Grow logical volume

Grow logical volume

Sometimes I had been the scenario where I needed to extend the logical volume of my system such as:

  • A VM which required more space and after increase the available disk I had to extend the logical volume.
  • A raspy using not the usual distros.

The same steps worked for me in a fedora system. I won't extend and I will go straight to the point.

In this steps I am using /dev/sda3 update it for your scenario:

  • Increase the physical partition: fdisk /dev/sda3
  • Increase the physical volume: pvresize /dev/sda3
  • Increase logical volume: /dev/mapper/systemVG-LVRoot -L+100%FREE
  • Grow filesystem: xfs_growfs /dev/mapper/systemVG-LVRoot

Hope this helps you in similar scenario, take the above steps at your own risk and create a backup before run them if you are not sure what your are running. Be warned that something wrong could state in a broken system.

See you on the next post!
