Description

Technical Field

[0001] The present invention relates to the technical field of NAS resource residue cleaning, and in particular, to a method, device and storage medium for cleaning NAS storage resource residues. Background Art

[0002] NAS (Network Attached Storage) storage is usually designed directly for users, and can provide users with file-level user storage. Users can remotely access and perform data storage and retrieval services through protocols such as NFS, CIFS, and FTP.

[0003] When a user uses NAS storage, the server itself usually automatically creates the resources required by the file system in the background and automatically performs preprocessing to provide services for the user. In addition to the file system, other services related to NAS, such as NAS snapshots and NAS disaster recovery, can also complete the resource creation work without the user's awareness. Since NAS storage directly provides file-level storage services for users, users' perception of background resources is not intuitive enough. When the system encounters an exception or other reasons (such as system power failure, storage disk being unplugged, etc.) that cause the NAS service to be interrupted during the service provision process, various types of resource residues are likely to be generated, and users may not be aware of it. As the running time of the NAS storage device accumulates, more and more accumulated resource residues are generated. The residual resources not only occupy the resource specifications of the system, affect user usage, but also may reduce the system performance, affect the creation of other resources, and cause the NAS storage to be unable to provide services normally, resulting in losses. Summary of the Invention

[0004] In order to solve the above technical problems or at least partially solve the above technical problems, the present invention provides a method, device and storage medium for cleaning NAS storage resource residues.

[0005] In a first aspect, the present invention provides a method for cleaning NAS storage resource residues, including: constructing a NAS resource database for maintaining resource information of NAS resources, where the resource information includes: the resource name and resource type of the NAS resources;

[0006] During relatively idle business hours, periodically compare and analyze the NAS resources in a non-creating or non-deleting state and the resource information status in the NAS resource database according to the residual resource identification scheme to determine whether the NAS resources are residual; when it is found that all subtype resources related to the NAS resources are residual and there is no corresponding resource information in the NAS resource database, identify them as resource residues and record them in the resource residue list; when it is found that there is resource information in the NAS resource database but the NAS resource cannot be found, record it in the database residue list; when it is found that all subtype resources of the NAS resource exist and the status is normal, but there is no corresponding resource information in the NAS resource database, record it in the database update list; perform corresponding operations according to the data in the resource residue list, the database residue list, and the database update list to clean up the residual resources and update the NAS resource database.

[0007] Furthermore, configure status attributes for the NAS resources, and the status attributes include the deleting state and the creating state; during the creation process of the NAS resource, before the creation of the last subtype resource involved in the NAS resource is completed, the NAS resource is in the creating state; during the deletion process of the NAS resource, before the deletion of the last subtype resource involved in the NAS resource is completed, the NAS resource is in the deleting state.

[0008] Furthermore, when deleting the NAS resource, starting from the data of the first subtype resource of the deleted NAS resource, clear the resource information related to all subtype resources involved in the NAS resource from the NAS resource database.

[0009] Furthermore, when creating the NAS resource, after all subtype resources involved in the NAS resource are created, verify the integrity of the NAS resource. After verification, record the corresponding resource information in the NAS resource database.

[0010] Furthermore, comparing and analyzing the NAS resources in a non-creating or non-deleting state and the resource information status in the NAS resource database according to the residual resource identification scheme to determine whether there are residues includes: setting different integrity verification schemes according to the different types of NAS resources and the different subtype resources required by different types of NAS resources to judge the residual resources. The different types of NAS resources include: NAS resources of the NAS file system type, NAS shared resources, NAS user resources, and NAS snapshots.

[0011] Further, comparing and analyzing the NAS resources in a non-creating state or a non-deleting state and the resource information status in the NAS resource database according to the residual resource identification scheme to determine whether there are residues includes: when subtype resources can be found in the NAS resource database, but there is no record of the NAS resources in the NAS resource database, after the deletion process updates the NAS resource database, the deletion process of the subtype resources of the NAS resources is not completed, or during the creation of the NAS resources, the creation process of the subtype resources of the NAS resources is not completed, and as a result, the creation process is interrupted and the database is not updated. The queried subtype resources are identified as residual resources.

[0012] Further, perform corresponding operations according to the data in the resource residue list, the database residue list, and the database update list, and clean the residual resources and update the NAS resource database, including:

[0013] Delete the corresponding residual resources in the system according to the content of each item in the resource residue list; delete the corresponding resource information in the NAS resource database according to the content of each item in the database residue list; add the corresponding resource information to the NAS resource database according to the content of each item in the database update list.

[0014] Further, record the NAS resources in a creating state or a deleting state that have not been detected for residues through the undetected list; monitor the creation or deletion status of the NAS resources in the undetected list, and when the creation or deletion is completed, perform residue detection on the NAS resources that have completed creation or deletion.

[0026] To make the objectives, 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 accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part rather than all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0027] It should be noted that, in this document, the terms "include", "comprise" or any other variant thereof are intended to cover a non-exclusive inclusion, such that a process, method, article or device comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article or device. Without further limitation, an element defined by the phrase "comprising a..." does not exclude the presence of additional identical elements in the process, method, article or device comprising the element.

[0028] Embodiment 1

[0029] Refer to Figure 1 As shown, the present invention provides a method for cleaning NAS storage resource residues, which includes:

[0030] S100. Build a NAS resource database for maintaining the resource information of NAS resources, where the resource information includes the resource name and resource type of the NAS resources. During the specific implementation process, a modification interface for the NAS resource database is reserved, and the design modification of the NAS resource database can be made according to requirements during later maintenance.

[0031] Refer to Figure 2 As shown, when creating a NAS resource, the resource information of the NAS resource for verifying integrity is maintained in the NAS resource database:

[0032] S101. All the sub-type resources involved in the NAS resource are created. During the creation of the NAS resource, the creation of several sub-type resources is involved. For example, a NAS resource involves three sub-type resources: a file system volume, a volume mapping relationship, and a file system resource. Only when all three sub-type resources are created can the NAS resource be created.

[0033] S102. Verify the integrity of the created NAS resource. If the verification is complete, execute S103. Specifically, when all subtype resources are created, judge the integrity of the created NAS resource by checking the existence and status of the subtype resources involved in the NAS resource. For example, for a NAS resource involving three subtype resources: file system volume, volume mapping relationship, and file system resource, the NAS resource is considered complete only when all three subtype resources of file system volume, volume mapping relationship, and file system resource exist and are in normal status.

[0034] S103. Automatically record the corresponding resource information of the NAS resource into the NAS resource database.

[0035] If the created NAS resource is verified to be complete, record the resource information of the NAS resource into the NAS database.

[0036] When deleting a NAS resource, delete the corresponding resource information of the NAS resource in the NAS resource database: When deleting a NAS resource, start from the data of the first subtype resource of the deleted NAS resource, that is, automatically clear all the resource information related to the subtype resources involved in the NAS resource from the NAS resource database.

[0037] S200. At a time when the business is relatively idle, periodically compare and analyze the NAS resources in a non-creating or non-deleting state and the resource information status in the NAS resource database according to the residual resource identification scheme to determine whether there is a residue.

[0038] In the specific implementation process, since traversing the NAS resources in the system for residue detection takes up some CPU resources, and the residue generation rate itself is a small probability event, in order to reduce the CPU occupancy rate during the residue detection and cleaning process, it is set to execute at 3:00 am every day when the business is relatively idle, and execute once a day to reduce the impact on the normal business of the NAS storage and avoid excessive accumulation of resource residues. A feasible method for timing the residue detection uses the crontab timing command.

[0039] In the specific implementation process, refer to Figure 3 As shown, comparing and analyzing the NAS resources in a non-creating or non-deleting state and the resource information status in the NAS resource database according to the residual resource identification scheme to determine whether there is a residue includes:

[0040] S201. When performing NAS resource residue detection, obtain the status attributes of NAS resources. In the specific implementation process, configure status attributes for NAS resources. The status attributes include the deleting status and the creating status. During the creation process of a NAS resource, before the last subtype resource involved in the NAS resource is created, the NAS resource is in the creating status. During the deletion process of a NAS resource, before the last subtype resource involved in the NAS resource is deleted, the NAS resource is in the deleting status.

[0041] S202. After excluding NAS resources in the deleting status and the creating status according to the status attributes, perform residue detection on the remaining NAS resources. For NAS resources in the deleting status or the creating status, do not perform residue detection to avoid abnormal situations caused by repeatedly deleting resources that are in the process of being deleted or deleting NAS resources that are in the process of being created.

[0042] Furthermore, record NAS resources in the creating status or the deleting status that have not undergone residue detection through an undetected list; monitor the creation or deletion status of NAS resources in the undetected list, and when the creation or deletion is completed, perform residue detection on the NAS resources that have completed creation or deletion. Comparing and analyzing the resource information status of NAS resources that are not in the creating status or the deleting status and the resources in the NAS resource database according to the residue resource identification scheme to determine whether it is a residue includes:

[0043] S203. Use an integrity verification scheme to judge residue resources for different types of NAS resources. Specifically, according to the different types of NAS resources and the different subtype resources required by different types of NAS resources, set different integrity verification schemes to judge residue resources. The different types of NAS resources include: NAS resources of the NAS file system type, NAS shared resources, NAS user resources, and NAS snapshots. For example, for NAS resources of the NAS file system type, the included subtype resources include file system volumes, volume mapping relationships, and file system resources. Only when all three subtype resources are working properly and there are corresponding resource information records in the NAS database, the NAS resource is non-defective; otherwise, judge the NAS resource as a residue resource. Furthermore, when the subtype resources of a NAS resource can be found in the NAS resource database but there is no record of the NAS resource, after the deletion process updates the NAS resource database, the deletion process of the subtype resources of the NAS resource is not completed, or during the creation process of the NAS resource, the creation process of the subtype resources of the NAS resource is not completed and the creation process of the NAS resource is interrupted without updating the database, the queried subtype resources are identified as residue resources.

[0044] S300. Statistically generate a resource residue list, a database residue list, and a database update list for controlling residue cleanup and NAS resource database updates based on the residue and resource information:

[0045] When it is found that residues exist for all subtype resources related to NAS resources and corresponding resource information does not exist in the NAS resource database, they are identified as resource residues and included in the resource residue list.

[0046] When it is found that resource information exists in the NAS resource database but the NAS resource cannot be found, it is included in the database residue list.

[0047] When it is found that all subtype resources of the NAS resource exist and the status is normal, but they do not exist in the NAS resource database, they are included in the database update list.

[0048] S400. Perform corresponding operations based on the data in the resource residue list, the database residue list, and the database update list to clean up the residues and update the NAS resource database. In the specific implementation process, performing corresponding operations based on the data in the resource residue list, the database residue list, and the database update list to clean up the residual resources and update the NAS resource database includes:

[0049] Delete the corresponding residual resources in the system according to the content of each item in the resource residue list; delete the corresponding resource information in the NAS resource database according to the content of each item in the database residue list; add the corresponding resource information to the NAS resource database according to the content of each item in the database update list.

[0050] Embodiment 2
