LVM and Mounting

This role will create an LVM from a specified physical disk and and mount it to a specific disk.

This role was originally designed for longhorn but its approach is one of the most reinvented flow in VM's. The Default's values are set for setting up an ext4 LVM and attach it to the default disk space for the longhorn application deployed via Helm v3.

Requirements

• Ansible 2.10+

Tested on

• Rocky Linux 8
• Ubuntu 20.04 LTS
