Abstract

See full text

The disclosed embodiments disclose techniques for maintaining global name consistency for a distributed filesystem. Two or more cloud controllers collectively manage distributed filesystem data that is stored in one or more cloud storage systems; the cloud controllers ensure data consistency for the stored data, and each cloud controller caches portions of the distributed filesystem. During operation, a cloud controller receives a client request to perform a namespace operation upon a filesystem object. The cloud controller contacts the cloud controller that manages (“owns”) the portion of the global namespace for the distributed filesystem that includes the filesystem object. This second cloud controller ensures the consistency of the filesystem object across the distributed filesystem during the namespace operation.
