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.

Check for the new partition with:   Create a new volume (I will assumed the new partition found above is 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.   Check available space with:

The follow process has been tested on Ubuntu versions 18.04 and 20.04 but may also work on newer versions. Run the following command to determine the new path assigned to your new disk:   This should produce an output similar to this:   logical name: /dev/sda      size: 60GiB  logical name: /dev/sdb      size: 100GiB I’ll be partitioning /dev/sdb and using the full available space. Start parted as follows:   Create a new GPT disklabel:   Set the default unit to GB or TB (i’ll be using GB as it’s only 100GB):   Create one partition occupying all the space:   Verify with:   Quit “parted”:   Format the new partition (use one of these commands to format to fat32 or ext4):
