Resolving write request conflicts in a dispersed storage network

A non-transitory computer readable storage medium comprises:

• at least one memory section that stores operational instructions that, when executed by one or more processing modules of a computing device of a dispersed storage network (DSN) to resolve conflicts arising from substantially concurrent write requests regarding a data object, causes the computing device to:
• issue a write request for a dispersed storage error encoded version of the data object to storage units of the DSN;
• receive, in response to the write request, write responses from at least some of the storage units, wherein each of the write responses includes either:
• a lock indication;
• or
• a non-lock indication and conflict information;
• determine whether at least a write threshold number of write responses have been received that include the lock indication;
• and
• when less than the at least a write threshold number of write responses have been received that include the lock indication:
• process the conflict information to identify one or more other write requests of the substantially concurrent write requests that have a higher priority than the write request;
• and
• establish a write request retry time frame based on the one or more other write requests that have the higher priority.

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:
• issue, via the interface, a write request for a dispersed storage error encoded version of a data object to storage units of the DSN, wherein substantially concurrent write requests regarding the data object includes the write request;
• receive, via the interface in response to the write request, write responses from at least some of the storage units, wherein each of the write responses includes either:
• a lock indication;
• or
• a non-lock indication and conflict information;
• determine whether at least a write threshold number of write responses have been received that include the lock indication;
• and
• when less than the at least a write threshold number of write responses have been received that include the lock indication:
• process the conflict information to identify one or more other write requests of the substantially concurrent write requests that have a higher priority than the write request;
• and
• establish a write request retry time frame based on the one or more other write requests that have the higher priority.
