摘要:
A system and method efficiently guarantees data consistency to clients for one or more data containers stored on a plurality of volumes configured as a striped volume set (SVS) and served by a plurality of nodes connected as a cluster. Data consistency guarantees of data containers stored on the SVS is generally provided by delegating to data volumes (DVs) sufficient authority to autonomously service input/output (I/O) requests directed to the containers using attributes, such as timestamps, of the containers. Specifically, a DV is only allowed to service I/O requests, e.g., read and write operations, to a data container, such as a file, if it has a valid ticket book for the file. A DV requests and is granted the ticket book from a container attribute volume (CAV) on a per-file basis.
