Abstract: A hard disk snapshot method and apparatus based on Openstack platform. The method includes: initiating a cloud hard disk creation request based on a snapshot, and determining, on the basis of a type of a new cloud hard disk, a second storage backend that is about to accommodate the new cloud hard disk (S101); in response to the second storage backend being different from a first storage backend where an old cloud hard disk that stores the snapshot is located, and mounting the old cloud hard disk on one host machine (S103); creating the new cloud hard disk on the second storage backend on the basis of the type of the new cloud hard disk, and mounting the new cloud hard disk on the host machine (S105); and replicating the snapshot from the old cloud hard disk to the new cloud hard disk through the host machine (S107).

Abstract: A service orchestration method, apparatus and device for a physical machine, and a computer-readable storage medium. The method includes: creating a physical machine resource that inherits all attributes of a cloud host, and modifying the physical machine resource according to characteristics of a target physical machine to obtain a target physical machine resource; configuring an underlying driver of Ironic according to the characteristics of a target physical machine; and invoking the Ironic by means of nova, such that the target physical machine resource is used to perform service orchestration on the target physical machine when the Ironic is running. On the basis of implementing service orchestration on a physical machine, the target physical machine resource in the method is obtained by inheriting all attributes of a cloud host and performing modification according to the characteristics of a target physical machine.

Abstract: A method and apparatus for preparing an image on a cloud platform, and a device and a storage medium are provided. The method may include: receiving an image request for a target object, and obtaining a first storage backend of the target object according to the image request (S100); obtaining a second storage backend of a Glance service in the cloud platform, and comparing the second storage backend with the first storage backend (S200); and obtaining an image for the target object on the second storage backend in a cloning manner when the first storage backend is the same as the second storage backend (S300). According to the method, the first storage backend of the target object is obtained according to the received image request, and the second storage backend of the Glance service in the cloud platform is obtained.

Abstract: Provided is a method for auditing an abnormality of a block device in a cloud platform. By automatically auditing abnormal data of a path layer and a multipath layer, the accuracy of multipath and path information on a host and whether a link has a fault may be quickly analyzed, operation and maintenance personnel may discover problems as soon as possible, the problem troubleshooting steps are simplified, the operation and maintenance personnel are liberated from complex work of manual troubleshooting, the troubleshooting capability of a cloud computing platform is improved, the work of the operation and maintenance personnel is simplified, and the problems are rapidly positioned.

Abstract: Disclosed is a file storage management method. The method includes the following steps: sending a mount request to a management platform by using an agent service, and receiving a mount parameter returned by the management platform; recording the mount parameter into a configuration file of the agent service; determining, according to the configuration file, the address of a file storage to be mounted; and mounting a file system in response to a normal heartbeat between an address of a cloud host and the address of the file storage to be mounted. Further disclosed are a system, a computer device, and a readable storage medium.

Abstract: Provided are a service instance deployment method and apparatus, an electronic device, and a computer-readable storage medium. The method comprises: creating multiple processes in a target physical node, wherein each process is a RegionServer component and is used for executing one service instance; allocating a flag character to each service instance, and allocating a corresponding port to each service instance based on the flag character, wherein the flag character allocated to each service instance is used as a system parameter of the process corresponding to the service instance; and creating a corresponding log file and a corresponding Process Identification (pid) file for each service instance based on the flag character.
