Abstract:
A method begins by detecting an inconsistency between a first version of an object at a first storage target within the DSN and a second version of the object at second storage target of the DSN. The method continues by accessing an operation log of the DSN to identify relevant entries regarding the object. The method continues by selecting an inconsistency resolution approach from a list of inconsistency resolution approaches based on a type of inconsistency between the first and second versions of the object and based on the relevant entries. When the selected inconsistency resolution approach is a multiple version storage option, the method continues by sending a first storage request to the first storage target to store the first version of the object and a second storage request to the second storage target to store the second version of the object.
