摘要： The disclosed embodiments disclose techniques for transferring and caching a cloud file in a cloud controller. Two or more cloud controllers collectively manage distributed filesystem data that is stored in one or more cloud storage systems; the cloud controllers cache and ensure data consistency for the stored data. During operation, a cloud controller receives a client request for a data block of a target file that is stored in the distributed filesystem but not currently cached in the cloud controller. The cloud controller initiates a request to a cloud storage system for a cloud file containing the requested data block. While receiving the cloud file from the cloud storage system, the cloud controller uses a set of block metadata in the portion of the cloud file that has already been received to determine the portions of the cloud file that should be downloaded to and cached in the cloud controller.

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.

摘要： The disclosed embodiments disclose techniques for restoring an archived file in 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. Furthermore, cloud controllers may archive infrequently-accessed files in an archival cloud storage system. During operation, a cloud controller receives a request from a client system to access an archived file, and restores this archived file from the archival cloud storage system.

摘要： The disclosed embodiments disclose techniques that facilitate the recovery of a virtual machine using 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 in a local storage pool. During operation, a host server executes program instructions for an application in a virtual machine (VM); data associated with this application and/or this virtual machine is stored in the distributed filesystem. Upon detecting a subsequent failure, the system can recover and resume the execution of the virtual machine and application using the previous application and virtual machine data that was stored in the distributed filesystem.

摘要： An apparatus and a method for delegating commands for a network attached storage system is described. A command permission associated with a command to be executed on a Network Attached Storage (NAS) server is delegated to a user of a NAS client having a mounted network filesystem of the NAS server. The command is issued through the filesystem of the NAS client.

摘要： The disclosed embodiments disclose techniques that facilitate the process of performing anti-virus checks 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 write request from a client system that seeks to store a target file in the distributed system. A scan is then performed for this target file. For instance, the scan may be an anti-virus scan that ensures that viruses are not spread to the distributed filesystem or the clients of the distributed filesystem.

摘要： The disclosed embodiments disclose techniques for managing a cloud-based distributed computing environment (CBDCE) that comprises multiple geographically-distributed compute nodes. Multiple services simultaneously execute on the CBDCE compute nodes, with each service comprising multiple service instances that simultaneously execute on multiple distinct compute nodes of the CBDCE. During operation, the system uses a distributed database to track the status of the CBDCE to ensure the ongoing stability and scalability of the CBDCE. Upon receiving a request that is associated with the configuration of the CBDCE, a service accesses CBDCE status information from the distributed database to respond to the request.

摘要： The disclosed embodiments disclose techniques for optimizing caching performance 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 cloud controllers cache portions of the distributed filesystem on hard drives with rotating disk platters. The outside portions of these disk platters have higher I/O bandwidth than the inside portions of the disk platters. During operation, a cloud controller determines that a hot subset of cached data is likely to be accessed frequently by clients, and stores this hot subset to an outside portion of a disk platter. The cloud controller further determines that a cold subset of cache data is less likely to be accessed by clients, and stores the cold subset on an inside portion of a disk platter.
