Converting a multi-volume file system to a single volume file system
Because data can be relocated among volumes in a multi-volume file system, you can convert a multi-volume file system to a traditional, single volume file system by moving all file system data onto a single volume. Such a conversion is useful to users who would like to try using a multi-volume file system or Dynamic Storage Tiering, but are not committed to using a multi-volume file system permanently.
There are three restrictions to this operation:
The single volume must be the first volume in the volume set
The first volume must have sufficient space to hold all of the data and file system metadata
The volume cannot have any allocation policies that restrict the movement of data
