Balancing storage node utilization of a dispersed storage network

A dispersed storage (DS) module of a dispersed storage network (DSN), the DS module comprises:

• a utilization module, when operable within a computing device, causes the computing device to:
• determine memory space utilization state of a plurality of logical storage nodes of the DSN, wherein DSN memory of the DSN is logically divided into the plurality of logical storage nodes, wherein a DSN address range of the DSN memory is assigned to the plurality of logical storage nodes, wherein a logical storage node of the plurality of logical storage nodes is assigned a portion of the DSN address range, and wherein the memory space utilization state of the logical storage node of the plurality of logical storage nodes is under-utilized, over-utilized, or average;
• and
• an address range assignment module, when operable within the computing device, causes the computing device to:
• when one or more logical storage nodes of the plurality of logical storage nodes is in the over-utilized memory space utilization state and another one or more logical storage nodes of the plurality of logical storage nodes is in the under-utilized memory space utilization state:
• select one of the other one or more logical storage nodes of the plurality of logical storage nodes that is in the under-utilized memory space utilization state to produce a selected logical storage node;
• reassign the portion of the DSN address range assigned to the selected logical storage node to one or more logical storage nodes of the plurality of logical storage nodes that is in the average memory space utilization state to create an address free logical storage node;
• and
• reassign one or more address blocks of the portion of the DSN address range assigned to one of the one or more logical storage nodes of the plurality of logical storage nodes that is in the over-utilized memory space utilization state to the address free logical storage node.
