Temporary relocation of data within local storage of a dispersed storage network

A processing system of a storage unit comprises:

• a plurality of memory devices;
• at least one processor;
• and
• a memory that stores operational instructions, that when executed by the at least one processor cause the processing system to:
• execute a write request to write a first data slice by:
• identifying, from the plurality of memory devices of the storage unit, a first memory device that is designated for storage of the first data slice based on determining a slice name of the first data slice compares favorably to a namespace assigned to the first memory device;
• determining that the first memory device is unavailable;
• performing a function on the slice name of the first data slice to identify a second memory device from the plurality of memory devices of the storage unit for temporary storage the first data slice in response to determining that the first memory device is unavailable;
• and
• storing the first data slice in the second memory device in response to identifying the second memory device;
• determine that the first memory device is available at a time after execution of the write request;
• and
• migrate the first data slice from storage in the second memory device to storage in the first memory device in response to determining that the first memory device is available.

A non-transitory computer readable storage medium comprises:

• at least one memory section that stores operational instructions that, when executed by a processing system of a network that includes a processor and a memory, causes the processing system to:
• execute a write request to write a first data slice by:
• identifying, from a plurality of memory devices, a first memory device that is designated for storage of the first data slice based on determining a slice name of the first data slice compares favorably to a namespace assigned to the first memory device;
• determining that the first memory device is unavailable;
• performing a function on the slice name of the first data slice to identify a second memory device from the plurality of memory devices for temporary storage the first data slice in response to determining that the first memory device is unavailable;
• and
• storing the first data slice in the second memory device in response to identifying the second memory device;
• determine that the first memory device is available at a time after execution of the write request;
• and
• migrate the first data slice from storage in the second memory device to storage in the first memory device in response to determining that the first memory device is available.
