Zusammenfassung:Embodiments include techniques for metadata verification in a distributed file system, the technique including receiving an input for metadata, the metadata being associated with a file, and acquiring a function lock on a designated region of the file based at least in part on the metadata. The technique also includes hashing the input associated with the metadata into a designated region of the file, and updating the designated region corresponding to the input. The technique includes computing a checksum for the metadata associated with the designated region, updating a journal file based at least in part on the metadata, and releasing the function lock.
