Detailed Description
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 only a part of the embodiments of the present invention, and not all of the embodiments. 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.
As will be appreciated by one skilled in the art, embodiments of the present invention may be embodied as a system, apparatus, method or computer program product. Accordingly, the present disclosure may be embodied in the form of: entirely hardware, entirely software (including firmware, resident software, micro-code, etc.), or a combination of hardware and software.
Before describing embodiments of the present invention, terms of art to which embodiments of the present invention relate will be described.
NFS: network file systems (Network file systems) allow users to access files on remote hosts in the same way as any local file is accessed. This file access is completely transparent to the client and can work on a variety of servers and a variety of host architectures.
NAS: network Attached Storage (Network Attached Storage), a common technical scheme of a Network file system in a private cloud technology stack, is generally to perform Storage division on an NAS Storage server, create a Storage volume, and then provide services to the outside through a head IP Network.
Storage volume: the physical storage device may be partitioned into logical storage volumes for use by different users, and one storage device may create multiple storage volumes.
Next, the inventor introduces the idea of finding technical problems and proposing a reclamation method for a network file system.
In the private cloud testing environment, the use of NFS is very common, typically provided by centralized NAS storage. Storage volumes may be created on the NAS storage, an NFS is established on each storage volume, and the NFS determines which servers may access the NFS by configuring export rules. The test environment is characterized in that the change is frequent, the server can frequently allocate and recover the NFS, generally, when the NFS is recovered, a server administrator should check whether the server has the NFS which is not mounted, if so, the NAS storage administrator is notified to recover the access right of the server to the NFS, if the whole NFS is determined not to be used, the NAS storage administrator is notified to recover the NFS resources, and the corresponding configuration information and the storage volume are deleted.
However, in a test environment, it is often the case that a server forgets to notify a NAS administrator to recover the NFS during recovery, or the server itself loses the mount information of the NFS, which may cause that NFS resources that should be recovered cannot be recovered, and cause resource waste just like memory leakage. At present, no technical solution is provided in the industry for the situation, and the normalization of the recovery process is mainly ensured by means of management, but the regulatory process is easily broken by the requirements on high-frequency change and high timeliness of the test environment. The prior art proposes a method for calculating the real capacity of the NAS file system, which achieves the purpose of saving resources by adjusting the allocated capacity of the storage volume, but there is no way to distinguish the NFS that is "leaked" as described above.
In order to solve the technical problems of low recovery efficiency and resource waste caused by the fact that NFS resources are recovered through manual inspection and notification in the prior art, an embodiment of the present invention provides a recovery method for a network file system, which is used for improving the recovery efficiency of NFS resources and avoiding resource waste, fig. 1 is a schematic diagram of a flow of the recovery method for the network file system in the embodiment of the present invention, and as shown in fig. 1, the method includes:
step 101: obtaining configuration information of a network file system NFS, wherein the configuration information comprises: an IP address where NFS can be accessed;
step 102: sending a detection request to a server corresponding to the IP address, and judging whether a server which does not mount the NFS exists or not;
step 103: if the server without the NFS is installed, deleting the IP address corresponding to the server without the NFS from the configuration information of the NFS;
step 104: when the configuration information of the NFS does not include any IP address that can access the NFS, the NFS is placed in the recycle bin.
As shown in fig. 1, an embodiment of the present invention is implemented by: obtaining configuration information of a network file system NFS, wherein the configuration information comprises: an IP address where NFS can be accessed; sending a detection request to a server corresponding to the IP address, and judging whether a server which does not mount the NFS exists or not; if the server without the NFS is installed, deleting the IP address corresponding to the server without the NFS from the configuration information of the NFS; when the configuration information of the NFS does not contain any IP address capable of accessing the NFS, the NFS is placed into the recycle bin, the detection request is sent to the server corresponding to the IP address in the configuration information of the NFS, the automatic detection of the mounting condition of the NFS is realized, the IP address without mounting the NFS can be automatically deleted from the configuration information of the NFS, the NFS which does not need to be accessed is automatically recycled, the efficiency of recycling NFS resources is improved, and the waste of resources is effectively avoided.
In one embodiment, the NFS stores NAS storage over a network attached storage;
the NAS comprises a plurality of storage volumes, and each storage volume corresponds to one NFS.
In one embodiment, the method further comprises:
acquiring configuration information, identification information and capacity information of a plurality of NFSs through an NAS management platform;
and establishing an NFS, deleting the NFS or modifying the configuration information of the NFS through the NAS management platform.
In specific implementation, the embodiment of the present invention is based on an existing NAS management platform, where the NAS includes a plurality of storage volumes, each storage volume corresponds to one NFS, and in step 101, the NAS management platform may collect information of all NFSs, including: configuration information, identification information and capacity information, wherein the configuration information comprises: the IP address of the NFS can be accessed, and operations such as new creation, deletion and configuration information modification (IP address addition or deletion) of the NFS can be executed, so that the overall process management and control of the NFS are realized.
In one embodiment, the issuing of the probe request to the IP address in step 102 includes:
and sending the detection requests to the servers corresponding to the IP addresses in batches through the batch processing platform.
In specific implementation, fig. 2 is a schematic diagram of an overall NFS recycling flow in the embodiment of the present invention, as shown in fig. 2, since the NAS management platform cannot grasp the actual use condition of the NFS, a manner of actively initiating a probe request is adopted in step 102, first, according to the configuration information of the NFS recorded on the NAS management platform obtained in step 101, the IP addresses of all servers included in the configuration information of each NFS are checked, then, a probe request is sent to the servers corresponding to the IP addresses in batches at regular time through the batch operation platform, whether the servers mount the corresponding NFS is checked, in step 103, if there is a server that does not mount the NFS, the IP address corresponding to the server that does not mount the NFS is deleted from the configuration information of the NFS, if there is no server that does not mount the NFS, the configuration information of the NFS is not modified, and finally, in step 104, when there is no IP address included in the configuration information of one NFS, indicating that any server cannot access the NFS, placing the NFS in a recycle bin, and when configuration information of one NFS includes at least one IP address, retaining the NFS, which may be performed in a timed loop.
Fig. 3 is a schematic diagram of a recycling step in an embodiment of the present invention, as shown in fig. 3, in an embodiment, after placing the NFS into the recycling bin, the method further includes:
step 301: and if the access request of the NFS is not received within the preset time length, deleting the NFS.
As shown in fig. 3, in an embodiment, after placing the NFS in the recycle bin, the method further includes:
step 302: if the access authority request of the NFS is received within the preset duration, the NFS is moved out of the recycle bin;
step 303: and adding the IP address corresponding to the access authority request into the configuration information of the NFS.
In particular implementation, the probe initiated by the NAS management platform is not completely accurate, for example: the server is just restarted, so that the NFS is not automatically mounted, or the NFS needs to be temporarily uninstalled for some tests, if the server which is not mounted with the NFS is checked each time, the server goes to check and confirm with a server administrator, large labor cost and time cost are caused, but if the NFS is directly deleted, once the NFS is deleted by mistake, data cannot be recovered, and the result is unacceptable. Fig. 4 is a schematic diagram of an overall flow of a recycle bin in an embodiment of the present invention, as shown in fig. 4, in the embodiment of the present invention, when an NFS does not have any server to access, the NFS is placed in the recycle bin, after the NFS enters the recycle bin, a waiting duration may be preset, if an access request of the NFS is not received within the preset duration, the NFS may be considered to be no longer used, and may be deleted, if an access permission request of the NFS is received within the preset duration, which indicates that a server needs to continuously mount the NFS, an IP address corresponding to the access permission request may be added to configuration information of the NFS, so that an IP address corresponding to the access permission request may access the NFS, and the NFS is moved out of the recycle bin, which may prevent the NFS from being deleted mistakenly, and may ensure data security.
In the embodiment of the present invention, the functional logic for sending the probe request and the recycle bin mechanism may be implemented by java, python, C #, or other languages, and the present invention is not limited thereto, and in addition, the NAS management platform and the batch job platform may also be implemented by other platforms, and only the necessary functions need to be satisfied and the interfaces are opened, and the present invention is not limited thereto.
In one embodiment, the method further comprises: acquiring identification information and capacity information of the NFS;
placing the NFS into the recycle bin further comprises:
the identification information and capacity information of the NFS, and the time of entry into the recycle bin are stored.
In specific implementation, when the NFS enters the recycle bin, the related information of the NFS may also be stored, including: the identification information and the capacity information of the NFS and the time information of entering the recycle bin can record the recycling operation, so that the later backtracking is facilitated, and the data safety is further ensured.
It should be noted that while the operations of the method of the present invention are depicted in the drawings in a particular order, this does not require or imply that the operations must be performed in this particular order, or that all of the illustrated operations must be performed, to achieve desirable results. Additionally or alternatively, certain steps may be omitted, multiple steps combined into one step execution, and/or one step broken down into multiple step executions.
