  • Patent number: 9418097
    Abstract: Implementations are provided herein for sending event notifications based on modifications to files and/or directories. When a file is read, modified or changed under the conditions for a registered event notification, a consistency point can be established. An impact list can then be determined based on the target. It can then be determined whether the version of event caches associated with the files and folders identified in the impact list match a global event cache version determined at the time of the consistency point. If the event caches are an old version, the system call can be restarted, and the event caches can be rebuilt to the current version. If the event caches of the impact list are current, the file system operation can be performed, and notifications can be sent based on the set of listeners identified within the current set of event caches.

  • Patent number: 8356013
    Abstract: In one embodiment, a user or client device is connected to a distributed file system comprised of one or more physical nodes. The data on each of the physical nodes store metadata about files and directories within the file system. Some of the embodiments permit a user to take a snapshot of data stored on the file system. The snapshot may include a single file, a single directory, a plurality of files within a directory, a plurality of directories, a path on the file system that includes nested files and subdirectories, or more than one path on the file system that each includes nested files and directories. In an embodiment, a snapshot tracking data structure is maintained for efficient creation and deletion of the snapshot.

  • Patent number: 8286029
    Abstract: In some embodiments, storage devices, such as a storage drive or a storage node, in an array of storage devices may be reintroduced into the array of storage devices after a period of temporary unavailability without fully rebuilding the entire previously unavailable storage device.

  • Patent number: 8195905
    Abstract: Embodiments of the invention relate generally to incremental computing. Specifically, embodiments of the invention include systems and methods that provide for the concurrent processing of multiple, incremental changes to a data value while at the same time monitoring and/or enforcing threshold values for that data value. For example, a method is provided that implements domain quotas within a data storage system.

  • Patent number: 8015216
    Abstract: Embodiments of the invention relate generally to incremental computing. Specifically, embodiments of the invention include systems and methods that provide for the concurrent processing of multiple, incremental changes to a data value while at the same time monitoring and/or enforcing threshold values for that data value. For example, a method is provided that determines whether multiple incremental changes to a data field could pass a threshold based on keeping track of a possible value range for the data field.

The data on each of the physical nodes store metadata about files and directories within the file system. Some of the embodiments permit a user to take a snapshot of data stored on the file system. The snapshot may include a single file, a single directory, a plurality of files within a directory, a plurality of directories, a path on the file system that includes nested files and subdirectories, or more than one path on the file system that each includes nested files and directories. According to one embodiment, the system stores representations of the snapshots that govern a file or directory and its descendants within metadata associated with that file or directory. In one embodiment, before modifying a file or directory, the system updates the representations of the governing snapshots by traversing the metadata of ancestors of the file or directory.
