# Script for importing VDO volumes to lvm2 managed VDO LVs
#
# Needed utilities:
#  lvm, dmsetup,
#  vdo,
#  grep, awk, sed, blockdev, readlink, stat, mkdir, truncate
#
# Conversion is using  'vdo convert' support from VDO manager to move
# existing VDO header by 2M which makes space to place in PV header
# and VG metadata area, and then create VDOPOOL LV and VDO LV in such VG.
