The expand command takes an expand point followed by an optional name value pair and an expandable object. To find the expand point, use the query command with the Expand Points filter on the object or volume you plan to expand. For example:
query: expand points, "/dev/evms/lvm/Sample Container/Sample Region"
Use a list options filter on the object of the expand point to determine the name-value pair to use, as follows:
query: objects, object="lvm/Sample Container/Sample Region", list options
The free space in your container is the container name plus /Freespace.
With the option information that is returned, you can construct the command, as follows:
expand: "lvm/Sample Container/Sample Region", add_size=500MB, "lvm/Sample Container/Freespace"
