Detailed Description
The core of the application is to provide a method for creating the storage volume, which can be mainly applied to the thick preparation volume in the storage volume, ensures that the volume operation of a user and the data filling operation of the thick preparation volume are not interfered with each other and are synchronously carried out through the state description of the newly added storage unit, and the user can not use the volume until the filling is completed, thereby realizing the instant use of the thick preparation volume and greatly improving the efficiency of creating the thick preparation volume and the experience of the user.
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present application more apparent, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments of the present application. 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.
Currently, the creation process of thick reserve volumes can be divided into two steps: creating volumes and filling volumes. The process of creating a volume is consistent with the process of creating a simplified volume, so that quick creation can be realized, but the process of filling a volume needs to perform write data filling operation on a quota space, and a great deal of time is consumed. Moreover, the thick provisioning volume cannot be provided for users in the process, otherwise a series of problems such as coverage of user data, inconsistent data and the like can be caused. Therefore, the creation efficiency and the user experience of the thick provisioning volume are greatly reduced, and most of the current scenes discard the thick provisioning volume matching application.
In order to solve the above-mentioned technical drawbacks, please refer to fig. 1, fig. 1 is a flowchart of a method for creating a storage volume according to an embodiment of the present application, the method includes:
s101: receiving a creation instruction;
s102: creating a storage volume according to the creation instruction, and configuring the state marks of all storage units in the storage volume as unused states;
s103: filling the memory cells in the unused state, and modifying the state marks of the corresponding memory cells to the filled state after filling.
There is no limitation on how the creation instructions are received, nor on the specific instruction form and instruction content of the creation instructions, it is readily understood that the creation instructions are used to create a storage volume, i.e., any instructions that can be used to create a storage volume can be considered a creation instruction in embodiments of the present application. The creation instruction may be actively acquired or passively received, for example, the creation instruction required in this embodiment may be obtained according to a real-time instruction of a user or a storage volume configuration instruction preset in the storage system.
After receiving the creation instruction, the storage volume may be created according to the creation instruction. The creation information that may be included in the creation instruction is not described here with emphasis, such as the creation position of the storage volume, etc., but with emphasis on the creation process of the storage volume. Specifically, for any newly built storage volume, a corresponding status flag is set. The status flag is used to record and feedback the application status of each storage unit in the storage volume. Of course, the type of status flag is not limited herein, and can be classified into an unused state, a written state, and a filled state, generally according to an application state. Of course, those skilled in the art may set other types of flags for the status flags based on the present embodiment, which is not limited herein.
After the storage volume is created, the state of all storage units in the storage volume needs to be configured first to be marked as an unused state, i.e. the initial state of the newly created storage volume is the unused state.
Thereafter, a filling operation may be performed, specifically filling the memory cells in an unused state, while marking the state of the filled memory cells as a filled state. It should be noted that this procedure only fills the memory cells that are in the unused state, and does not fill the memory cells that are already in the used state.
The usage state generally refers to an occupied state, and when a user performs a write operation on the storage volume, for example, a state flag of a storage unit corresponding to the write operation is changed to a used state. Of course, the user performs other operations on the created storage volume that occupy the storage unit, such as updating data after writing, etc., and the state flag of the storage unit is still in the used state. This is to distinguish the memory cells from other memory cells that are in an unused state. Of course, in practical application, different state marks may be set for the memory cells in different use states, which is not limited herein by way of example.
After the filling operation is performed, it can be ensured that enough memory units can be used when the memory units are subsequently called, i.e. the memory units in the used state cannot be called. Simply by performing a fill operation, it is ensured that the corresponding memory location is not preempted by other tasks or operations.
In a specific filling process, a background filling thread can be started, and the background filling thread is used for judging the state mark of a storage unit in the storage volume;
if the state of the storage unit is marked as an unused state, filling the storage unit;
and if the state mark of the storage unit is not the unused state, skipping the corresponding storage unit and executing the state mark judgment of the next storage unit.
I.e. during the filling process, reference is also made to the state flags of the memory cells, avoiding that an invalid filling operation is performed for memory cells that are not in an unused state. If the state mark of the storage unit is the written state, confirming that the target storage unit in the written state is in data writing or the data writing is completed, disregarding the target storage unit, and acquiring the state mark of the next storage unit. There is no limitation on how the padding operation is performed, and write data padding may be performed on a memory cell in an unused state to ensure that the memory cell is not occupied by other operations.
In the storage volume creation method provided by the embodiment of the application, when the storage volume is created, the state marks are added to all the storage units in the storage volume to mark the use state of the storage units, and when the storage units are not used, the storage units can be filled, and if the storage units are used, for example, a user can execute writing operation on the storage units, the filling of the storage units can be no longer executed. The method and the device ensure that the volume operation of the user and the data filling operation of the thick preparation volume are not interfered with each other and synchronously performed, the user can use the volume without waiting until the filling is completed, the instant use of the thick preparation volume is realized, and the efficiency of creating the thick preparation volume and the use experience of the user are greatly improved.
In a possible implementation manner, after the storage volume is created according to the creation instruction, the method may include the following steps:
determining the number of the storage units according to the volume size of the storage volume and the unit size of the storage units;
creating a state array according to the number; the state array is used to record the state flags of all storage units in the storage volume.
At this time, the corresponding complete execution process may refer to fig. 2, and fig. 2 is a flowchart of another method for creating a storage volume according to an embodiment of the present application, which specifically includes the following steps:
s201: receiving a creation instruction;
s202: creating a storage volume according to the creation instruction, determining the number of the storage units according to the volume size of the storage volume and the unit size of the storage units, and creating a state array according to the number;
s203: configuring state marks of all storage units in the storage volume corresponding state array to be unused states;
s204: and starting to fill the storage unit in the unused state, and modifying the state mark of the corresponding storage unit into the filled state after filling.
In this embodiment, the state marks of the storage units in the storage volume are recorded by using the state array. Specifically, after the storage volume is created, the number of storage units included in the storage volume is determined according to the volume size of the created storage volume and the unit size of each storage unit, so as to create a state array according to the number of storage units. It will be readily appreciated that the state array may be used to store a number of state markers that is not less than the number of storage units in the storage volume.
The specific structure of the state array is not limited herein, and may adopt data structures such as an array, a linked list, and the like.
In other embodiments, the state array may be created prior to creating the storage volume, requiring that the number of data units in the state array be as large as possible to meet the storage unit requirements in the storage volume.
After the state array is created, all the state marks of the storage units are unused state when the storage volume is just created. The state flags of all the corresponding storage units in the state array may be marked as unused, i.e., the state flags of all the storage units in the state array corresponding to the configuration storage volume are all unused. Meanwhile, in a specific application process, corresponding state values may be set for the "unused state", "used state", and "filled state", for example, "0", "1", and "2" may be used to represent the above three states, respectively, so that the corresponding state values are filled in the state array according to the actual state of the memory cell.
For example, if a memory cell in an unused state is filled, the state flag of the memory cell in the state array may be modified from the unused state to the filled state.
If a user writing instruction is received, writing is carried out on a certain storage unit, and the storage unit is indicated to be occupied by a certain operation of a user, and then the state mark of the storage unit in the state array is changed from an unused state to a used state.
When the storage volume is filled later, the storage volume is filled according to the state marks in the state array, namely, only the storage units with the states marked as unused states are filled, and the storage units in the used states are not filled any more.
Referring to fig. 3, fig. 3 is a timing chart of a storage volume creation process provided by an embodiment of the present application, and fig. 3 illustrates an example of a thick preparation volume, a user may issue a creation instruction to create the thick preparation volume, and an RBD thread, that is, a thread in a block storage device, creates the thick preparation volume according to the creation instruction, creates a background filling thread after the creation of the thick preparation volume is completed, and then feeds back information of success of creating the background filling thread to the RBD thread, where the RBD thread may feed back a creation success message of the background filling thread and the thick preparation volume to a front end where the user is located.
If the user performs read-write operation on the thick standby roll, the read-write operation is still realized through the RBD thread, but at the same time, the background filling thread can also perform filling operation on the thick standby roll, and the two operations are not mutually influenced. Except that the background fill thread only fills memory cells that are in an unused state and no longer performs fill operations for memory cells that have been used by the user. The read-write operation of the user can be normally performed.
As can be seen from the foregoing, the present embodiment focuses on adding a state description of the memory cell, and recording the usage state of the memory cell in the form of a state flag. The main distinction can be made between an unused state, a filled state and a used state. After the storage volume is built, setting the states of all storage units to be unused states, changing the corresponding storage units from the unused states to filled states after filling, changing the storage units corresponding to the writing operation from the unused states to the used states if the writing operation is received, and distinguishing the use states of the storage units by using different state marks.
The following is a specific application procedure of the present application:
1) State description of newly added block memory cells: unused, filled and written. The unused state is used for marking that the block storage unit is not filled and writing data, the filled state is used for marking that the block storage unit is being filled or is filled, and the written state is used for marking that the block storage unit is writing data or has been writing data by a user;
(2) After creating the volume, all storage units are set to "unused state". First, the number N of block storage units of a volume is calculated from the volume size and the individual block storage unit size. Then, a block storage unit state description array Status (N) is created for the volume to describe each block storage unit state and set the initial state value to "unused";
(3) And starting a background task of the filling volume to finish creation. The specific flow of the fill volume background task is to determine the block storage unit Status (i).
If the state is the unused state, setting the state of the memory cell to be the filled state and starting filling operation;
if the state is the written state, the memory cell is indicated to be used by the user, and the judgment of the next memory cell is directly skipped.
(4) The user adds a state description when writing to the volume. When a user performs a write operation on a block memory cell, the state of the memory cell is first set to "written state", and then a data write operation is started on the block memory cell.
In this embodiment, the storage volume may be used by a user when created, and the volume operation of the user and the data filling operation of the thick provisioning volume do not interfere with each other and are performed synchronously. The user does not need to wait for a long filling process, the user experience is greatly improved, and the method can be integrated into the existing block storage system and has higher compatibility.
