Abstract: Embodiments of the present disclosure provide a distributed storage method and a distributed storage device. The method includes offline merging, by a first thread service of a distributed storage system, M small files in a file system, generating, by the first thread service, M pieces of metadata in the offline merging process, loading, by a second thread service of the distributed storage system, the M pieces of metadata into a metadata set, searching, by the second thread service, the metadata set for metadata of a first small file when the second thread service receives a first instruction, and performing, by the second thread service, the operation corresponding to the first instruction when the second thread service finds the metadata of the first small file in the metadata set.

Abstract: A system and method for growing crystals is described. The system includes a crucible, a shaft adapted to support the crucible, and an intermediate material between the crucible and the shaft having a coating directly applied to contact surfaces of the crucible and the shaft. The coating includes a compound, such as, a carbide, nitride, oxide, or boride. The method for growing a crystal includes providing an intermediate material between contact surfaces between a shaft and a crucible supported by the shaft prior to melting a charge material in the crucible.
