Abstract:
1. A method for updating directory information in a distributed storage network (DSN) memory, comprises: dispersed storage error encoding data to produce a plurality of sets of encoded data slices; transmitting the plurality of sets of encoded data slices to the DSN memory for storing the plurality of sets of encoded data slices; determining to update directory metadata stored in a local cache memory in response to storing the plurality of sets of encoded data slices in the DSN memory; updating the directory metadata stored in the local cache memory; determining to synchronize the directory metadata stored in the local cache memory with directory information stored in the DSN memory; in response to determining to synchronize the directory metadata, dispersed storage error encoding the directory metadata to produce a plurality of sets of encoded directory metadata slices; and transmitting the plurality of sets of encoded directory metadata slices to the DSN memory for storing the plurality of sets of encoded directory metadata slices with the directory information stored in the DSN memory.
