Method, device and storage medium for renaming file system objects

An apparatus for renaming a file system object, comprising:

• at least one processor;
• and
• a memory in communication with the at least one processor,
• wherein the memory stores instructions executable by the at least one processor, and the instructions are executed by the at least one processor, to cause the at least one processor to execute:
• determining a renaming type for a file system object according to a received renaming request, wherein the file system object comprises a directory and a file;
• determining, according to the renaming type, data processing operations respectively corresponding to a plurality of servers, comprising:
• determining, according to the renaming type, the data processing operations respectively corresponding to the plurality of servers and an execution order of the data processing operations respectively corresponding to the plurality of servers,
• wherein the plurality of servers comprise a first server storing structure information of the directory, a second server storing attribute information and structure information of the file and attribute information of the directory, and a third server storing content data of the file;
• executing, through the plurality of servers, the data processing operations respectively corresponding to the plurality of servers to rename the file system object, comprising:
• executing, through the plurality of servers, the data processing operations respectively corresponding to the plurality of servers according to the execution order to rename the file system object;
• and
• wherein the determining, according to the renaming type, the data processing operations respectively corresponding to the plurality of servers and the execution order of the data processing operations respectively corresponding to the plurality of servers comprises:
• determining, in response to determining that the renaming type is an operation of renaming a source directory, the execution order as:
• a conflict loop detection operation corresponding to the first server, a directory attribute update operation corresponding to the second server, and a directory structure update operation corresponding to the first server,
• wherein the operation of renaming the source directory is used to represent that the source directory is transferred from a source parent directory to a destination parent directory;
• the conflict loop detection operation is used to lock the source directory, a destination directory obtained after the source directory is transferred to the destination parent directory, a node between the source directory and a target ancestor directory and a node between the destination directory and the target ancestor directory, and the target ancestor directory is a closest common ancestor directory of the source directory and the destination directory;
• the directory attribute update operation is used to update attribute information of the source parent directory and attribute information of the destination parent directory;
• and the directory structure update operation is used to update structure information of the source directory.

A non-transitory computer readable storage medium, storing a computer instruction, wherein the computer instruction, when executed by a computer, causes the computer to execute:

• determining a renaming type for a file system object according to a received renaming request, wherein the file system object comprises a directory and a file;
• determining, according to the renaming type, data processing operations respectively corresponding to a plurality of servers, comprising:
• determining, according to the renaming type, the data processing operations respectively corresponding to the plurality of servers and an execution order of the data processing operations respectively corresponding to the plurality of servers,
• wherein the plurality of servers comprise a first server storing structure information of the directory, a second server storing attribute information and structure information of the file and attribute information of the directory, and a third server storing content data of the file;
• and
• executing, through the plurality of servers, the data processing operations respectively corresponding to the plurality of servers to rename the file system object, comprising:
• executing, through the plurality of servers, the data processing operations respectively corresponding to the plurality of servers according to the execution order to rename the file system object;
• and
• wherein the determining, according to the renaming type, the data processing operations respectively corresponding to the plurality of servers and the execution order of the data processing operations respectively corresponding to the plurality of servers comprises:
• determining, in response to determining that the renaming type is an operation of renaming a source directory, the execution order as:
• a conflict loop detection operation corresponding to the first server, a directory attribute update operation corresponding to the second server, and a directory structure update operation corresponding to the first server,
• wherein the operation of renaming the source directory is used to represent that the source directory is transferred from a source parent directory to a destination parent directory;
• the conflict loop detection operation is used to lock the source directory, a destination directory obtained after the source directory is transferred to the destination parent directory, a node between the source directory and a target ancestor directory and a node between the destination directory and the target ancestor directory, and the target ancestor directory is a closest common ancestor directory of the source directory and the destination directory;
• the directory attribute update operation is used to update attribute information of the source parent directory and attribute information of the destination parent directory;
• and the directory structure update operation is used to update structure information of the source directory.
