Detailed Description
The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
The embodiment of the application discloses a storage volume creation method, which can distribute the capacity distribution of the storage volume according to the need and meet the customization requirement of users.
Referring to fig. 1, a storage volume creation method disclosed in an embodiment of the present application includes:
s101: creating a plurality of disk arrays in a storage pool, and dividing each disk array based on a preset logical storage space size;
In the embodiment of the application, a plurality of disk arrays can be created in the storage pool in advance, and each disk array is divided. Specifically, when the disk array is divided, the disk array may be divided based on a preset logical storage space size, that is, the logical storage space size is taken as a dividing unit, and the specific size thereof may be set according to a specific implementation scenario.
S102: receiving a creation request for creating a target storage volume, and acquiring a target disk array designated by an initiator of the creation request and the proportion of each target disk array in the total capacity of the target storage volume;
In this step, the user may initiate a creation request for creating the target storage volume, and after the system receives the creation request, the target disk array specified by the request initiator may be obtained, and the set proportion size of each target disk array in the total capacity of the target storage volume, and the distribution situation of the total capacity of the target storage volume in each target disk array.
As a specific implementation manner, after receiving a creation request initiated by a user for creating a target storage volume, the embodiment of the present application may return a visualized configuration interface to an initiator of the creation request; and receiving the target disk arrays designated by the initiator and the proportion of each target disk array in the total capacity of the target storage volume through a configuration interface. That is, the user may set the target disk array and the corresponding scale size through a configuration interface provided by the system.
It may be understood that, when the embodiment of the present application returns to the visualized configuration interface, all disk arrays existing in the current storage pool may be specifically displayed through the configuration interface; and receiving a selection instruction of the initiator for the disk array to determine a target disk array designated by the initiator. In this manner, the selectable disk arrays may be directly visually displayed to the user for selection by the user.
As another specific implementation manner, after receiving a creation request for creating a target storage volume, the embodiment of the present application may obtain, through a file import interface, a user configuration file uploaded by an initiator; and analyzing the user configuration file to obtain the target disk arrays designated by the initiator of the creation request and the proportion of each target disk array in the total capacity of the target storage volume. That is, the user can directly upload the pre-written configuration file including the designated target disk array and the corresponding proportional size information, and can obtain the user-defined configuration by analyzing the file.
S103: and selecting corresponding logic storage spaces in the target disk array to form the storage space of the target storage volume according to the proportion and the size, and completing the creation of the target storage volume.
It may be appreciated that, after determining the user-defined configuration, the storage volume may be created according to the proportional size specified by the user and the target disk array, and specifically, the corresponding logical storage space may be selected from the target disk array according to the specified proportional size, so as to generate the storage space of the target storage volume in a combined manner.
In one possible implementation, the user may specifically set the distribution order of the target storage volume capacities in the target disk arrays when setting the proportion of each target disk array in the total capacity of the target storage volume. By setting the distribution sequence, when the target storage volume is created, the logic storage space can be sequentially selected in the target disk array based on the distribution sequence until the designated capacity of the target storage volume is reached, and the creation of the target storage volume is completed.
In an embodiment of the present application, before obtaining a target disk array specified by an initiator of a creation request and a proportion of each target disk array in a total capacity of the target storage volume, a mode selection interface may be returned to the initiator of the creation request, so that the initiator selects a custom creation mode or a default creation mode; if the initiator selects a custom creation mode, entering a step of acquiring a target disk array designated by the initiator of the creation request and the proportion of each target disk array in the total capacity of the target storage volume; if the initiator selects the default creation mode, selecting corresponding logic storage spaces from all the existing disk arrays in the storage pool to form the storage space of the target storage volume by default according to the average allocation proportion, and completing the creation of the target storage volume.
That is, the embodiment of the application can provide the user-defined creation mode and the default creation mode of two storage volumes, and can firstly return the mode selection interface to the user after receiving the request of the user to create the storage volumes. The user may select custom creation or default creation through a mode selection interface. If the default creation is selected, all disk arrays in the storage pool can be automatically utilized to form the storage space of the storage volume, and the storage space of the storage volume is distributed in each disk array as evenly as possible. Referring to fig. 2, the default creation manner may specifically be: in this embodiment, a plurality of Raid, such as raid#1, raid#2, and raid#3, are created in advance in the storage pool. Each Raid divides a plurality of extensions according to the same granularity, the extensions represent basic capacity units, and can support various granularities, namely, the capacity of the extensions can be set according to the requirement. When creating volumes in a storage pool, if the capacity of which Raid is used is not specified, the storage space of the storage volumes is composed by default using the contents in all the raids, and the storage volume capacity is distributed in each Raid as evenly as possible.
According to the scheme, the storage volume creation method provided by the application comprises the following steps: creating a plurality of disk arrays in a storage pool, and dividing each disk array based on a preset logical storage space size; receiving a creation request for creating a target storage volume, and acquiring a target disk array designated by an initiator of the creation request and the proportion of each target disk array in the total capacity of the target storage volume; and selecting corresponding logic storage spaces in the target disk array to form the storage space of the target storage volume according to the proportion and the size, and completing the creation of the target storage volume. According to the method, after the disk array is firstly created and divided into smaller logic storage spaces, after the creation request for the target storage volume is received, the target disk array appointed by the initiator according to the self demand and the distribution proportion of the capacity of the target storage volume in the target disk array can be obtained, and then the target storage volume can be created by utilizing the storage space of the appointed disk array according to the appointed proportion, so that the customization requirement of a user is met, and the capacity distribution of the storage volume can be distributed according to the requirement. In addition, when the target disk array and the proportion are selected, the current capacity use condition of the disk arrays can be combined, and balanced use of a plurality of disk arrays is facilitated.
A specific method for creating a storage volume is disclosed in the following embodiments of the present application. Referring to fig. 3, the present embodiment creates a plurality of raids in advance in a storage pool, each of which is divided into a plurality of extensions at the same granularity. If three Raid are designated to be used by the user when creating the storage volume, for example, three Raid #1, raid #2, and Raid #3 are selected, and the capacity proportion is set by setting the distribution order of the capacity of the storage volume in the three Raid, for example, the capacity of the storage volume may be set to be distributed in the three Raid in the order of 1:2:1:3:1, then 1 extension in the Raid #1 is selected, then one extension in the Raid #2 is selected, and then the extensions in the Raid #1, the Raid #3, and the Raid #1 are sequentially selected. If the selected total capacity of the extension does not exceed the specified total capacity of the storage volume, selecting again according to the distribution sequence, and pushing the same until the selected total capacity of the extension reaches the specified total capacity of the storage volume.
Through the self-defining configuration mode, a user can self-define a selected Raid list and the capacity use condition of each Raid, so that the customization requirement is met; in addition, the content can support configuration of various granularities, so that the setting of the content granularity can be freely carried out according to management overhead and capacity utilization rate, and management overhead or capacity waste can be effectively reduced.
