend -l+100%FREE /dev/VOLUME_GROUP/root

resize2fs /dev/mapper/VOLUME_GROUP-root


Check available space with:

df -h
