AI Technical Summary
Cloned volumes depend on parent snapshots, which means that parent snapshots cannot be deleted before cloned volumes, thus consuming cluster storage space and affecting read and write performance. Furthermore, current technology cannot eliminate the need for manual flattening operations, which degrades cloned volume performance. Additionally, cloned volumes require manual flattening operations after creation, impacting performance and cluster space utilization.
After the cloned volume is created, it automatically detects updates to metadata information, performs a flatten operation through a background flatten process, deletes the parent snapshot, and enables the cloned volume to be put into use quickly, avoiding the need to manually trigger the flatten operation.
Cloned volumes offer improved performance and increased cluster space utilization. Once created, cloned volumes can be quickly put into use, reducing manual operation steps and improving system efficiency.

Abstract
Description
Technical Field
[0001] This invention relates to the field of computer technology, and in particular to a method, apparatus, device, and medium for performing a flatten operation on a cloned volume. Background Technology
[0002] Block storage typically offers snapshot functionality, similar to taking a photo—saving a record of block storage data at a specific point in time. New volumes, called cloned volumes, can be created using block storage snapshots. Currently, cloned volumes have the following drawbacks: 1. Cloned volumes are not completely independent volumes; they depend on a parent snapshot. This means the parent snapshot cannot be deleted before the cloned volume, and it continues to occupy cluster space, potentially leading to low cluster storage utilization. 2. When reading or writing to a cloned volume, if an object in the cloned volume does not exist, a query will be performed in the parent snapshot, impacting read / write performance. To address these drawbacks, existing technologies perform a flatten operation on cloned volumes, synchronizing all data from the parent snapshot to the cloned volume. This eliminates the dependency on the parent snapshot, allowing it to be deleted independently. However, the flatten operation usually requires manual triggering, which degrades cloned volume performance. Furthermore, in some scenarios, customers need cloned volumes to be readily available after creation.
[0003] Therefore, how to enable cloned volumes to be quickly put into use after successful creation without manually triggering the flatten operation is an urgent problem to be solved in this field. Summary of the Invention

[0007] Detect whether the metadata information in the target object has been updated;
[0008] When the metadata information in the target object is detected to be updated, a target flatten process is created. Then, in the target flatten process, a flatten operation is performed on the target clone volume. After the flatten operation is completed, the parent snapshot is deleted.
[0009] Optionally, before returning a success message to the client after creating the target clone volume, the method further includes:

[0017] Optionally, before reading the metadata information in the target object at preset time intervals and detecting whether the metadata information in the target object has been updated based on the reading results, the method further includes:
[0018] Create the target service process;

[0026] The target flatten process creation module is used to create a target flatten process when it is detected that the metadata information in the target object has been updated.
[0027] The flatten operation execution module is used to perform a flatten operation on the target clone volume in the target flatten process, and delete the parent snapshot after the flatten operation is completed.

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0040] Cloned volumes are not completely independent volumes; they depend on a parent snapshot. This means the parent snapshot cannot be deleted before the cloned volume, and it will continuously occupy cluster space, potentially leading to low cluster storage utilization. When reading or writing to a cloned volume, if an object in the cloned volume does not exist, a query will be performed on the parent snapshot, impacting read / write performance. To address these drawbacks, existing technologies perform a flatten operation on the cloned volume, synchronizing all data from the parent snapshot to the cloned volume. This way, the cloned volume no longer depends on the parent snapshot, allowing the parent snapshot to be deleted independently. However, in general, the flatten operation needs to be manually triggered, reducing cloned volume performance. Furthermore, in some scenarios, customers need the cloned volume to be quickly put into use after creation.
[0041] Therefore, this application proposes a flatten operation execution scheme for cloned volumes, which eliminates the need to manually trigger the flatten operation and enables the cloned volumes to be quickly put into use after successful creation.
[0042] This application discloses a method for performing a flatten operation on a cloned volume. See also... Figure 1 As shown, the method includes:
[0043] Step S11: After creating the target clone volume, return a message of successful creation to the client and store the metadata information of the target clone volume in the target object; wherein, the metadata information is the information of the target clone volume created based on the parent snapshot.
[0044] In this embodiment, a parent snapshot is first created based on the parent volume, and then the target clone volume is created based on the parent snapshot. After creating the target clone volume, a success message is returned to the client. This allows the clone volume to be quickly put into use. Furthermore, this embodiment stores the metadata information of the target clone volume in the target object. This metadata information includes, but is not limited to, the target clone volume name and the name of the storage pool where the target clone volume resides. It should be noted that when creating the parent snapshot based on the parent volume, the rbd clone command is invoked, and the creation is performed based on the parent volume.
[0045] Step S12: Detect whether the metadata information in the target object has been updated.
[0046] In this embodiment, after creating the target clone volume, a message indicating successful creation is returned to the client, and the metadata information of the target clone volume is stored in the target object. Then, it is detected whether the metadata information in the target object has been updated. In this embodiment, detecting whether the metadata information in the target object has been updated specifically means: detecting whether new metadata information has been added to the target object.
[0047] Step S13: When the metadata information in the target object is detected to be updated, a target flatten process is created. Then, in the target flatten process, a flatten operation is performed on the target clone volume. After the flatten operation is completed, the parent snapshot is deleted.
[0048] In this embodiment, after detecting whether the metadata information in the target object has been updated, if the updated metadata information is detected, a target flatten process is created in the background. Then, in the target flatten process, a flatten operation is performed on the target cloned volume, and after the flatten operation is completed, the parent snapshot is deleted. In this way, since this application performs the flatten operation on the cloned volume through the target flatten process, there is no need to manually trigger the flatten operation, thus improving the performance of the cloned volume. Furthermore, deleting the parent snapshot improves the cluster's space utilization.
[0049] As can be seen, this application proposes a method for performing a flatten operation on a cloned volume, comprising: after creating a target cloned volume, returning a successful creation message to the client and storing the metadata information of the target cloned volume in a target object; wherein, the metadata information is the information of the target cloned volume created based on a parent snapshot; detecting whether the metadata information in the target object has been updated; when the updated metadata information in the target object is detected, creating a target flatten process, and then performing a flatten operation on the target cloned volume in the target flatten process, and deleting the parent snapshot after the flatten operation is completed. It is evident that this application returns a successful creation message to the client immediately after creating the cloned volume, enabling the cloned volume to be quickly put into use. Furthermore, since this application performs the flatten operation on the cloned volume through a target flatten process, there is no need to manually trigger the flatten operation, thus improving the performance of the cloned volume.
[0050] This application discloses a specific method for performing a flatten operation on a cloned volume. Compared to the previous embodiment, this embodiment further explains and optimizes the technical solution. See also... Figure 2 As shown, it specifically includes:
[0051] Step S21: After creating the target clone volume, return a message of successful creation to the client and store the metadata information of the target clone volume in the target object; wherein, the metadata information is the information of the target clone volume created based on the parent snapshot.
[0052] In this embodiment, a parent snapshot is first created based on the parent volume, and then the target clone volume is created based on the parent snapshot. After creating the target clone volume, a success message is returned to the client. This allows the clone volume to be quickly put into use. Furthermore, this embodiment stores the metadata information of the target clone volume in the target object. This metadata information includes, but is not limited to, the target clone volume name and the name of the storage pool where the target clone volume resides. It should be noted that when creating the parent snapshot based on the parent volume, the rbd clone command is invoked, and the creation is performed based on the parent volume.
[0053] Step S22: Detect whether the metadata information in the target object has been updated at preset time intervals.
[0054] In this embodiment, after creating the target clone volume, a success message is returned to the client, and the metadata information of the target clone volume is stored in the target object. Then, at preset time intervals, it is checked whether the metadata information in the target object has been updated. Specifically, this includes: reading the metadata information in the target object at preset time intervals, and checking whether the metadata information in the target object has been updated based on the reading result. It should be noted that before reading the metadata information in the target object at preset time intervals and checking whether the metadata information in the target object has been updated based on the reading result, the method further includes: creating a target service process; initializing environment variables and connecting to the cluster through the target service process, and creating a corresponding target scheduled task. In this way, this application can set the preset time interval through the target scheduled task and read the metadata information in the target object at the preset time interval.
[0055] Step S23: When the metadata information in the target object is detected to be updated, a target flatten process is created. Then, in the target flatten process, a flatten operation is performed on the target clone volume. After the flatten operation is completed, the parent snapshot is deleted.
[0056] In this embodiment, after detecting whether the metadata information in the target object has been updated, if the updated metadata information is detected, a target flatten process is created in the background. Then, in the target flatten process, a flatten operation is performed on the target cloned volume. After the flatten operation is completed, the parent snapshot is deleted. In this way, since this application performs the flatten operation on the cloned volume through the target flatten process, there is no need to manually trigger the flatten operation, thus improving the performance of the cloned volume. Furthermore, deleting the parent snapshot improves the cluster's space utilization.
[0057] As can be seen, this application proposes a method for performing a flatten operation on a cloned volume, comprising: after creating a target cloned volume, returning a successful creation message to the client and storing the metadata information of the target cloned volume in a target object; wherein, the metadata information is the information of the target cloned volume created based on a parent snapshot; detecting whether the metadata information in the target object has been updated at preset time intervals; when the metadata information in the target object is detected to have been updated, creating a target flatten process, and then performing a flatten operation on the target cloned volume in the target flatten process, and deleting the parent snapshot after the flatten operation is completed; as can be seen, this application returns a successful creation message to the client after creating the cloned volume, enabling the cloned volume to be put into use quickly, and since this application performs the flatten operation on the cloned volume through the target flatten process, there is no need to manually trigger the flatten operation, thus improving the performance of the cloned volume.
[0058] See Figure 3 As shown, based on the flatten operation execution method of the cloned volume, this application can include the following:
[0059] In this application, the `rbd clone` command is invoked to create a parent snapshot based on the parent volume, and then a clone volume is created based on the parent snapshot. Upon completion, a success message is returned, allowing the clone volume to be quickly put into use. Furthermore, the clone volume information is recorded to a specific object, and a background service process is created. This background service process first initializes environment variables and connects to the cluster, then creates a scheduled task. This scheduled task periodically reads information from the specific object to determine if the information has been updated. If updated, a flatten thread is created to perform the flatten operation and delete the parent snapshot. Because this application performs the flatten operation on the clone volume through the target flatten process, manual triggering of the flatten operation is unnecessary, thus improving the performance of the clone volume.
[0060] Accordingly, embodiments of this application also disclose a device for performing a flatten operation on a cloned volume, see [link to relevant documentation]. Figure 4 As shown, the device includes:
[0061] The message return module 11 is used to return a message of successful creation to the client after the target clone volume is created;
[0062] After creating the target clone volume, a success message is returned to the client, allowing the clone volume to be put into use quickly.
[0063] Metadata information storage module 12 is used to store the metadata information of the target clone volume to the target object; wherein, the metadata information is the information of the target clone volume created based on the parent snapshot;
[0064] The metadata information of the target cloned volume is stored in the target object. The metadata information includes, but is not limited to, the target cloned volume name and the name of the storage pool where the target cloned volume is located.
[0065] Metadata information detection module 13 is used to detect whether the metadata information in the target object has been updated;
[0066] Specifically, detecting whether the metadata information in the target object has been updated means detecting whether new metadata information has been added to the target object.
[0067] The target flatten process creation module 14 is used to create a target flatten process when it is detected that the metadata information in the target object has been updated.
[0068] When the metadata information in the target object is detected to be updated, a target flatten process is created in the background.
[0069] The flatten operation execution module 15 is used to perform a flatten operation on the target clone volume in the target flatten process, and delete the parent snapshot after the flatten operation is completed.
[0070] In the target flatten process, a flatten operation is performed on the target cloned volume, and after the flatten operation is completed, the parent snapshot is deleted. In this way, since this application performs the flatten operation on the cloned volume through the target flatten process, there is no need to manually trigger the flatten operation, thus improving the performance of the cloned volume.
[0071] As can be seen, this application proposes a method for performing a flatten operation on a cloned volume, comprising: after creating a target cloned volume, returning a successful creation message to the client and storing the metadata information of the target cloned volume in a target object; wherein, the metadata information is the information of the target cloned volume created based on a parent snapshot; detecting whether the metadata information in the target object has been updated; when the updated metadata information in the target object is detected, creating a target flatten process, and then performing a flatten operation on the target cloned volume in the target flatten process, and deleting the parent snapshot after the flatten operation is completed. It is evident that this application returns a successful creation message to the client immediately after creating the cloned volume, enabling the cloned volume to be quickly put into use. Furthermore, since this application performs the flatten operation on the cloned volume through a target flatten process, there is no need to manually trigger the flatten operation, thus improving the performance of the cloned volume.
