SYNCHRONIZING FILE UPDATES BETWEEN TWO CLOUD CONTROLLERS OF A DISTRIBUTED FILESYSTEM

摘要

The disclosed embodiments disclose techniques for synchronizing file updates between two cloud controllers of a distributed filesystem. Two or more cloud controllers collectively manage distributed filesystem data that is stored in the 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 request from a client to access a file in the distributed filesystem. The cloud controller sends a synchronization update request for the file to a second cloud controller and in response receives a synchronization update for the file from the second cloud controller.

1. A computer-implemented method for synchronizing file updates between two cloud controllers of a distributed filesystem, the method comprising:
collectively managing the data of the distributed filesystem using two or more cloud controllers, wherein collectively managing the data comprises storing the data for the distributed filesystem in one or more cloud storage systems, wherein the cloud controllers cache and ensure data consistency for data stored in the cloud storage systems; receiving at a first cloud controller a client request to access a file in the distributed filesystem; sending a synchronization update request for the file to a second cloud controller; and receiving a synchronization update for the file from the second cloud controller in response to the synchronization update request.
