摘要： A network storage system comprises data storage, one or more file system APIs, and a metadata handler. The data storage can comprise file data and associated metadata. The file system APIs can be configured to read and write file data and metadata to and from the data storage. The metadata handler can have a library of functions for handling the metadata. The library can include a metadata blob creation function and a metadata blob extraction function. The metadata blob creation function cooperates with the file system APIs to read source metadata associated with specified file data and creates and populates a metadata blob from which a substantial copy of the source metadata can be generated. The metadata blob extraction function receives at least a metadata blob, extracts information from the metadata blob, and cooperates with the file system APIs to generate destination metadata, a substantial copy of the source metadata.

摘要： Described are techniques for performing quota management in a distributed file system. An allocation quota specifies an upper limit of storage for allocation for a quota set of the distributed file system. The distributed file system includes metadata file system(s) and data file system(s). For files in the distributed file system, metadata is stored in one of the metadata file systems and file content data is stored in the data file systems. A quota coordinator partitions the allocation quota among the data file systems. The data file systems are allocators of storage and each receives a portion of the allocation quota specifying an upper limit of storage that the data file system has available for allocation for the quota set. Storage is allocated for client requests. The storage allocation is performed by each of the data file systems in accordance with the portion of the allocation quota assigned.

摘要： A clustered network storage system includes a policy based storage efficiency management framework to allow users to more efficiently manage storage efficiency attributes on a plurality of storage objects in the clustered network storage system. The storage efficiency management framework includes a policy database for storing a plurality of polices, each of which includes a plurality of attributes. Each storage object in the clustered network storage system is assigned a policy. Storage efficiency operations can then be initiated by a storage efficiency engine according to the policies assigned to the storage objects by sending a single trigger to each node in the clustered network storage system and the storage efficiency engine determining on which storage objects to perform the storage efficiency operations.

摘要： A clustered network storage system includes a management module and a resource allocation mechanism configured to allow remote management of node resources from the management module while preventing resource over-commitment due to the remote management. Preventing resource over-commitment includes conditionally granting access to the resources of a node according to a credit based system. Preventing resource over-commitment further includes scheduling jobs that access the resources of the node according to a prioritization scheme.

摘要： A method of managing file permissions in a remote file storage system includes defining permissions for the remote file storage system and controlling access to objects on the remote file storage system according to the permissions of the remote file storage system. The permissions are transferred to a client file storage system remote from the remote file storage system, and access to objects on the client file storage system is controlled according to the permissions of the remote file storage system. A remote file storage system includes a permissions file generator operative to generate a permissions file, which is transmitted to a client file storage system for enforcement at the client file storage system.
