Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of computer, in particular to a space capacity query method, device, equipment and medium. BACKGROUND

[0002] Currently, after a storage end establishes a file system, a specific directory on the file system is exported as an NFS (Network File System) shared, an NFSv4 service is provided externally, and a client is mounted and accessed on a client supporting the NFSv4.

[0003] In a multi-user access scenario, in order to facilitate the management of the file system storage space, an administrator usually configures different capacity quotas for different users and user groups. However, after the client mounts the NFSv4 shared using its own username on the client, the available capacity and the total capacity seen by the client through the df (disk free) command are still the available capacity and the total capacity of the file system, not the available capacity and the total capacity of the user, which can mislead the client and cause unnecessary errors.

[0004] In summary, how to query the total capacity and the available capacity of the user is a problem to be solved at present. SUMMARY

[0005] Therefore, the purpose of the present application is to provide a space capacity query method, device, equipment and medium, which can obtain the target total capacity and the target available capacity corresponding to a target user. The specific scheme is as follows:

[0017] Optionally, the obtaining the target available capacity of the target user according to the target total capacity and the used capacity of the target user comprises:

[0018] A target value is calculated by subtracting the used capacity of the target user from the target total capacity;

[0019] If the target value is positive, the target value is taken as the target available capacity of the target user;

[0020] If the target value is negative, the value zero is taken as the target available capacity.

[0021] Optionally, the determining the target user group in which the target user is located based on the preset capacity query logic and querying the user capacity quota and the used capacity of the target user and the user group capacity quota of the target user group comprises:

[0022] Based on the preset capacity query logic, the target user group in which the target user is located is determined according to the user information of the target user, and then the user group information of the target user group is queried;

[0023] query the user capacity quota and the user used capacity corresponding to the target user and the user group capacity quota corresponding to the target user group based on the user information and the user group information.

[0024] Optionally, after obtaining the target request sent by the target user through the client, the target user group in which the target user is located is determined based on preset capacity query logic, and the user capacity quota and the user used capacity corresponding to the target user and the user group capacity quota corresponding to the target user group are queried, including:

[0025] After obtaining the target request sent by the target user through the client, it is detected whether the field value of the target field is set to the numerical value 1.

It can be seen that, the preset capacity query logic is newly added to control the query of the user capacity quota corresponding to the target user, the user used capacity and the user group capacity quota corresponding to the target user group, so as to obtain the target total capacity and the target available capacity corresponding to the target user according to the user capacity quota, the user group capacity quota, the system total capacity and the user used capacity. Therefore, the target total capacity and the target available capacity corresponding to the target user can be sent to the client. BRIEF DESCRIPTION OF DRAWINGS

[0040] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments only constitute a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0041] After the current client mounts the NFSv4 share with own username on the client side, the available capacity and total capacity seen by the df (disk free) command are still the available capacity and total capacity of the file system, not the available capacity and total capacity of the user, which will mislead the client and cause unnecessary errors.

[0042] To overcome the above problems, the application provides a space capacity query scheme, which can obtain target total capacity and target available capacity corresponding to a target user.

[0043] Referring to Figure 1 As shown in the figure, the embodiment of the application discloses a space capacity query method applied to a network file system, which comprises the following steps:

[0044] Step S11: After obtaining the target request sent by the target user through the client, the target user group in which the target user is located is determined based on a preset capacity query logic, and the user capacity quota and user used capacity corresponding to the target user and the user group capacity quota corresponding to the target user group are queried.

[0045] In the embodiment of the application, the client views the space capacity information through the df (disk free) command, the target request exists in the target message sent by the target user to the client, the target request is the command word GETATTR, at this time, the client sends the command word to the local, and also needs to set the field values of the FATTR4_SPACE_AVAIL and FATTR4_SPACE_TOTAL target fields in the message to 1.

[0046] In the embodiment of the application, the preset capacity query logic can be referred to as a quota processing logic.

[0047] It should be pointed out that after obtaining the target request sent by the target user through the client, it is detected whether the field value of the target field is set to the numerical value 1; if the field value of the target field is set to the numerical value 1, the target user group in which the target user is located is determined based on the preset capacity query logic, and the user capacity quota and user used capacity corresponding to the target user and the user group capacity quota corresponding to the target user group are queried. It should be pointed out that the quota information configured on the file system is usually saved by the file system itself, which includes the quota information of the specified user and the capacity information already used by the user, and the file system will provide a query interface. It should be pointed out that if the field value of the target field is not set to the numerical value 1, the process of directly querying the capacity information (total capacity and available capacity) of the file system is executed, and then returned to the client.

[0048] It should be noted that the user capacity quota and the user group capacity quota are pre-allocated by an administrator, and the size relationship between the user capacity quota, the user group capacity quota and the system total capacity can not be specifically limited. When the administrator does not allocate the user capacity quota and the user group capacity quota for the target user and the target user group, the system total capacity is used as the user capacity quota and the user group capacity quota by default.

[0049] In the embodiment of the present application, the user information (uid) of the target user and the user group information (gid) of the target user group are required to query the user capacity quota and the used capacity of the target user and the user group capacity quota of the target user group. Therefore, first, the preset capacity query logic is based on, and the target user group in which the target user is located is determined according to the user information of the target user, and then the user group information of the target user group is queried. The user capacity quota (quota_usr) and the used capacity (quota_used_by_user) of the target user and the user group capacity quota (quota_group) of the target user group are queried based on the user information and the user group information. It should be noted that the user capacity quota, the used capacity and the user group capacity quota of the target user are respectively queried by the user information of the target user and the user group information of the target user group.

[0050] It should be noted that the query interface provided by the network file system is used to query the user capacity quota and the used capacity of the target user and the user group capacity quota of the target user group through the sysctl command. It should be noted that the sysctl is used to display all system parameters or load system parameters from a specified file, and in addition, the interface for querying the user capacity quota and the used capacity of the target user and the user group capacity quota of the target user group is provided by the network file system.

[0051] Step S12: Query the system total capacity corresponding to the network file system based on the preset interface provided by the network file system.

[0052] In the embodiment of the present application, the process of querying the total capacity information (fs_total) of the original direct file system is performed. It should be noted that the capacity information queried based on the preset interface provided by the network file system includes not only the total capacity information of the file system, but also the current available capacity (fs_ava) and the current used capacity (fs_used) of the file system. However, the current available capacity (fs_ava) and the current used capacity (fs_used) of the file system are not used in the process of obtaining the target available capacity and the target total capacity of the present application.

[0053] Step S13: obtaining the target total capacity and the target available capacity corresponding to the target user according to the user capacity quota, the user group capacity quota, the system total capacity and the user used capacity.

[0054] In the embodiment of the present application, the target total capacity and the target available capacity corresponding to the target user are obtained according to the user capacity quota, the user group capacity quota and the user used capacity obtained by the preset capacity query logic, and the system total capacity obtained by the original logic.

[0055] Step S14: sending the target total capacity and the target available capacity to the client.

[0056] In the embodiment of the present application, after obtaining the target total capacity and the target available capacity corresponding to the target user, the target total capacity and the target available capacity are sent to the client, instead of sending the local system total capacity and the system available capacity, so as to prevent misleading the client and the client application and causing unnecessary errors.

[0057] It should be noted that when the target request in the target message sent by the client is obtained, and the task in the target message is to query the capacity related information, the preset quota query logic is added to query the target total capacity and the target available capacity corresponding to the target user, and the target total capacity and the target available capacity are sent to the client. In the original method, when the available capacity and the total capacity of the mounted directory are queried, the system total capacity and the system available capacity are queried.

[0058] It can be seen that, after obtaining the target request sent by the target user through the client, the target user group in which the target user is located is determined based on preset capacity query logic, and the user capacity quota corresponding to the target user, the user used capacity and the user group capacity quota corresponding to the target user group are queried. The system total capacity corresponding to the network file system is queried based on the preset interface provided by the network file system. The target total capacity and the target available capacity corresponding to the target user are obtained according to the user capacity quota, the user group capacity quota, the system total capacity and the user used capacity. The target total capacity and the target available capacity are sent to the client. It can be seen that, the preset capacity query logic is newly added in the application to control the query of the user capacity quota corresponding to the target user, the user used capacity and the user group capacity quota corresponding to the target user group, so as to obtain the target total capacity and the target available capacity corresponding to the target user according to the user capacity quota, the user group capacity quota, the system total capacity and the user used capacity. Therefore, the target total capacity and the target available capacity corresponding to the target user can be sent to the client.

[0059] Referring to Figure 2 As shown in the drawings, the embodiment of the application discloses a specific space capacity query method, applied to a network file system, the method comprises:

[0060] Step S21: After obtaining the target request sent by the target user through the client, the target user group in which the target user is located is determined based on preset capacity query logic, and the user capacity quota corresponding to the target user, the user used capacity and the user group capacity quota corresponding to the target user group are queried.

[0061] In the embodiment of the application, the client views the space capacity information through the df command, the target request exists in the target message sent by the target user to the client, the target request is the command word GETATTR, at this time, the client sends the command word to the local, and also needs to set the field values of the FATTR4_SPACE_AVAIL and FATTR4_SPACE_TOTAL target fields in the message to 1.

[0062] In the embodiment of the application, the preset capacity query logic can be called quota processing logic.

[0063] It is to be noted that after obtaining the target request sent by the target user through the client, it is detected whether the field value of the target field is set to the numerical value 1; if the field value of the target field is set to the numerical value 1, the target user group in which the target user is located is determined based on the preset capacity query logic, and the user capacity quota corresponding to the target user, the user used capacity and the user group capacity quota corresponding to the target user group are queried. It is to be noted that the quota information configured on the file system is usually saved by the file system itself, wherein there is quota information of a specified user and capacity information already used by the user, and the file system provides a query interface. It is to be noted that if the field value of the target field is not set to the numerical value 1, the process of returning the capacity information (total capacity and available capacity) of the file system to the client after directly querying the capacity information of the file system is performed.

[0064] It is to be noted that the user capacity quota and the user group capacity quota are pre-allocated by an administrator, and the size relationship of the user capacity quota, the user group capacity quota and the system total capacity can not be specifically limited, and when the administrator does not allocate the user capacity quota and the user group capacity quota, the system total capacity is used as the user capacity quota and the user group capacity quota by default.

[0065] In the embodiment of the application, the user information (uid) of the target user and the user group information (gid) of the target user group are required to query the user capacity quota corresponding to the target user, the user used capacity and the user group capacity quota corresponding to the target user group, therefore, first, the target user group in which the target user is located is determined based on the preset capacity query logic and according to the user information of the target user, and then the user group information of the target user group is queried; the user capacity quota (quota_usr) corresponding to the target user, the user used capacity (quota_used_by_user) and the user group capacity quota (quota_group) corresponding to the target user group are queried based on the user information and the user group information. It is to be noted that the user information of the target user and the user group information of the target user group are used to respectively query the user capacity quota, the user used capacity and the user group capacity quota of the target user by the application.

[0066] It is to be noted that the user information of the target user and the user group information of the target user group are used to respectively query the user capacity quota, the user used capacity and the user group capacity quota of the target user by the application. It is to be noted that the sysctl is used to display all system parameters or load system parameters from a specified file, and in addition, the interface for querying the user capacity quota corresponding to the target user, the user used capacity and the user group capacity quota corresponding to the target user group is provided by the network file system.

[0067] Step S22: querying the total capacity of the network file system based on the preset interface provided by the network file system.

[0068] In the embodiment of the present application, the process of querying the total capacity information (fs_total) of the original file system is executed. It should be noted that the capacity information queried based on the preset interface provided by the network file system includes not only the total capacity information of the file system, but also the current available capacity (fs_ava) and the current used capacity (fs_used) of the file system. However, the current available capacity (fs_ava) and the current used capacity (fs_used) of the file system are not used in the process of obtaining the target available capacity and the target total capacity of the present application.

[0069] Step S23: obtaining the target total capacity corresponding to the target user according to the user capacity quota, the user group capacity quota and the total capacity of the system, and obtaining the target available capacity corresponding to the target user according to the target total capacity and the used capacity of the user.

[0070] In the embodiment of the present application, the specific process of obtaining the target total capacity corresponding to the target user according to the user capacity quota, the user group capacity quota and the total capacity of the system is as follows: selecting the minimum capacity among the user capacity quota, the user group capacity quota and the total capacity of the system as the target total capacity corresponding to the target user, for example, total = min (quota_usr, quota_group, fs_total), wherein total represents the target total capacity, and min represents the minimum value.

[0071] It should be noted that the target total capacity corresponding to the target user is jointly affected by the user capacity quota, the user group capacity quota and the total capacity of the system, and is the minimum value among the user capacity quota, the user group capacity quota and the total capacity of the system. For example, when the system capacity quota is greater than the user capacity quota, and the user capacity quota is greater than the user group capacity quota, the size of the target total capacity corresponding to the target user is the size of the user group capacity quota; when the user group capacity quota is greater than the user capacity quota, and the user capacity quota is greater than the total capacity of the system, the size of the target total capacity corresponding to the target user is the size of the total capacity of the system.

[0072] In the embodiment of the present application, the specific process of obtaining the target available capacity corresponding to the target user according to the target total capacity and the user used capacity is: calculating a target value by subtracting the user used capacity from the target total capacity; if the target value is positive, taking the target value as the target available capacity corresponding to the target user; if the target value is negative, taking the value zero as the target available capacity. For example, max(0, total-quota_used_by_user); wherein, max represents taking the maximum value. It should be noted that there is a case that the target available capacity of the target user is less than the user used capacity of the target user.

[0073] In an embodiment, when no quota is allocated for the target user and the target user group, taking the system total capacity as the user group capacity quota and the user capacity quota, in this case, the space capacity used by the target user is the first capacity (user used capacity), then allocating quota for the target user and the target user group, determining the target total capacity according to the quota allocated for the target user and the target user group and the system total capacity, if the quota allocated for the target user is less than the system total capacity, then the target total capacity is equal to the quota allocated for the target user, when the allocated quota is less than the first capacity (user used capacity), the calculated target value is negative, and the value zero is taken as the target available capacity.

[0074] Step S24: sending the target total capacity and the target available capacity to the client.

[0075] In the embodiment of the present application, after obtaining the target total capacity and the target available capacity corresponding to the target user, the target total capacity and the target available capacity are sent to the client, instead of sending the local system total capacity and the system available capacity, so as to prevent misleading the client and the client application and causing unnecessary errors, and improve the ease of use of the storage system.

[0076] It should be noted that when the target request in the target message sent by the client is obtained, and the task in the target message is to query the capacity related information, the preset quota query logic is added, so as to query the target total capacity and the target available capacity corresponding to the target user, and to send the target total capacity and the target available capacity to the client. In the original method, when the available capacity and the total capacity of the mounted directory are queried, the system total capacity and the system available capacity are queried.

[0077] It can be seen that, after obtaining the target request sent by the target user through the client, the preset capacity query logic is used to determine the target user group in which the target user is located, and the user capacity quota corresponding to the target user, the user used capacity, and the user group capacity quota corresponding to the target user group are queried. The system total capacity corresponding to the network file system is queried based on the preset interface provided by the network file system. The target total capacity corresponding to the target user is obtained according to the user capacity quota, the user group capacity quota, and the system total capacity, and the target available capacity corresponding to the target user is obtained according to the target total capacity and the user used capacity. The target total capacity and the target available capacity are sent to the client. It can be seen that, the preset capacity query logic is newly added to control the query of the user capacity quota corresponding to the target user, the user used capacity, and the user group capacity quota corresponding to the target user group, so as to obtain the target total capacity and the target available capacity corresponding to the target user according to the user capacity quota, the user group capacity quota, the system total capacity, and the user used capacity. Therefore, the target total capacity and the target available capacity corresponding to the target user can be sent to the client.

[0078] Referring to Figure 3 It is shown that the embodiment of the application discloses a space capacity query device applied to a network file system, comprising:

[0079] The first capacity query module 11 is used to, after obtaining the target request sent by the target user through the client, determine the target user group in which the target user is located based on the preset capacity query logic, and query the user capacity quota corresponding to the target user, the user used capacity, and the user group capacity quota corresponding to the target user group.

[0080] The second capacity query module 12 is used to query the system total capacity corresponding to the network file system based on the preset interface provided by the network file system.

[0081] The target capacity obtaining module 13 is used to obtain the target total capacity and the target available capacity corresponding to the target user according to the user capacity quota, the user group capacity quota, the system total capacity, and the user used capacity.

[0082] The target capacity sending module 14 is used to send the target total capacity and the target available capacity to the client.

[0083] It can be seen that the preset capacity query logic is newly added in the application to control the query of the user capacity quota corresponding to the target user, the used user capacity, and the user group capacity quota corresponding to the target user group, so as to obtain the target total capacity and the target available capacity corresponding to the target user according to the user capacity quota, the user group capacity quota, the system total capacity, and the used user capacity. Thus, the target total capacity and the target available capacity corresponding to the target user can be sent to the client.

[0091] It should be noted that the target total capacity corresponding to the target user is jointly affected by the user capacity quota, the user group capacity quota, and the system total capacity, and is the minimum value among the user capacity quota, the user group capacity quota, and the system total capacity. For example, when the system capacity quota is greater than the user capacity quota, and the user capacity quota is greater than the user group capacity quota, the size of the target total capacity corresponding to the target user is the size of the user group capacity quota. When the user group capacity quota is greater than the user capacity quota, and the user capacity quota is greater than the system total capacity, the size of the target total capacity corresponding to the target user is the size of the system total capacity.

[0092] The target capacity obtaining unit comprises:
