Dynamic storage map redirection

A computing device of a group of computing devices of a dispersed storage network (DSN), the computing device comprises:

• an interface;
• a local memory;
• and
• a processing module operably coupled to the interface and the local memory, wherein the processing module functions to:
• migrate, by a first DS (dispersed storage) unit, a dispersed storage network (DSN) address sub-range from the first DS unit to a second DS unit of a set of DS units;
• migrate, by the second DS unit, a DSN address sub-range from the second DS unit to a third DS unit;
• and
• issue, by the third DS unit, a range owner message with regards to the DSN address sub-range to a home DS unit.

A system comprises:

• an interface;
• a local memory;
• dispersed storage network (DSN);
• and
• a processing module operably coupled to the interface, the local memory and the DSN, wherein the processing module functions to:
• migrate, by a first DS (dispersed storage) unit, a dispersed storage network (DSN) address sub-range from the first DS unit to a second DS unit of a set of DS units;
• migrate, by the second DS unit, a DSN address sub-range from the second DS unit to a third DS unit;
• issue, by the third DS unit, a range owner message with regards to the DSN address sub-range to a home DS unit;
• generate a DS unit access request based on a DSN address;
• identify a target DS unit based on the DSN address;
• determine whether the target DS unit has already been identified;
• and
• indicate an error when the target DS unit has not already been identified.
