lvm_import_vdo

Import a VDO volume with automatic names for the VG/LV

$ lvm_import_vdo [/dev/mapper/vdo_volume]

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

lvm_import_vdo [options] device

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.

-n, --name _vg/lv_

Specify the destination volume group and logical volume name

Preview the import without making changes

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

Enable verbose output

Automatically answer yes to all prompts

Use a VDO manager configuration file during import

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.
