NAME         top

       lvm_import_vdo — utility to import VDO volumes into a new volume
       group.

SYNOPSIS         top

       lvm_import_vdo
              [options] device

DESCRIPTION         top

       lvm_import_vdo utility imports VDO volumes created and managed by
       vdo(8) manager into lvm2(8) managed VDO LV. This is realized by
       moving VDO superblock by 2MiB and creating lvm2 metadata at the
       front of this device. The operation is not reversible, thus after
       conversion to lvm2 the access to VDO data is only possible with
       lvm2(8) commands, vdo(8) manager no longer control such volume.

OPTIONS         top

       -f|--force
              Bypass some sanity checks.

       -h|--help
              Display the help text.

       -n|--name
              Specifies the name of converted VDO LV. When the name is
              not specified, some automatic name is selected. In case
              the converted VDO volume is already using LV a backend
              device, the name of this LV is used for VDO LV.  In this
              case also the of volume group must stay same.  Automatic
              name may change between releases and currently selects
              "vdolv" as LV name and VG name is selected from sequence
              "vdovg", "vdovg1", ...

       -v|--verbose
              Be more verbose.

       -y|--yes
              Answer "yes" at any prompts.

       On successful completion, the status code is 0.  A status code of
       1 is used for failure.

EXAMPLES         top

       Convert VDO volume created by vdo manager into logical volume LV1
       with within volume group VG1.

       # lvm_import_vdo --name VG1/LV1 /dev/mapper/vdo-volume

ENVIRONMENT VARIABLES         top

       TMPDIR The temporary directory name for mount points. Defaults to
