  • Distributed file system having separate data and metadata and providing a consistent snapshot thereof
    Patent number: 9235479
    Abstract: Described are techniques for creating a snapshot of a distributed file system or a file thereof. The distributed file system includes metadata file systems storing metadata about files in the distributed file system and includes data file systems storing file content data. Quiescing is performed for requests affecting the distributed file system, or a file thereof, for which a snapshot is being created. A snapshot of metadata is obtained. For the distributed file system, this includes a snapshot of each metadata file system. For a file, this includes a snapshot of the file's metadata. A snapshot of file data is obtained. For distributed file systems, this includes a snapshot of each data file system. For a file, this includes a snapshot of the file's data. Unquiescing is performed for requests affecting the distributed file system, or the file thereof, upon successful completion of obtaining snapshots of metadata and file data.

  • Providing file system quota support for a file system having separated data and metadata
    Patent number: 8892507
    Abstract: 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.

  • File server system having high-speed write execution
    Patent number: 5218695
    Abstract: A file server system selectively stores and provides access to files across a local network. The system utilizes adaptive request batching, disk pre-allocation, and shadow inode logic to enable data writing operations to be executed at high speed, while conforming to stateless protocol requirements.
