Detailed Description
The core of the invention is to provide a maintenance method of the bus map of the distributed file system, which can improve the maintenance efficiency of the bus map; the other core of the invention is to provide a distributed file system managing device, equipment and a readable storage medium.
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The first embodiment is as follows:
referring to fig. 1, fig. 1 is a flowchart of a method for maintaining a distributed file system pool map according to this embodiment; the method mainly comprises the following steps:
step s 110: and when a pause map maintenance instruction is received, inquiring the current tree pause map data.
When a pause map maintenance instruction is received, it is indicated that the pause map structure of the system needs to be adjusted currently to adapt to different requirements, and current tree-shaped pause map data is immediately inquired, wherein related commands exist in the tree-shaped structure background of the distributed file system and can be inquired, and the process of acquiring the tree-shaped pause map data of the current system can refer to related technologies, which are not described herein again.
In addition, the background receiving of the pause map maintenance instruction can be realized by the way that the user clicks an adjustment pause map button on the front-end interface, and the like, which is not limited herein.
Step s 120: and carrying out visual editing processing on the tree-shaped pause map data to obtain a current pause map tree output to a display interface.
The visual editing process mainly includes a user editable process of performing the visual process and the visual shuffle map. The purpose of performing visualization processing on the tree-shaped pause map data is that a user can directly view the tree-shaped structure diagram of the pause map on a visual interface, so that the pause map structure of a system background can be conveniently viewed, and compared with the traditional method that the user needs to view complex pause map background data, the pause map structure viewing difficulty is greatly reduced. Compared with the traditional method that the user can directly edit and adjust the tree structure diagram of the pause map to realize the adjustment of the structure of the system pause map, the method has the advantages that the pause map is exported into a binary file and then compiled into a common file, and then the pause map maintenance process is directly modified by related technicians.
The processes of visualizing the background data and editing the background data by the user on the visualization interface can refer to the implementation manners in the related art, and the detailed implementation steps are not described herein, please refer to the related art.
Step s 130: and after receiving a dragging editing instruction for the current pause map tree, carrying out structure adjustment on the current pause map tree according to the dragging editing instruction to obtain an adjusted pause map tree.
The user sends a dragging editing instruction to the current grow map tree by dragging and editing the grow map tree in the GUI, and performs a corresponding editing operation to the file system tree structure after receiving the editing instruction, for example, when the user edits the file 11 in the file 1 to the file 2, that is, the file 11 is adjusted from the subordinate file of the file 1 to the subordinate file of the file 2, the user automatically adjusts the dependency relationship part of the file 11 in the current grow map tree after receiving the adjusting instruction, and the adjusted grow map tree can be obtained.
In this embodiment, the determination method of the adjusted grow map tree is not limited, for example, the grow map tree that remains unchanged and exceeds the threshold may be automatically determined as the adjusted grow map tree, or a user may click a button that completes adjustment after adjustment is completed, and the grow map tree in this state is used as the adjusted grow map tree. Preferably, when the adjustment completion instruction is received, the pause map tree of the current display interface is acquired, and the acquired pause map tree is used as the adjusted pause map tree, so that useless subsequent processing work can be avoided, and the maintenance efficiency is improved.
Step s 140: and determining the replacement tree-shaped grow map data according to the adjusted grow map tree.
After the pause map tree is adjusted, in order to ensure that the system can be identified and applied, the visual pause map structure tree needs to be converted into background identifiable pause map structure data again. The process of converting the visual bug map structure tree into the identifiable data of the background corresponds to the process of converting the identifiable bug map data of the background into the visual bug map structure tree in the above steps, and the implementation processes thereof can be referred to related technologies, and are not described herein again.
In this embodiment, a manner of determining to replace the tree-shaped grow map data according to the adjusted grow map tree is not limited, and preferably, a process of determining to replace the tree-shaped grow map data according to the adjusted grow map tree may specifically include the following steps:
1. taking the adjusted grow map tree as a replacement grow map tree;
2. and analyzing the replacement bus map tree to generate replacement tree bus map data.
The determining mode avoids the steps of determining the adjusting part and the like, directly conducts background analysis on the currently adjusted pause map tree and then conducts import, can simplify the step of determining and replacing pause map structure data for application scenes with more pause map structure adjustment and the like, and improves the processing efficiency.
Preferably, the replacement tree grow map data may also be determined with reference to the following steps:
1. carrying out difference comparison on the adjusted pause map tree and the current pause map tree, and determining a part to be adjusted of the current pause map tree;
2. and adjusting the current grow map data according to the part to be adjusted to obtain the replaced tree grow map data.
According to the method, the original pause map data are directly and correspondingly adjusted after the part to be adjusted is determined, the step of determining pause map data generation can be simplified for application scenes with less pause map structure adjustment and the like, and the processing efficiency is improved.
In this embodiment, only the two ways of determining replacement tree grow map data are described as an example, and the determination process of other replacement tree grow map data may refer to the description of this embodiment and will not be described herein again.
Step s 150: and importing the replacement tree grow map data into the system.
And leading the replacement tree grow map data to replace the current tree grow map data into the system so as to enable the adjusted grow map structure to take effect. The implementation manner of importing the replacement tree grow map data into the system may refer to related technologies, and is not described herein again.
While the foregoing description mainly describes the method for maintaining the scrub map in the background operation view, for the user view, one method for maintaining the scrub map can be referred to the following description:
a user clicks an interface to adjust a pause map button, a pause map tree in the cluster is automatically displayed on the interface, and pause map adjustment can be directly carried out in a mouse dragging mode;
the user performs operations such as dragging on a GUI (graphical user interface) for editing the pause map to adjust the pause map to a needed pause map structure, and the operations such as dragging are equivalent to editing the file system tree structure;
and after the user finishes the adjustment, clicking to determine, and automatically analyzing the interface until the adjusted pause map is imported into the cluster through the api interface, wherein the pause map is also successfully modified.
Therefore, compared with the traditional maintenance mode that the cluster crush map is exported into a binary file and then compiled into a common file and then the file is directly modified by related technical personnel, the maintenance mode with complexity is complex, the maintenance of the crush map can be realized only by adjusting the visual crush map tree structure diagram by dragging and the like, the whole maintenance process is simplified, the maintenance difficulty and complexity are greatly reduced, and the crush map modification by common users is facilitated.
Based on the introduction, the distributed file system managing map maintenance method disclosed by the embodiment of the invention carries out visual editing processing on the tree-shaped managing map data obtained by query and outputs the tree-shaped managing map data to the display interface when receiving a managing map maintenance instruction, and a user can directly view the tree-shaped structure diagram of the managing map on the display interface; when the user needs to carry out structural adjustment of the crush map, dragging, editing and adjusting can be directly carried out on the current crush map tree through the display interface, the whole process is simple and convenient to operate and easy to use, field operation is convenient for implementing personnel, tree-shaped crush map data can be automatically determined and replaced according to the adjusted crush map tree after the user is adjusted, the data are led into the system, and modification of the crush map is completed. The method integrates the manual process of modifying the pause map into the interface in a GUI mode, simplifies the process of modifying the pause map and improves the maintenance efficiency of the pause map.
Example two:
in the above embodiment, a manner of determining replacement tree-shaped grow map data according to the adjusted grow map tree is not limited, where a to-be-adjusted portion of the current grow map tree is first determined, and the current grow map data is adjusted according to the to-be-adjusted portion to determine that the replacement tree-shaped grow map data is applicable to multiple adjustment scenarios and is easy to adapt in each application scenario.
In order to reduce the adjustment workload as much as possible and ensure the determination efficiency of replacing the tree-shaped grow map data in different scenarios such as large-scale adjustment and fine structure adjustment, preferably, before adjusting the current grow map data according to the portion to be adjusted, the following determination process may be further performed:
judging whether the part to be adjusted reaches the structural data replacement standard or not;
then, adjusting the current credit map data according to the part to be adjusted specifically includes: when the part to be adjusted does not reach the structural data replacement standard, adjusting the current pause map data according to the part to be adjusted;
when the part to be adjusted reaches the structural data replacement standard, taking the adjusted pause map tree as a replacement pause map tree;
and analyzing the replacement bus map tree to obtain replacement tree bus map data.
The structural data replacement standard is not a preset standard for measuring the adjustment amount of structural data, when the structural data replacement standard exceeds the standard, the current adjustment scale of the bus map is indicated to be large, at the moment, the workload for adjusting the pair of original bus map data one by one aiming at each adjusting part is possibly large, the adjusting speed is also slow, and meanwhile, the structure of the bus map is disturbed to influence the normal operation of the system in the large rule adjustment, so that the efficiency of determining the bus map data is ensured aiming at the condition, and recognizable background data of the bus map can be directly regenerated to replace the current bus map data according to the currently determined adjusted bus map tree; and when the standard is not exceeded, indicating that the current adjustment scale of the pause map is smaller, if the workload of regenerating the recognizable data of the pause map background is possibly larger directly according to the currently determined adjusted pause map tree, correspondingly modifying and adjusting the generation speed of the pause map background data based on the original pause map data. Therefore, the overall maintenance efficiency can be improved by further determining the following judgment process before the current sink map data is adjusted according to the part to be adjusted, and meanwhile, the high availability of the adjusted sink map data is ensured.
In addition, in consideration of system security, in order to prevent unauthorized persons from arbitrarily modifying the structure of the housemap to affect normal operation of the system, before adjusting the current data of the housemap according to the portion to be adjusted, authorization verification may be further performed on the current maintenance behavior, and the following steps may be specifically referred to:
1. acquiring user information;
2. determining the maintenance authority of the current adjustment user according to the user information to obtain maintenance authority data;
3. judging whether the part to be adjusted contains a part exceeding the maintenance authority or not according to the maintenance authority data;
then, adjusting the current credit map data according to the part to be adjusted specifically includes: and when the part to be adjusted does not contain the part exceeding the maintenance authority, adjusting the current credit map data according to the part to be adjusted.
Setting corresponding pause map adjusting permission for each user in advance, for example, the user 1 cannot adjust the relative relation between the node A and the node B in the pause map, the user 2 cannot adjust the pause map structure at all, and the like, so as to limit the pause map adjusting behavior of the operator, and once the current pause map adjustment exceeds the corresponding permission, the current adjustment can be rejected.
In order to prompt the user when the user is not adjusting the pause map structure, so as to adjust the maintenance behavior of the current pause map structure in time, it is preferable that when the part to be adjusted includes a part exceeding the maintenance authority, prompt information for currently adjusting the exceeding authority be output. For example, a prompt message "you have no right to adjust the relative relationship between node a and node B" is output.
The method provided by the embodiment determines to replace tree-shaped grow map data, so that the grow map maintenance efficiency can be improved while the system safety is ensured, and the user experience is improved.
