.SH DESCRIPTION
|
|
.
|
|
lvm_import_vdo utility imports VDO volumes created and managed by
|
|
.BR vdo (8)
|
|
manager into
|
|
.BR 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
|
|
.BR lvm2 (8)
|
|
commands,
|
|
.BR vdo (8)
|
|
manager no longer control such volume.
