technical field

Embodiments of the present invention relate to the technical field of data processing, and in particular, to a method, apparatus, server, and storage medium for object writing.

Background technique

With the gradual increase in the storage of multimedia files, Ceph, as one of the file system alternatives for Linux systems, usually adopts the Ceph File System (Ceph File System, CephFS) to store various system files operated by clients to systems at different levels directory. At this time, multiple clients write files to the system directory under CephFS. There may be a problem that a certain directory is overused and other directory space is wasted. Therefore, there is a directory quota requirement in the file system.

At present, the client will access CephFS in two ways: kernel mount and File System in UserSpace (FUSE) mount. At this time, the client function will be integrated into the Linux kernel when the kernel mounts, which cannot be controlled. CephFS quotas in the system directory; while FUSE will directly embed the corresponding quota check logic in the FUSE client to control the quota of each system directory under CephFS, but the FUSE client needs to start a user space process to provide A file access interface is used to set the quota. At this time, the access path of the system directory is long, resulting in poor quota performance.

Detailed ways

The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, the drawings only show some but not all structures related to the present invention. Furthermore, the embodiments of the invention and the features of the embodiments may be combined with each other without conflict.

The embodiments of the present invention are mainly aimed at that in the existing CephFS system, when the client performs a corresponding write operation (such as writing a new file, creating a new directory, or creating a file soft and hard link in the CephFS system, etc.), due to different There is a corresponding quota defect when setting quotas on the system directory in the mount mode, which leads to the problem of excessive writing in a certain directory, directly through the metadata server (Metadata Server, MDS) in the CephFS system. The corresponding quota information is set for the corresponding directory, without any changes to the client, and only when the specified write volume of the object to be written is less than the remaining permitted quota of the currently specified write directory, and less than the write directory on each direction. Only when the remaining permission quota of the associated directory at the directory level is used, the object to be written will be written to the write directory, so that the object to be written can uniformly meet the quota requirements of the write directory and each associated directory, and effectively avoid different objects. Overwriting to a single directory improves the adaptability of writing objects in different directories.

Example 1

FIG. 1A is a flowchart of a method for writing an object according to Embodiment 1 of the present invention. This embodiment is applicable to a situation in which any object is written in a system directory of various file systems. The object writing method provided in this embodiment may be executed by the object writing apparatus provided in this embodiment of the present invention, and the apparatus may be implemented by means of software and/or hardware, and is integrated in the server that executes the method, the The server may be a metadata server within the file system for processing various types of object metadata.

Specifically, referring to FIG. 1A , the method may include the following steps:

S110: Find out the associated directories of the write directory specified by the to-be-written object at each upper directory level.

Specifically, this embodiment is mainly for the client to perform the corresponding write operation in each system directory of the CephFS system. At this time, the object to be written is any target specified by the client to write in a certain directory, such as a newly created object. At the same time, when the CephFS system is initially set up, the corresponding directory levels will be preset according to the writing requirements of different objects, and corresponding system directories will be created under different directory levels, such as under the CephFS system. The entire object storage area is the first-level directory, and multiple subdirectories are created under the first-level directory as the second-level directory, and multiple subdirectories are created again under each second-level directory as the third-level directory. , and so on, so that there is a corresponding superior-subordinate relationship between each directory under the CephFS system; at this time, the client can instruct to write the corresponding object in any specific directory under the CephFS system, and the specific directory is used as this embodiment. in the write directory.

Optionally, after the client performs a corresponding write operation in a certain directory of the CephFS system, the MDS server will first analyze the object to be written specified by the client in this operation, such as a newly created directory, file or file. Soft and hard links, etc., as shown in Figure 1B, at the same time, find the write directory currently specified by the object to be written in each directory of the CephFS system, and then start from the directory level where the write directory is located, and check each directory upwards in turn. level, so as to find the target directory containing the write directory in each upper directory level of the write directory, as the associated directory of the write directory in each upper directory level in this embodiment.

Exemplarily, if the client currently instructs to write a new file in a specific directory under the third-level directory of the CephFS system, the new file is the object to be written in this embodiment, and the specific directory As the write directory in this embodiment, the directory containing the specific directory under the first-level directory and the second-level directory is the associated directory in this embodiment.

S120, if the specified write amount of the object to be written is less than the remaining permission quota of the write directory and less than the remaining permission quota of the associated directory, write the object to be written into the write directory.

Optionally, in order to avoid excessive writing by the client in a certain directory of the CephFS system, this embodiment will pre-set corresponding quotas for each directory under different directory levels to require the amount of object data written in the directory. The quota set under the directory cannot be exceeded; at this time, each directory under different directory levels will match the corresponding remaining license quota according to the quota under the directory and the amount of written object data. When writing a corresponding object, it is first necessary to analyze whether the currently written data volume meets the requirements of the remaining license quota in the corresponding directory to prevent excessive writing of a certain directory.

Specifically, in order to improve the adaptability of different objects to be written in each directory, the MDS server first calculates the to-be-written after finding out the associated directories of the write directory specified by the object to be written under each upper directory level. The write directory currently specified by the input object and the remaining license quota of each associated directory found at the current moment. At this time, since the write directory specified by the object to be written belongs to a subdirectory under each associated directory, if subsequent When the object to be written is written to the write directory, the amount of data written in the write directory and each associated directory will increase accordingly. Therefore, when the object to be written is written to the currently specified Before writing to the directory, in order to avoid excessive writing to a certain directory, first analyze the specified write volume of the object to be written in this operation, and then judge in turn whether the specified write volume of the object to be written is less than the write directory. and the remaining license quota of each associated directory, that is to say, if the object to be written is subsequently written to the write directory, whether there is an amount of data written in a certain directory in the write directory and each associated directory Exceeds the set quota, causing the directory to overwrite objects; if the specified write volume of the object to be written is less than the remaining permission quota of the write directory, and less than the remaining permission quota of each associated directory, it indicates that the write directory If there is remaining space in each associated directory to write the object to be written, and there is no problem of excessive writing in a certain directory, the object to be written is directly written to the currently specified write directory.

In addition, when this embodiment judges in turn whether the specified write amount of the to-be-written object is less than the remaining permission quota remaining in the write directory and each associated directory, there is another situation: if the specified write amount of the to-be-written object is written If the amount is greater than or equal to the remaining license quota of the write directory, or is greater than or equal to the remaining license quota of the associated directory, the object to be written is prohibited from being written in the write directory.

Specifically, if the specified write volume of the object to be written is greater than or equal to the remaining permission quota of the write directory, or greater than or equal to the remaining permission quota of an associated directory, it means that if the object to be written is written to the write directory After that, the amount of data written to the write directory or an associated directory will exceed the set quota, resulting in the problem of excessive writing to the write directory or an associated directory. The object to be written is written in the write directory, which effectively avoids excessive writing to a single directory by different objects.

The technical solution provided by this embodiment firstly finds out the associated directories of the currently specified writing directory of the object to be written in each upper and lower directory level, only if the specified writing amount of the object to be written is less than the remaining amount of the writing directory Only when the permission quota is less than the remaining permission quota of each associated directory, the object to be written will be written to the writing directory, so that the object to be written can uniformly meet the quota of the specified writing directory and each associated directory. requirements, to prevent the situation that the quota requirements of the write directory are met, but the quota requirements of an associated directory under the upward directory level are exceeded. At the same time, the remaining license quota of the write directory and the associated directory can be limited, which can effectively avoid the impact of different objects on a single directory. overwriting, improving the adaptability of object writing in different directories.

Embodiment 2

FIG. 2A is a flowchart of a method for writing an object according to Embodiment 2 of the present invention, and FIG. 2B is a schematic diagram of the principle of determining the remaining license quota of a write directory and each associated directory in the method provided by Embodiment 2 of the present invention. This embodiment is optimized on the basis of the above-mentioned embodiment. Specifically, as shown in FIG. 2A , this embodiment provides a detailed explanation for the specific determination process of the write directory currently specified by the object to be written and the remaining license quota under each associated directory.

Optionally, as shown in FIG. 2A , this embodiment may include the following steps:

S210: Set a corresponding upper quota limit for the specified directory in advance according to the directory quota requirement, and record the latest written total amount of each directory in real time.

In this embodiment, when the CephFS system performs any file operation, the MDS server can monitor in real time whether there is a corresponding directory quota requirement for the object written in a certain directory by the administrator at the current moment, so that the specified directory can be written at any time at any time. Set the corresponding quota upper limit; for example, if the administrator requires that the amount of written data in some specified directories at the current moment cannot exceed a certain upper limit, otherwise it will cause the problem of excessive writing of the directory, the administrator will The client will execute the quota trigger operation in the specified directory accordingly. When the MDS server detects the quota trigger operation, it will determine the current directory quota requirement by analyzing the quota trigger operation. The directory quota requirement carries the current existence. The specified directory required by the quota, and the quota upper limit required by each specified directory. Therefore, after determining the specified directory carried in the current directory quota demand and the quota upper limit corresponding to each specified directory, the MDS server will assign the quota to each specified directory. Set the corresponding quota upper limit; at the same time, in order to accurately determine the remaining license quota of the corresponding directory in the subsequent object writing process, the latest written total amount of each directory under the CephFS system will also be recorded in real time, so as to accurately analyze each directory. The remaining license quota of , to ensure the adaptation accuracy of different objects written in each directory.

S220: Find out the associated directories of the write directory specified by the to-be-written object at each upper directory level.

S230 , for each directory in the write directory and the associated directory, determine the remaining permitted quota of the directory according to the quota upper limit of the directory and the latest total written amount.

Optionally, after finding out the associated directories of the write directory specified by the object to be written at each upper directory level, since the write directory specified by the object to be written belongs to a subdirectory under each associated directory, if When the object to be written is subsequently written to the write directory, the amount of data written in the write directory and each associated directory will increase accordingly. Therefore, when the object to be written is written to the current directory Before the specified write directory, in order to avoid excessive writing of a directory, it is necessary to analyze the specified write amount of the object to be written in this operation, and the remaining permission of each directory in the write directory and each associated directory. The size between the quotas; at this time, as shown in FIG. 2B , in this embodiment, for each directory in the write directory specified by the object to be written and the associated directory at each upward directory level, the first Find out the pre-set quota upper limit for the directory and the latest written total amount occupied by the written objects in the directory, and then analyze the distance to reach the quota of the directory on the basis of the latest written total amount in the directory The amount of allowed objects to continue to be written in the upper limit is regarded as the remaining allowed quota of the directory in this embodiment. Subsequently, it is determined by dividing the size between the specified write amount of the object to be written and the remaining allowed quota of the directory. Whether the directory can continue to write the object to be written to avoid excessive writing in the directory.

Exemplarily, since when the corresponding quota upper limit is set for a specified directory in advance according to the directory quota requirement, only the quota upper limit of some specified directories may be individually set, and the quota of other directories is not required. The write directory currently specified by the write object and the quota upper limit of each associated directory may be empty. Therefore, in this embodiment, the remaining permission quota of the directory is determined according to the quota upper limit of the directory and the latest total written amount. Including: if the quota upper limit of the directory is empty, it is determined that the remaining license quota of the directory has no upper limit; if the quota upper limit of the directory is not empty, the difference between the quota upper limit of the directory and the latest written total amount is taken as The remaining license quota for this directory.

Specifically, for the write directory currently specified by the object to be written and each directory in the associated directory at each upper directory level of the write directory, if the upper limit of the quota of the directory is empty, it means that the current quota for the directory is empty. The amount of object writing is not required, so it can be directly determined that the remaining license quota of the directory has no upper limit, that is, any amount of objects can be written at will; and if the quota upper limit of the directory is non-empty, it means that the objects in the directory are currently being written to. There are certain restrictions on the amount of input. At this time, the latest written total amount of the directory is analyzed, and the difference between the quota upper limit of the directory and the latest written total amount is used as the remaining license quota of the directory, so as to avoid the directory's total amount. The amount of written object data exceeds the quota upper limit of the directory; that is, when determining whether the specified write amount of the object to be written is less than the remaining permitted quota of the write directory and each associated directory, directly skip the write directory and For directories with an empty quota upper limit in each associated directory, only determine whether the specified write volume of the object to be written is less than the write directory and the remaining license quota in each directory with a non-empty quota upper limit in each associated directory.

S240, if the specified write amount of the object to be written is less than the remaining permission quota of the write directory and less than the remaining permission quota of the associated directory, write the object to be written into the write directory.

S250, update the latest written total amount of the written directory and the associated directory.

Optionally, after the specified write amount of the object to be written is less than the remaining permission quota of the write directory and less than the remaining permission quota of each associated directory, so that the object to be written is written into the write directory, the The latest written totals of the write directory and the associated directories under the directory level will increase accordingly, so it is necessary to update the latest written totals of the write directory and each associated directory found. For example, add the specified write amount of the object to be written on the basis of the write directory and the existing written total amount of each associated directory found, as the latest written total amount of the corresponding directory. quantity.

S260, if the specified write amount of the object to be written is greater than or equal to the remaining permission quota of the write directory, or greater than or equal to the remaining permission quota of the associated directory, prohibit writing the object to be written in the write directory.

In the technical solution provided by this embodiment, a corresponding upper limit of quota is set for the specified directory in advance, so as to limit the write directory specified by the object to be written and the remaining permission quota of the associated directory at the upper and lower directory levels of the write directory, It can effectively avoid excessive writing to a single directory by different objects. At the same time, when the specified write volume of the object to be written is less than the remaining permission quota of the write directory and less than the remaining permission quota of each associated directory, the to-be-written The input object is written to the write directory, so that the object to be written can uniformly meet the quota requirements of the specified write directory and each associated directory, preventing the occurrence of meeting the quota requirements of the write directory and exceeding the upper directory level. In the case of quota requirements of an associated directory, improve the adaptability of writing objects in different directories, and at the same time, after writing the object to be written into the writing directory, update the latest written directory and associated directory in time. The total amount of writing to ensure the accuracy of the remaining license quota of the written directory and associated directories, and to improve the adaptation accuracy of object writing.

Embodiment 3

FIG. 3A is a flowchart of a method for writing an object according to Embodiment 3 of the present invention, and FIG. 3B is a schematic schematic diagram of a principle of writing an object according to Embodiment 3 of the present invention. This embodiment is optimized on the basis of the above-mentioned embodiment. Specifically, as shown in FIG. 3B , in this embodiment, other processing procedures existing in the object writing process are explained in detail.

Optionally, as shown in FIG. 3A , this embodiment may include the following steps:

S310, according to the cascade state between different directories, generate a corresponding directory tree.

Optionally, when the CephFS system is initialized, the corresponding directory levels will be preset according to the writing requirements of different objects, and corresponding system directories will be created under different directory levels. At this time, as shown in Figure 3B, in order to ensure that each directory is located. The correlation between directory levels, the MDS server can determine the first-level directory in the overall scope by analyzing the cascading status between the various directories in the CephFS system, and the multi-level directory created under the first-level directory. A subdirectory is used as the second-level directory, and so on. According to the cascading state between different directories, the corresponding directory tree is generated, and the subsequent directory tree can be directly based on the cascade situation between the various directories in the directory tree. The write directory currently specified by the write object is written to the associated directory under the directory level at each upper level to ensure the comprehensiveness of the associated directory.

S320: Receive a write command of the object to be written.

Specifically, when the client performs a corresponding write operation in a certain directory of the CephFS system, a corresponding write command will be generated. The write command carries the write directory specified by the object to be written; the MDS server receives the After the write command, the object to be written specified by the write command and the write directory currently specified by the object to be written are first analyzed, so as to perform a corresponding object write operation.

S330: Find out, according to the directory tree, the associated directories of the write directory specified by the to-be-written object at each upper directory level.

S340, for each directory in the write directory and the associated directory, according to the specified number of write objects in the specified write amount of the object to be written and the number of remaining permitted write objects in the remaining permitted quota of the directory, the first The comparison result, and the second comparison result of the specified write memory amount in the specified write amount of the object to be written and the remaining allowable write memory amount in the remaining permitted quota of the directory, determine the specified amount of the object to be written Whether the amount of writes is less than the remaining license quota for this directory.

Optionally, when setting the corresponding quota upper limit for the specified directory in advance according to the directory quota requirement, you can set the quota of the specified directory in terms of the number of objects and the amount of memory occupied. In this case, before writing to the directory and writing the objects to be written , it is also necessary to judge whether the object to be written meets the quota requirements of the write directory and each associated directory from the two aspects of the number of objects and the amount of memory occupied. After going up to the associated directory under the directory level, as shown in FIG. 3B, for each directory in the write directory and each associated directory, first, according to the upper limit of the number of objects contained in the upper quota limit set under the directory and the written objects Total number, calculate the number of remaining permitted write objects in the remaining permitted quota of the directory, and calculate the remaining permission of the directory according to the upper limit of the amount of written memory and the total amount of written memory included in the upper quota limit set in the directory The remaining allowable write memory amount in the quota, and then determine the specified write object number and the specified write memory amount in the specified write amount of the object to be written, and determine the specified write object number of the to-be-written object and The first comparison result of the number of remaining permitted write objects in the directory, and the second comparison result of the specified write memory amount of the object to be written and the remaining permitted write memory amount of the directory, only when the object to be written The specified number of write objects in the directory is less than the number of remaining permitted write objects in the directory, and the specified write memory of the object to be written is less than the remaining permitted write memory of the directory, the specified write object of the object to be written can be determined The input amount is less than the remaining license quota of the directory, so as to realize the quota requirements of different directories in multiple dimensions.

S350, if the specified write amount of the to-be-written object is less than the remaining permitted quota of the write-in directory and less than the remaining permitted quota of the associated directory, write the to-be-written object into the write directory.

S360, if the specified write amount of the object to be written is greater than or equal to the remaining permission quota of the write directory, or greater than or equal to the remaining permission quota of the associated directory, prohibit writing the object to be written in the write directory.

The technical solution provided by this embodiment sets the upper limit of the quota of different directories from various aspects, realizes the quota requirements of different directories in multiple dimensions, and finds out the currently specified writing directory of the object to be written. After the directory is associated, the object to be written is written to the write directory only when the specified write amount of the object to be written is less than the remaining permission quota of the write directory and less than the remaining permission quota of each associated directory. , so that the object to be written can uniformly meet the quota requirements of the specified write directory and each associated directory, and prevent the situation that the quota requirements of the write directory are met but the quota requirements of an associated directory under the upward directory level are exceeded. , while limiting the remaining permission quota of the write directory and the associated directory, which can effectively avoid excessive writing to a single directory by different objects, and improve the adaptability of writing objects in different directories.
