Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of computer, in particular to the technical field of cloud storage, and more particularly to a method and apparatus for processing operations of a file system. BACKGROUND

[0002] Two data structures, directory entry dentry and index node inode, are included in a file system. Dentry records the name and inode of a directory or file. Inode records the specific storage location of a directory or file.

[0003] In a distributed file system, a dentry of a child node is added in a parent directory each time a directory or file is created, and an inode also needs to be allocated. However, since the dentry and inode are usually stored in different locations in the distributed file system, this will result in two RPCs (Remote Procedure Call) across servers each time a file or directory is created, thereby affecting the operation performance of the distributed file system.

[0028] Exemplary embodiments of the present disclosure are described herein with reference to the accompanying drawings, which are included to provide a thorough understanding of embodiments of the present disclosure by a person of ordinary skill in the art, and should be considered as illustrative only. Accordingly, persons of ordinary skill in the art will recognize that there are various changes, modifications and alterations that could be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Also, for the sake of brevity and clarity, any description of function and constructions that is well known to those having ordinary skill in the art is omitted.

[0029] Figure 1 is a flowchart of an operation processing method for a file system according to an embodiment of the present disclosure, which can be applicable to the case of quickly creating a directory or a file in a distributed file system, and relates to the technical field of computers, and particularly to the technical field of cloud storage. The method can be performed by an operation processing apparatus for a file system, which is implemented in software and / or hardware, and is preferably configured in an electronic device, such as a computer device or a server. As shown in the figure, the method specifically includes the following steps. Figure 1

[0030] S101, in response to a creation request for a target object, determining a parent directory to which the target object belongs in a file system directory tree, wherein the target object includes a directory or a file.

[0031] S102, creating a directory entry for the target object in the parent directory, and returning a message to the user layer that the target object is created successfully, wherein the directory entry at least includes an index node of the parent directory and metadata information of the target object.

[0032] S103, in response to a target operation of changing the target object, judging whether an index node of the target object exists.

[0033] S104, if not, creating the index node of the target object according to the index node of the parent directory and the metadata information.

[0034] ​In a distributed file system, creating a directory or a file usually requires adding a child node directory entry dentry in its parent directory and updating the attributes of the parent directory, such as modification time and the number of child nodes. The parent directory can be determined according to the creation request in the file system directory tree. In addition, an inode structure needs to be created to record the attributes of the created directory or file.

[0035] In the prior art, a message of successful creation is returned to the user after the dentry and inode structures are created. However, the inode and dentry structures are usually stored in different locations. For example, in a distributed file system CFS (Cloud File Storage), the dentry is recorded in a database, and the inode information is recorded in another data management system. Therefore, creating a directory or a file requires two RPCs across servers, which affects the operation performance of the system.

[0036] In the embodiments of the present application, a message of successful creation of the target object is returned to the user layer after the dentry of the target object is created in the parent directory. Therefore, creating a directory or a file requires only one RPC, which improves the efficiency. In addition, the dentry includes the inode of the parent directory and the metadata of the target object, such as the creation time of the file, the user ID, the user group ID, the permission-related information, and the file type.

[0037] In the embodiments of the present application, the creation of the inode is postponed until the client performs a target operation on the target object. For example, the target operation can be writing, setting attributes, establishing a hard link, and creating a subdirectory. In response to the target operation on the target object, it is determined whether the inode of the target object exists. If the inode does not exist, the inode of the target object is created.

[0038] Specifically, in order to ensure the integrity of the file system, when the user performs Lookup (finding the dentry of a specified file), the inode of the parent directory and the metadata of the target object included in the dentry are returned to the client of the user. Then, when the client performs the target operation on the target object, the inode of the parent directory and the metadata of the target object are carried. In this way, when it is determined that the inode of the target object does not exist, it indicates that the user has not used the target object after creating the target object. Therefore, the inode of the target object can be created according to the inode of the parent directory and the metadata of the target object. For example, the target operation and the creation of the inode can be performed simultaneously.

[0039] In one embodiment, the inode and metadata information of the parent directory can be added in the extend_fh field.

[0040] The technical solution of the embodiments of the present disclosure first does not create an inode when creating a directory or a file, but adds the inode of the parent directory and the metadata information of the target object in the created dentry, and then creates the inode according to the inode of the parent directory and the metadata information of the target object when performing other operations such as writing that change the directory or the file, so that the two RPCs originally required in the creation process become one RPC, thereby improving the operation performance.

[0041] Figure 2 is a schematic diagram of creating an inode in the operation processing method according to the embodiments of the present disclosure. The present embodiment is further optimized on the basis of the above-mentioned embodiments. As shown in Figure 2 The method specifically includes the following:

[0042] S201, generating an inode creation request according to the inode of the parent directory and the metadata information.

[0043] S202, packing the request of the target operation and the inode creation request to obtain a request package.

[0044] S203, creating the inode of the target object when performing the target operation according to the request package.

[0045] Specifically, first, the inode creation request is generated according to the inode of the parent directory and the metadata information, then the request of the target operation and the inode creation request are packed to obtain a request package, and then the inode of the target object is created when performing the target operation according to the request package. Since the target operation itself also requires one RPC, the creation of the inode of the target object when performing the target operation can change the two RPCs originally required in the target object creation process into one RPC, thereby improving the operation performance.

[0046] In an implementation manner, when performing the target operation, the inode of the target object can be written into the super block of the file system. For example, when performing, the data to be written corresponding to the target operation and the super block corresponding to the inode to be created are first generated in the memory, and then the data to be written and the super block are written atomically.

[0047] In addition, in an embodiment, the method of the present disclosure further comprises: in response to a deletion operation on the target object, deleting the index node of the target object after a delay set time. The purpose of this is to ensure that the user has the opportunity to perform a recovery operation after mistakenly deleting data, and to ensure the correctness of the file system. Since the super block object (or inode) is not deleted immediately after deleting a file or directory, if the user finds that the super block does not exist when performing a target operation to change the target object, it can be ensured that it has not been created, and thus the super block object can be directly created.

[0048] Specifically, the index node or super block of the target object does not exist, which usually has two possibilities, one is deleted, and the other is not created. In order to ensure the correctness of the asynchronous creation of inode in the present disclosure, it is necessary to ensure that when it is judged that the index node of the target object does not exist, it is because it has not been created, rather than being deleted. Therefore, on the one hand, the deletion operation on the target object is to delete the index node of the target object after a delay set time, and on the other hand, the expiration time of the file handle of the file system is configured to be less than the set time. Since Lookup is usually performed before the open file operation, if the index node is deleted, the inode of the file cannot be obtained. Therefore, it is impossible to receive a write or setattr operation request to change the file or directory after the set time set by the delay of deleting the index node. Then, when such a request is received, if it is judged that the index node does not exist, it can only be because it has not been created. Even if another user deletes this directory or file one second before these operations occur, the inode created in response to these operations will be asynchronously deleted at the set time subsequently.

[0049] Figure 3 is a schematic diagram of deleting a target object in the operation processing method according to the present disclosure. This embodiment is further optimized on the basis of the above-mentioned embodiment. As shown in Figure 3 , the method specifically comprises the following:

[0050] S301, in response to a deletion operation on the target object, adding a deletion mark indicating a deletion timestamp to the name of the target object in the directory entry of the parent directory of the target object.

[0051] S302, adding the name of the target object with the deletion mark and the data location information to the garbage collection station.

[0052] S303, asynchronously deleting according to the load of the file system and the deletion mark through the garbage collection station.

[0053] The deletion operation on the target object is, for example, an unlink operation, indicating deleting a file or deleting a hard link. In the directory entry of the parent directory of the target object, a deletion mark indicating a deletion timestamp is added to the name of the target object, which can be, for example: adding a special symbol, such as ' / ', before the name; or adding a deletion timestamp (nanosecond level) after the name. For example, after the file a is deleted, the name after adding the deletion mark is: ' / a / 1683508977716442953 / a'. The number represents the deletion timestamp. After adding the deletion mark, the attributes of the parent directory are updated, including the modification time and file statistics information.

[0054] Then, the name and data location information of the target object with the deletion mark are added to the garbage collection station GC. For example, the file name of the deleted file and the location information in the metadata pool, and the location information of the deleted object in the data pool.

[0055] In the embodiments of the present disclosure, the target object is not immediately deleted, but is deleted asynchronously by the GC according to the load of the file system and the deletion mark. For example, the GC can be set to delete after three days. In order to avoid the GC causing too large a load on the system, the speed of deletion can be automatically adjusted by the GC according to the real-time load. At the same time, the to-be-deleted targets can be sorted according to the deletion marks of the to-be-deleted targets, and the targets that are added to the GC earlier are preferentially deleted.

[0056] Therefore, by using the above-mentioned idle-time delayed deletion method of directories or files, the embodiments of the present disclosure can further improve the system performance and improve the processing efficiency of the system.
