2020-10-15 Upgrade to Ubuntu 20.04

Overview

AUBURN was upgraded to 20.04. I had to re-install Ansible.

Procedure

Upgrade the O/S

Ran the following commands to upgrade the O/S:

sudo apt -y upgrade
sudo apt --fix-broken install -y
sudo apt -y upgrade
sudo apt -y autoremove

Got the following error messages:

  WARNING: PV /dev/xvda5 in VG auburn-vg is using an old PV header, modify the VG to update.
  WARNING: PV /dev/xvdd in VG auburn-vg is using an old PV header, modify the VG to update.

Fix PV Headers

According to PV is using old PV header, the solution to having an old PV header is:

vgck --updatemetadata vg02

Ran the following command to update the PV header:

sudo vgck --updatemetadata auburn-vg

The output is:

  WARNING: PV /dev/xvda5 in VG auburn-vg is using an old PV header, modify the VG to update.
  WARNING: PV /dev/xvdd in VG auburn-vg is using an old PV header, modify the VG to update.
  WARNING: updating PV header on /dev/xvda5 for VG auburn-vg.
  WARNING: updating PV header on /dev/xvdd for VG auburn-vg.

Ran the following command to display the current status of the volume group:

sudo vgdisplay auburn-vg
