Supported Platforms

Any Linux distribution with LVM support, including:

Platform	Versions
Ubuntu	20.04, 22.04, 24.04
Debian	11, 12
Rocky Linux / RHEL	8, 9
Fedora	39+

Requirements

Unpartitioned disk devices to assign to volume groups
lvm2 package (installed automatically by the role)

Important: Safety Default

manage_lvm defaults to false. The role will not make any disk changes unless you explicitly set:

manage_lvm: true

This prevents accidental modifications on misconfigured runs.
