Abstract: The embodiment of the present application discloses a file resource processing method and apparatus, a device and a medium, relates to a file system processing technology and the field of cloud computing. Herein, the file resource processing method includes the following steps of: receiving a file resource access request of a terminal, and determining a target file resource requested to be accessed by the terminal according to the file resource access request; marking the target file resource as a state of entering a grace period, in response to determining that the file resource access request belongs to a reestablishing resource state request; and executing an access operation corresponding to the file resource access request based on the target file resource, in response to determining that the file resource access request does not belong to the reestablishing resource state request.

Abstract: Embodiments of the present application disclose a file directory traversal method, apparatus, device, and medium, and relate to the field of file system processing technology and cloud computing. The method may include: receiving a current directory traversal request of a terminal for a target directory; determining a directory calling identifier of the terminal by parsing the current directory traversal request; wherein, the directory calling identifier is used for uniquely representing the terminal under the target directory; determining a directory entry currently requested to be called by the terminal under the target directory, according to the current directory traversal request; and sending the determined directory entry to the terminal in accordance with the directory calling identifier.

Abstract: The present disclosure provides a replica processing method based on a raft protocol. The method includes: for a node to be processed corresponding to a raft replica group, determining a replica to be cleaned corresponding to the node, the raft replica group including a first node and at least one second node; for the node, obtaining replica configuration information of the raft replica group, the replica configuration information including one or more primary replicas stored by the first node and one or more secondary replicas stored by the at least one second node; and for the node, determining whether the replica configuration information includes the replica to be cleaned, if yes, reserving the replica to be cleaned, and if no, deleting the replica to be cleaned. The present disclosure also provides a replica processing node, a distributed storage system, a server, and a computer-readable medium.
