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.
Bypass some sanity checks.

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", ...
Be more verbose.
Answer "yes" at any prompts.
Print verbosely commands without running them.
With this option conversion tool will not use snapshot
(COW storage) for conversion in your $TMPDIR filesystem
and it will directly manipulate with VDO device in-place.
Warning: the snapshot usage makes the whole conversion
transactional and the snapshot can be just simply merged
once the whole conversion has successfully proceeded. In
the case of error the snapshot is just removed. Without
the use of snapshot there is higher risk of problems with
recoverability in case some unexpected error occurs.
Configuration file for VDO manager. Can be used to specify
configuration for vdo manager.
TMPDIR The temporary directory name for mount points. Defaults to
The device directory name. Defaults to "/dev" and must be
an absolute path.
Specify uuid prefix for snapshot volume used during vdo
