Extend the Disk Size in Ubuntu 20.04 Which Running in VMware


Ubuntu extend disk is different with CentOS, largely using cloud-guest-utils tools.

apt-get install cloud-guest-utils
parted -l # Usually sda 3 is the root fs
growpart /dev/sda 3
pvs # To get the PV name
pvresize /dev/sda3
df -h # find /dev/mapper/ubuntu--vg-ubuntu--lv or similar
lvextend -r -l +100%FREE /dev/mapper/ubuntu--vg-ubuntu--lv
