Examples

- name: Create a volume group on top of /dev/sda1 with physical extent size = 32MB
  lvg:
    vg: vg.services
    pvs: /dev/sda1
    pesize: 32

- name: Create a volume group on top of /dev/sdb with physical extent size = 128KiB
  lvg:
    vg: vg.services
    pvs: /dev/sdb
    pesize: 128K

# If, for example, we already have VG vg.services on top of /dev/sdb1,
# this VG will be extended by /dev/sdc5.  Or if vg.services was created on
# top of /dev/sda5, we first extend it with /dev/sdb1 and /dev/sdc5,
# and then reduce by /dev/sda5.
- name: Create or resize a volume group on top of /dev/sdb1 and /dev/sdc5.
  lvg:
    vg: vg.services
    pvs: /dev/sdb1,/dev/sdc5

- name: Remove a volume group with name vg.services
  lvg:
    vg: vg.services
    state: absent
