A method and mechanism for implementing variable sized extents for a logical volume or file is disclosed. Instead of using extents which all have the same size to form a logical volume, a logical volume includes extents having different extent sizes. A relatively small extent size is used for extents allocated for the first portion of a logical volume, which increases to a larger extent size for extents allocated to a second portion of the logical volume, which again increase one or more times for extents allocated for later portions of the logical volume.
