A method begins by a dispersed storage (DS) processing module determining memory space utilization state of logical storage nodes of a dispersed storage network DSN. When a logical storage node is in an over-utilized memory space utilization state and another logical storage node is in an under-utilized memory space utilization state, the method continues with the DS processing module selecting the other logical storage node to produce a selected logical storage node and reassigning a portion of a DSN address range assigned to the selected logical storage node to a logical storage node that is in an average memory space utilization state to create an address free logical storage node. The method continues with the DS processing module reassigning address blocks assigned to the logical storage node that is in the over-utilized memory space utilization state to the address free logical storage node.
