Description
Technical Field

Background
The thin provisioning technology is allocated to an application program for a plurality of times and in a small amount according to the capacity actually required by the current application, and when data generated by the application grows and the allocated capacity space is insufficient, the system can allocate a part of storage space from a back-end storage pool again in a supplementing manner, and the thin provisioning technology is widely applied to various storage systems as a capacity allocation technology. Through thin provisioning techniques, a user may create a thin volume. A thin volume includes virtual capacity and actual capacity. The virtual capacity refers to the total capacity that can be supported on the surface of the thin self-volume, and the total capacity is the capacity specified by a user when the thin self-volume is created, that is, the capacity displayed after the thin self-volume is mapped to the host end; the actual capacity is a capacity corresponding to a physical space actually used by the self-compaction volume, and the capacity reflects an actual situation of data stored in the self-compaction volume. For the actual capacity, the self-compaction volume may allocate a physical space of a certain size in an initial stage, and along with the continuous use of the user, when the previously allocated physical space is insufficient, a capacity expansion interval of a fixed size may be allocated, and similarly, when the capacity expansion interval is used up, the capacity expansion interval of the same size may be continuously allocated.

In actual use, the created self-compaction volumes may be small-capacity self-compaction volumes, the usage ratio of the head data of the self-compaction volumes to the volume data may be 1:1 or 1:2, and the capacity occupied by the head data of the self-compaction volumes is idle, so that the waste of storage resources is caused.
In view of this, how to implement more reasonable storage allocation for the self-compaction volume header data and avoid the waste of storage resources is a technical problem to be solved by those skilled in the art.

It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. 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.

Furthermore, the terms "comprising" and "having," as well as any variations thereof, are intended to cover non-exclusive inclusions.

Having described the technical solutions of the embodiments of the present invention, various non-limiting embodiments of the present application are described in detail below.
Referring to fig. 1, fig. 1 is a schematic flow chart of a method for allocating head capacity of a thin auto-compaction volume according to an embodiment of the present invention, where the embodiment of the present invention includes the following:
s101: and when detecting that the second thin self-compaction volume is created, acquiring a target occupied space capacity value of the header data of the second thin self-compaction volume.
In this step, a self-compaction volume creation monitoring thread may be preset, the thread establishes whether a storage system has a self-compaction volume creation request in real time, if the self-compaction volume creation request is monitored, after the request is executed, the size of header data of the created self-compaction volume, that is, the value of the volume of the space occupied by the header data, is, for example, 0.75M.
S102: judging whether the residual space capacity value of a data storage section storing the first self-compaction volume header data is not less than the target occupied space capacity value, if so, executing S103; if not, S104 is executed.
The first thin volume is a previously created thin volume adjacent to the second thin volume, that is, the creation time of the first thin volume is earlier than that of the second thin volume, and no self-thin volume is created between the creation time of the first thin volume and the creation time of the second thin volume. The data storage section in this step is a storage area for storing the first thin auto-thin volume header data. If the first thin volume does not exist, that is, the second thin volume is the first created thin volume, the data storage segment is a storage area initially allocated by the storage system for storing the header data of the thin volume.
S103: the header data of the second self-compaction volume is written to the data storage segment.
That is to say, as long as the data storage section storing the previous head data of the self-thin volume has enough space, the head data of the subsequent respective thin volumes are sequentially stored into the data storage section, instead of creating a self-thin volume, a head data storage section is allocated to the self-thin volume, so that the use of storage resources and the generation of more thin volumes under the same condition are increased, the storage performance is increased, and the storage capacity is prevented from being idle to cause waste.
S104: and writing the header data of the second self-compaction volume into the newly applied data storage section.
If the remaining space of the data storage section storing the header data of the last thin volume is not enough to store the header data of the currently created thin volume, the system allocates a new data storage section storing the header data for the thin volume. And sequentially and intensively storing the head data of the self-compaction volume in the memory space distributed in the same section, and continuously and intensively storing the head data of the self-compaction volume by using the next storage section after the head data of the self-compaction volume is fully stored until all the self-compaction volumes are created. For ease of management, the system may allocate the same amount of space occupied capacity for each data storage segment storing header data, e.g., 16M each.
In the technical scheme provided by the embodiment of the invention, a mode of intensively and continuously storing the head data of the self-compaction volume is adopted, as long as the current data storage section can store one head data of the self-compaction volume, the next head data of the self-compaction volume is continuously stored in the same data storage section, compared with the existing storage allocation, the method can greatly increase the use of storage resources under the same condition, generate more self-compaction volumes, better use the storage space, create more self-compaction volumes, effectively improve the storage performance, save the storage resources and avoid the waste caused by idle storage capacity.
In the above embodiment, how to perform step S102 is not limited, and the embodiment provides a method for locating a first thin volume header data storage segment, as shown in fig. 2, which may include the following steps:
s211: and presetting a minimum capacity value of the space capacity occupied by the head data of the self-compaction volume and a label self-generation strategy.
In this step, the minimum capacity value may be determined according to actual requirements, for example, 0.75M, which is not limited in this application. The tag self-generation strategy is used for automatically generating a storage-completed tag for the current data storage section if the residual space capacity value of the current data storage section is smaller than the minimum capacity value so as to identify that the current data storage section cannot continuously store the head data.
S212: and judging whether a data storage section which does not store the finished label exists, if not, executing S213, and if so, executing S214.
It can be understood that, since the tag self-generation policy is preset, whenever the available space capacity of the data storage section is not less than the minimum capacity value, the data storage section has no tag, and the data storage section can store the header data with the capacity value not greater than the minimum capacity value. It can be understood that the value of the head data occupied space capacity of the self-reduced volume is not less than the minimum capacity value, but as long as the data storage section has the tag, the data storage section cannot store the head data of the self-reduced volume, and a new data storage section needs to be applied for storing the head data of a subsequent self-reduced volume.
S213: and if the data storage section which does not store the finished label does not exist, automatically sending an application request of a new data storage section.
In this step, if the request for sending the new data storage section does not carry the occupied space capacity value of the new data storage section, allocating space for the new data storage section according to the default occupied space capacity value. And if the request for sending the new data storage section has the occupied space capacity value carrying the new data storage section, allocating space for the new data storage section according to the occupied space capacity value in the request.
S214: if the target data storage section which does not store the finished label exists, the target data storage section is a data storage section which stores the first thin self volume header data.
The header data of the self-compaction volume is sequentially stored in the memory space allocated in the same section in a centralized manner, and then the next storage section is used for continuing to store in a centralized manner after the header data is full, so that the data storage section without the label is the storage area for storing the header data of the previous self-compaction volume.
S215: and judging whether the residual space capacity value of the target data storage section is not less than the target occupied space capacity value.
In the embodiment, the tag for identifying whether the data can be stored continuously is set for each data storage section, so that the storage position of the current head data of the self-compaction volume is determined more efficiently, and the storage efficiency of the head data can be effectively improved.
The present application further provides another method for locating a first thin volume header data storage block, which is parallel to the above-mentioned manner, and therefore, as another alternative implementation, please refer to fig. 3, S102 may include:
s221: and presetting a timestamp generation strategy.
In this embodiment, the timestamp generation policy is used to automatically generate a timestamp for the corresponding data storage section after completing one header data storage. That is, all data storage sections in the system have a constantly updated time stamp, and when the time stamp is not updated for a period of time, there is a high probability that the data storage section has not enough space for storing header data. The data storage section with the timestamp closer to the current time of creating the self-compaction volume is the data storage section storing the last head data of the self-compaction volume.
S222: and determining a target data storage section which is closest to the creation time of the second thin self-compaction volume according to the time stamp of each data storage section to serve as the data storage section for storing the head data of the first thin self-compaction volume.
S223: and judging whether the residual space capacity value of the target data storage section is not less than the target occupied space capacity value.
According to the embodiment, the time stamps are set for the data storage sections, so that the storage position of the current self-compaction volume header data can be determined more efficiently, and the storage efficiency of the header data is effectively improved.
As an optional implementation manner, in order to timely store header data of a newly created thin self volume and further improve the efficiency of storing the header data, based on the above embodiment, the application may further include the following:
presetting a minimum capacity value of the space capacity occupied by the head data of the self-simplified roll, and setting a section self-application monitoring thread;
and calling a section self-application monitoring thread to monitor whether the residual space capacity value of the current data storage section is smaller than the minimum capacity value at intervals of preset time, and if the residual space capacity value of the current data storage section is smaller than the minimum capacity value, automatically sending an application request of a new data storage section.
The minimum capacity value of this embodiment and the minimum capacity value of the previous embodiment may be the same value, which may be selected based on actual situations, and this application does not limit this. The preset time interval may also be determined according to the frequency of creating the self-compaction volume in the current application scenario, for example, every 1 min. When the application request is sent, the size of the space of the new data storage section can be carried according to the actual situation, or the new data storage section can not be carried. And under the condition of not carrying, applying according to a default value.
It should be noted that, in the present application, there is no strict sequential execution order among the steps, and as long as a logical order is met, the steps may be executed simultaneously or according to a certain preset order, and fig. 1 to fig. 3 are only schematic manners, and do not represent only such an execution order.
