The starting logical volume (vm) is 1TB. The volume group (data) has plenty of free space. This can be queried with lvdisplay.

The following command will extend the logical volume vm under volume group data by 4 TB

lvextend -L4T /dev/data/vm
resize2fs /dev/data/vm

Run vgdisplay to confirm:

After the logical volume (vm) has been extended to 5TB, there are still more than 20 TB of free space in data volume group.
