Reclaims the half-disk LV left by the Ubuntu Server autoinstall template default. Idempotent — no-ops cleanly when there are no free PE in the VG, and exits the play cleanly on hosts without LVM. Supports ext4 and xfs. Does not handle partition resize (cloud-utils growpart) — out of scope for the template fix-up case. Wired into day1_deploy_honcho.yml ahead of the honcho role so newly provisioned VMs get the fix-up automatically. Suitable to add to any day1 playbook by simply listing it before the application role.

# Extends the root LVM logical volume to fill its volume group, then grows

# the underlying filesystem to match. Idempotent: when there's no free PE
|
|
# in the VG (i.e. the LV already fills the VG), the lvextend step is a
|
|
# no-op and resize2fs/xfs_growfs simply confirms the filesystem is at

# reclaim the unallocated PE; safe to leave in a day1 playbook so future

# disk expansions are picked up automatically.
