Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.Based on this
Embodiment in invention, for those of ordinary skill in the art under the premise of creative work is not made, what is obtained is every other
Embodiment, belong to the scope of the present invention.
In order that those skilled in the art more fully understand the present invention program, with reference to the accompanying drawings and detailed description
The present invention is described in further detail.
Next, a kind of method for file number quota that the embodiment of the present invention is provided is discussed in detail.Fig. 1 is the present invention
A kind of flow chart of the method for file number quota that embodiment provides, this method include：
S101：Receive the file that client is sent and request is set.
MDS ends can regard the port for being used to interact with client in storage system as.When client needs to set user
During file quota value, file can be sent to MDS ends request is set.This document set request can be used for trigger MDS ends to
Family file carries out quota setting.
Each self-corresponding file quota value of multiple users can be included within the storage system, each user is in storage system
The file number of middle setting is not quite similar, and in embodiments of the present invention, in order to distinguish file corresponding to different user, can use
User file represents the file corresponding to a user.
S102：Parse the file and request is set, obtain the quota information of correlation.
ID and quota value can be included in quota information.Quota value has corresponding relation with ID.ID
, can be in order to the identification of system of users with uniqueness.Quota value can be used to indicate that user within the storage system may be used
With the file number of establishment, after the file number that the user establishes within the storage system reaches the quota value, then can not deposit
New files again in storage system.
S103：Judge whether the quota information meets default file quota condition.
File, which sets request, is initiated by client, possibly can not take into full account the practical operation situation of storage system, from
And it is unreasonable to cause file to set the quota information in request to set.Therefore, match somebody with somebody according to quota information progress file number
, it is necessary to first judge the reasonability of the quota information before volume.
File quota condition is used to represent the condition that rational quota information should meet.Quota value is carried out to user file
During setting, the file number that the user has been set within the storage system is considered as, i.e., user's current file is total in storage system
Number.Specifically, it can search according to the ID carried in the quota information and to count file corresponding to the ID total
Whether number, the quota value for judging to carry in the quota information are more than or equal to the total number of files.
By taking file number quota corresponding to a user as an example, the meaning that quota value is set is to control the user storing
The number of file is established in system, when quota value is less than total number of files, illustrates the file that the user establishes within the storage system
Number has been over the quota value, and this meaning set with quota value is disagreed, and illustrates that the quota value is set unreasonable.
For example, the file number that user A has built up within the storage system is 100, the user A carried in quota information quota value is
80, if using the quota value 80 as current quota value corresponding to user A, and existing file number is 100 to user A,
Substantially it is not inconsistent with quota value, illustrates that the quota value is set and unreasonable.
When quota value is more than or equal to total number of files, then illustrate that the quota value is set reasonable, MDS ends can match somebody with somebody according to this
Volume value carries out follow-up file quota and set, that is, performs S104.
Multiple files can be included under same catalogue, these files can be referred to as to file group, in actual applications, be
Effective number for controlling corresponding file under the catalogue, often sets corresponding limit value, the limit for this document group
It is worth the higher limit of the file number for representing to include in this document group, when the file number in this document group reaches the higher limit
Afterwards, user can not then create new file under the catalogue.
Therefore, it is directed to there is provided the situation of file group limit value, using total number of files corresponding to user as according to progress
Outside the rational judgement of quota information, it is also necessary to enter to advance using the limit value of user's group as according to the reasonability to quota information
The judgement of one step.
Specifically, it can search and count surplus corresponding to the user's group belonging to the ID；Judge the quota
Whether value is less than or equal to the surplus.
Surplus can be limit value corresponding to user's group and the difference for the file number being had built up in the user's group.
Accordingly, when the quota value is more than or equal to the total number of files, and the quota value be less than or equal to it is described surplus
Surplus, then illustrate that the quota value is set reasonable, S104 can be performed.
It should be noted that it is to be directed in storage system to have file corresponding to the ID to perform above-mentioned judgement.But
It is possible that the situation of the ID is not present in storage system.The reason for ID is not present in storage system be probably
The quota value of the ID belong to for the first time set, therefore do not have in storage system correlation record information, it is also possible to be by
The ID is caused to be deleted by mistake in maloperation.Due to quota information corresponding to the ID, therefore pin being not present in storage system
To this kind of situation, then S104 can be directly performed.
S104：The quota information is set into quota information structure chart corresponding to metadata.
It is quota information map that quota information, which is set to the quota information structure chart in metadata cache area (MDCache),
In, system can automatically generate file number quota event context class, daily record rule triggering readjustment, so as to complete quota information
Set.
Meta data server receives the file that client is sent and sets request it can be seen from above-mentioned technical proposal；Parsing
The file sets request, obtains the quota information of correlation；Judge whether the quota information meets default file quota bar
Part；When quota information meets default file quota condition, then illustrate that meta data server can enter according to the quota information
The setting for part number quota of composing a piece of writing, then the quota information can be set into quota information structure chart corresponding to metadata.
The technical scheme realizes the function of user file quota on the premise of version stability and compatibility is not influenceed.Passing through will
Quota information set into quota information structure chart corresponding to metadata, it can be ensured that meta data server restart and it is active and standby
It is the stabilization of file number and quota information in the case of switching, accurate.
The facilities of quota information are known in time for the ease of client, when when the setting for completing the quota information
Afterwards, MDS ends can be to the client send feedback information.
The feedback information is used to represent that MDS ends have been completed the quota of file number.
Above-mentioned is the introduction deployed exemplified by setting file quota information, in order to fully meet actual demand, to use
More preferable experience is brought at family, can be set corresponding modification for the quota information of user file and be deleted function.
Next, will deploy to introduce to the modification process of user file quota value, the step includes as described in Figure 2：
S201：Receive the modification request that client is sent.
The quota value of ID and corresponding required modification can be carried in modification request, in order to enter with first wife's volume value
Row is distinguished, and the quota value of required modification can be referred to as into target quota value.
S202：Whether the target quota value for judging to carry in the modification request meets the file quota condition.
It is similar with above-mentioned S103 deterministic process to the deterministic process of target quota value, it will not be repeated here.
When target quota value meets file quota condition, then illustrate that the target quota value meets the requirements, then can perform
S203。
S203：According to the ID carried in the modification request, described in being preserved in the quota information structure chart
Quota value corresponding to ID is revised as the target quota value.

This document quota Modification growth function can be then directly invoked, realizes the modification of quota value.
Next, the deletion process to user file quota information is deployed to introduce, the step includes as described in Figure 3：
S301：Receive the removal request that client is sent.
S302：The removal request is parsed, obtains the required ID deleted.
ID can be carried in removal request.
S303：According to the ID, quota corresponding to the ID is searched from the quota information structure chart and is believed
Breath, and delete the quota information.
Quota information corresponding to each user is stored with quota information structure chart, the quota information include ID and its
Corresponding quota value.
File quota is previously provided with MDS ends and deletes function, is deleted when needing the quota information to user file
When, then it can directly invoke this document quota and delete function, realize the deletion of quota information.
