lvm_import_vdo

Convert a standalone VDO volume into an LVM-managed VDO logical volume

TLDR

Rehearse the conversion first, since the real thing cannot be undone

$ lvm_import_vdo --dry-run [/dev/mapper/vdo_volume]

Convert a VDO volume, letting LVM choose the names

$ lvm_import_vdo [/dev/mapper/vdo_volume]

Choose the volume group and logical volume name yourself

$ lvm_import_vdo --name [vg_name/lv_name] [/dev/mapper/vdo_volume]

Answer the prompts automatically and show each step

$ lvm_import_vdo --verbose --yes [/dev/mapper/vdo_volume]

Skip the protective snapshot, which is quicker but leaves no way back

$ lvm_import_vdo --no-snapshot [/dev/mapper/vdo_volume]

Read the settings from a VDO manager configuration file

$ lvm_import_vdo --vdo-config [path/to/vdo.conf] [/dev/mapper/vdo_volume]

lvm_import_vdo converts a VDO (Virtual Data Optimizer) volume created with the standalone VDO manager into an LVM-managed VDO logical volume. This allows integration with LVM's volume management capabilities while preserving the VDO deduplication and compression features.The conversion is irreversible and migrates the VDO metadata format. By default, a temporary snapshot is created for safety during the conversion process.VDO provides inline deduplication and compression for block storage, reducing storage requirements for workloads with redundant data like virtual machines and containers.

PARAMETERS

-n, --name _vg/lv_

Specify the destination volume group and logical volume name

--dry-run

Preview the import without making changes

--no-snapshot

Skip creating a temporary snapshot during conversion (faster but riskier)

-v, --verbose

Enable verbose output

-y, --yes

Automatically answer yes to all prompts

--vdo-config _file_

Use a VDO manager configuration file during import

INSTALL

sudo apk add lvm2-extra

CAVEATS

This operation is irreversible; the original VDO volume format cannot be restored. The --no-snapshot option skips safety mechanisms and should only be used when snapshot creation fails. Back up important data before importing. Requires root privileges.
