Illustratively, the life cycle and/or usage record of the target block storage device of step S109 is recorded to the status record table.
Through the embodiment, the use record of the target block storage device can be conveniently checked through the state record table subsequently, and the use condition of the target block storage device can be conveniently monitored through the state record table.
Fig. 7 shows a schematic diagram of a system architecture for implementing the block storage service, in which a first type of virtual machine is denoted as a consumer and a second type of virtual machine is denoted as a producer for understanding, and as can be seen from fig. 7, the architecture includes a scheduling system, a monitoring system, and a database. The scheduling system is responsible for receiving first requests of applying for the block storage devices sent by all consumers and distributing target block storage devices provided by a producer to all consumers based on the first requests of all consumers; the corresponding target block storage device is then mounted to the corresponding consumer. The scheduling system is also responsible for receiving second requests sent by the consumers for releasing the block storage devices, and unloading the mounted target block storage devices for the consumers based on the second requests of the consumers. The configuration table is created in the database, and includes how many producers each storage cluster is configured with, and at most, several disks (i.e., several block storage devices) can be produced by each producer at the same time. A state record table related to the block storage device is also created in the database and used for recording the block storage device information generated by the producer, including information of the size of the block storage device, the IOPS, whether the block storage device is used and which consumer the block storage device is used. The monitoring system is responsible for regularly checking the number of actual producers, comparing the actual producers with the configuration table, and informing the scheduling system of a comparison result, if the number of the actual producers is more than that in the configuration table, the scheduling system deletes the producers; if the actual number of producers is less than the number in the configuration table, the scheduling system creates producers to ensure that the number of producers meets expectations.
After the dispatching system is started, the initialization of the system is automatically completed according to the configuration table, including the automatic creation of a producer. After the dispatching system is started, the dispatching system waits for a request of a consumer for applying the block storage device and receives a post-application processing requirement, so that the block storage device can be quickly provided for the consumer. After the scheduling system is started, the monitoring system completes the initial creation of the producer, and continuously monitors the state of the producer, so as to ensure that the available producer meets the configuration number in the configuration table.
When a consumer needs to use block storage, the scheduling system distributes the request of the consumer to the producers corresponding to different storage clusters according to the different storage clusters, the producers divide storage resources from the storage clusters, the configuration of the storage clusters is updated, the required block storage devices are created, and then the block storage devices are unloaded to become independent block storage device resources. After the steps are completed, the producer returns the information of the block storage device to the consumer, the scheduling system executes mounting of the block storage device to the specified consumer, so that the creation and mounting of the block storage device are completed, and the consumer can use the block storage device.
That is, when a consumer applies for using a block storage device to the scheduling system, the producer completes the creation of the block storage device, and the scheduling system mounts the block storage device to a designated consumer according to the information, so that the consumer can use the block storage device and record and store the information of the block storage device in the state information table. When a consumer applies for the unloading of the block storage device to the scheduling system, the scheduling system executes unloading operation to unload the block storage device from the consumer, so that the block storage device is changed back to a free state and can be used by other consumers. Optionally, the original consumer's data on the block storage device is maintained by default and its usage record and current status are recorded in the status information table. The block storage device in the free state belongs to the block storage device which can be used at any time, and the scheduling system manages all the block storage devices in a unified manner and records the states and the use records of all the life cycles of the block storage devices.
Through the system architecture, the specified virtual machines can be used as producers according to the configuration information to produce the required block storage equipment, and the produced block storage equipment supports free mounting and unloading in the same storage cluster; when a consumer needs to uninstall the block storage device, the scheduling and uninstalling of the storage device from the consumer can be realized; the method has the advantages that the free scheduling of the block storage devices is realized, the block storage devices are distributed from different storage clusters to consumers according to the demands of the consumers, the formatting of the block storage devices, the mounting and the dismounting of the block storage devices and the like, all operations can ensure the safety of data stored on the block storage devices, the low-version virtual machine can provide a block storage service function, and the problem that the low-version virtual machine cannot provide the block storage for the cluster to use is solved.
It should be understood that the architecture diagram shown in fig. 7 is an alternative specific implementation manner, and those skilled in the art may make various obvious changes and/or substitutions based on the example in fig. 7, and the obtained technical solution still belongs to the disclosure scope of the embodiment of the present application.
