Example
lvm_import_vdo [/dev/mapper/vdo_volume]
Example
lvm_import_vdo -n [vg_name/lv_name] [/dev/mapper/vdo_volume]
Example
lvm_import_vdo --dry-run [/dev/mapper/vdo_volume]
Example
lvm_import_vdo --no-snapshot [/dev/mapper/vdo_volume]
Verbose output
lvm_import_vdo -v -y [/dev/mapper/vdo_volume]
Example
lvm_import_vdo --vdo-config [path/to/vdo.conf] [/dev/mapper/vdo_volume]
说明
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.
