Resize a FS with space from a specific disk

In a disk group, where some volumes are stripped and some are concat, while adding disk space to a concat volume, care needs to be taken.

For STRIPE volumes, when adding a new disk, the whole stripe has to be relayedout.

For CONCAT volumes, it is straight extension but the disk that was added needs to be used only for this volume and shouldn't mix with the STRIPE volumes.
