I've been following this guide https://discourse.ubuntu.com/t/ubuntu-high-availability-corosync-pacemaker-shared-disk-environments/14874
In order to setup the ability for Azure Ubuntu VM's to use a Shared Disk.. I've got to the part to try and mount the gfs2 filesystem I've just created but when I do it says
"unknown filesystem type 'gfs2'
I have installed gfs2-utils, and when I run modprobe it states
"Module gfs2 not found in directory /lib/modules/5.8.0-1033-azure"
These are Azure Ubuntu VM's running 20.04.
