    pvs: /dev/sda1
    pesize: 32

# Create or resize a volume group on top of /dev/sdb1 and /dev/sdc5.
# 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.
