Abstract
Provided are a computer program product, system, and method for preemptively allocating extents to a data set in a storage system. A data set is comprised of a plurality of extents configured in at least one volume in the storage system. A first extent is allocated to the data set in a first volume to extend the data set. A determination is made as to whether a second extent can be allocated to the data set in the first volume in response to the allocating of the first extent. The second extent in a second volume is allocated for the data set in response to determining that the second extent cannot be allocated to the data set in the first volume.
