      Not completely correct statement.
      Until Vsphere 4. You could only increase a datastore by adding extents.

      From Vsphere 4 and up GROWING an EXISTING EXTENT is possible.

    VMFS Datastores in vSphere 4.x and 5.x can be increased in size by adding a new extent on a DIFFERENT storage DEVICE (spanning), or by increasing the size of the EXISTING storage DEVICE and then GROWING the existing datastore extent to fill that available adjacent capacity.

    So in this case the EXISTING extent can GROW.
    NOTE: Each LUN must contain only one VMFS datastore!

    Bob, the question is about a datastore, that can be online while expanding.
    I guess you are talking about a single VMDK that goes beyond 2TB, for that the VM needs to be powered off. Your link points to info about a VMDK betond 2TB, not a datastore.
