lvm_import_vdo — utility to import VDO volumes into a new volume
group.
lvm_import_vdo
[options] device
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.
-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.
--dry-run
Print verbosely commands without running them.
--no-snapshot
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.
--vdo-config
Configuration file for VDO manager. Can be used to specify
configuration for vdo manager.
On successful completion, the status code is 0. A status code of
1 is used for failure.
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
TMPDIR The temporary directory name for mount points. Defaults to
"/tmp".
DM_DEV_DIR
The device directory name. Defaults to "/dev" and must be
an absolute path.
DM_UUID_PREFIX
Specify uuid prefix for snapshot volume used during vdo
conversion.
LVM_BINARY
Allow to override command called from lvm. Defaults to
"lvm".
VDO_BINARY
Allow to override command called from vdo. Defaults to
"vdo".
