Abstract: A virtual disk processing method and apparatus belong to the field of storage technologies, where the method includes receiving delete information from a client system of a first virtual machine, determining, according to the delete information, at least one data cluster in a first virtual disk corresponding to a designated file, where the first virtual disk is a virtual disk corresponding to the first virtual machine, setting the at least one data cluster to be available, determining, according to a storage mapping table, a target physical disk block corresponding to the at least one data cluster, where a correspondence between a data cluster in the first virtual disk and a physical disk block is recorded in the storage mapping table, and setting the target physical disk block to be available.

Abstract: The present disclosure disclose a configuration management method and apparatus, and a device. A control device determines that an application message needs to be published to a target logical group. The control device obtains an identifier of the target logical group and queries, according to a gateway mapping table and the identifier of the target logical group, a gateway connected to each of the at least one target terminal, to obtain at least one target gateway. The control device generates based on the application message, a MQTT publish packet and sends the MQTT publish packet to the at least one target gateway, where the MQTT publish packet is used to instruct a target gateway that receives the MQTT publish packet to send a corresponding application message to each target terminal that is connected to the target gateway and that belongs to the target logical group disclosure
