发明名称 Revision synchronization of a dispersed storage network
摘要 A method begins by a processing module receiving a write request message from a dispersed storage (DS) processing module, wherein the write request message includes a slice name, a DS processing module most-recent slice revision, a new slice revision, and an encoded directory slice of directory information regarding storage of data. The method continues with the processing module obtaining, from local memory, a DS unit most-recent slice revision based on the slice name. The method continues with the processing module storing the new slice revision as the DS unit most-recent slice revision and storing the encoded directory slice when the DS unit most-recent slice revision compares favorably to the DS processing module most-recent slice revision.

主权项 1. A method for execution by a dispersed storage (DS) unit, the method comprises: receiving a write request message from a dispersed storage (DS) processing module, wherein the write request message includes a slice name, a DS processing module most-recent slice revision, a new slice revision, and an encoded directory slice of directory information regarding storage of data; obtaining, from local memory, a DS unit most-recent slice revision based on the slice name; and when a revision number of the DS unit most-recent slice revision is same as a revision number of the DS processing module most-recent slice revision: storing the new slice revision as the DS unit most-recent slice revision; andstoring the encoded directory slice.
