Cohesity has been granted a patent for a method that involves identifying file system objects, inserting update intents into associated data structures, modifying the objects based on the intents, and removing the intents after modification. The method also includes obtaining node-level and process-wide locks for file system data structures and performing file system operations, such as creating a file in a directory. If a crash occurs before the second update intent is stored, the method determines that the operation was not successful.

The patent is granted for a method of performing file system operations
A recently granted patent (Publication Number: US11775485B2) describes a method for performing file system operations in a distributed file system. The method involves identifying multiple file system data structures to modify, obtaining node-level and process-wide locks for each of these structures, and then performing the file system operation.
The method specifically addresses the creation and deletion of files within directories. When creating a file, the method involves storing update intents in the associated inodes of the directory and the file itself. If the file crashes after the first update intent is stored but before the second update intent is stored, the method determines that the file system operation was not successful.
The patent also mentions the use of a distributed lock service to obtain the necessary locks for the file system data structures. This includes requesting and receiving node-level locks, as well as waiting for locks that are currently being used by other computing nodes in the distributed file system.
Additionally, the patent includes a computer program product embodied in a non-transitory computer-readable medium. This product contains computer instructions for implementing the method described above, including the creation and deletion of files and the handling of update intents.
In summary, the granted patent outlines a method for performing file system operations in a distributed file system. The method involves obtaining locks for file system data structures, storing update intents, and determining the success of the file system operation based on the occurrence of crashes. The patent also includes a computer program product for implementing this method.
