vgmerge [-A|--autobackup {y|n}] [--commandprofile ProfileName] [-d|--debug] [-h|-?|--help] [-l|--list] [-t|--test] [-v|--verbose] DestinationVolumeGroupName SourceVolumeGroupName

vgmerge merges two existing volume groups. The inactive SourceVolumeGroupName will be merged into the DestinationVolumeGroupName if physical extent sizes are equal and physical and logical volume summaries of both volume groups fit into DestinationVolumeGroupName's limits.

See lvm(8) for common options.

-l, --list

Display merged DestinationVolumeGroupName like vgdisplay -v.

-t, --test

Do a test run WITHOUT making any real changes.

Merge the inactive volume group named "my_vg" into the active or inactive volume group named "databases" giving verbose runtime information:

vgmerge -v databases my_vg
