摘要: File system independent techniques and mechanisms for replicating files on multiple devices are provided, migrating files from one device to another (for purposes of reliability, increased bandwidth, load balancing, capacity expansion, or reduced cost), and propagating updates from a master copy to remote replicas. The mechanisms involve work queues and asynchronous file migration daemons that operate independently from and in parallel with the primary client-server and network protocol to on-disk storage data paths.

摘要: A storage system includes a plurality of storage servers that store a plurality of files, a monitor module, and a redirector module. The monitor module monitors usage information associated with the plurality of storage servers. The redirector module determines, based on the monitored usage information, a storage server in the plurality of storage servers to service a session from a client. The redirector module then instructs the client to establish the session with the determined storage server.

摘要: A scalable clustered storage system includes a control node and a plurality of storage nodes. The control node stores object identifiers and location information associated with a plurality of files. The plurality of storage nodes stores the plurality of files. A storage node in the plurality of storage nodes receives a request for a file in a file system from a client. The storage node then communicates with the control node to determine an object identifier and location information associated with the file. The storage node accesses the file in the file system to service the request from the client using the object identifier and location information associated with the file.

摘要: A method and apparatus for transparent failover of a filesystem within a computer cluster is provided. For failover protection, a filesystem is physically connected to an active server node and a standby server node. A cluster file system provides distributed access to the filesystem throughout the computer cluster. The cluster file system monitors the progress of each operation performed on the failover protected filesystem. If the active server node should fail during an operation, all processes performing operations on the failover protected filesystem are caused to sleep. The filesystem is then relocated to the standby server node. The cluster file system then awakens each sleeping process and retries each pending operation.

摘要: A system for protection of filesystem data integrity within a computer cluster is provided. The system uses redundant data caches at client and server nodes within the computer cluster. Caching of filesystem data is controlled so that non-shared files are preferably cached at client nodes. This increases filesystem performance within the computer cluster and ensures that failures may not result in a loss of modified filesystem data without a corresponding loss to the process(es) accessing that data. Shared files are cached at the server node and a backup cache node. This protects modified filesystem data against any single node failure.
