mmvdisk: Total capacity is the raw space before any vdisk set definitions.
mmvdisk: Free capacity is what remains for additional vdisk set definitions.
16. Use the mmvdisk command set to allocate the new space.
An example of adding the new storage to an existing file system is as follows:
• Define a VDisk set that is tied to the existing recovery group. This example assumes that an existing
VDisk code is 8+2p (default), block-size is 4 MiB (default), and set-size is 80% (default). Because
the decluster array size is doubled after new 12 drives, the set-size is set to 40% to keep the new
VDisk size same as the original VDisk size. For information about non-default configurations, see
IBM Spectrum Scale RAID: Administration in IBM Elastic Storage Server documentation.

mmvdisk: Vdisk set 'vs_fs3200_2' has been defined.
