@ -368,18 +368,28 @@ Logical Volume Manager (LVM) physical volumes, volume groups, and logical
volumes may be configured via the ``lvm_groups`` variable. For convenience,
this is mapped to the following variables:
* ``seed_hypervisor_lvm_groups``
* ``seed_lvm_groups``
* ``compute_lvm_groups``
* ``controller_lvm_groups``
* ``monitoring_lvm_groups``
* ``storage_lvm_groups``
Note that LVM is not configured on the seed hypervisor.
The format of these variables is as defined by the ``lvm_groups`` variable of
the `mrlesmithjr.manage-lvm
<https://galaxy.ansible.com/mrlesmithjr/manage-lvm>`__ Ansible role.
LVM for libvirt
---------------
LVM is not configured by default on the seed hypervisor. It is possible to
configure LVM to provide storage for a ``libvirt`` storage pool, typically
mounted at ``/var/lib/libvirt/images``.
To use this configuration, set the ``seed_hypervisor_lvm_groups`` variable to
``"{{ seed_hypervisor_lvm_groups_with_data }}"`` and provide a list of disks
via the ``seed_hypervisor_lvm_group_data_disks`` variable.
