Embodiment Construction

[0023] Such as figure 1 As shown, the present invention introduces a multi-data server architecture. The distributed storage architecture separates metadata and data, and uses a dedicated metadata server to store metadata and process client requests for metadata. When the client wants to obtain a certain file data, it will first communicate with the metadata server to obtain the metadata describing the file data, that is, to obtain the storage location of the data in the data server cluster and other information; then the client communicates with the data server cluster, Get the data you want. Such as figure 2 As shown, in order to perform fast fault recovery, the present invention proposes to record the change of metadata with a flow log, that is, each metadata server will record the change content of metadata on the machine, and store it persistently in the form of a log, so that It can be recovered from the running log even when there is a hardware or software failure on...

Abstract

The invention relates to the field of cloud computing, in particular to a failure recovery method facing to a cloud operation system and an applied data distribution framework thereof. The failure recovery method and the data distribution framework use a flow journal to record changing of metadata, namely each metadata server can record metadata changing contents of the native machine, and the contents can be permanently stored in journal mode, so that when software and hardware failures occur to the native machine, the native machine can be recovered from the flow journal. The failure recovery method and the data distribution framework effectively solve the problem of high availability of data in the cloud operation system and can be applied to recovery of stored data in the cloud operation system.

Description

technical field [0001] The invention relates to the field of cloud computing, in particular to a cloud operating system-oriented fault recovery method and an applicable data distribution framework. Background technique [0002] The cloud operating system can perform unified management of hardware resources including processors, storage, and networks. In the current cloud operating system application deployment, data storage mainly has two purposes: (1) user interface storage, that is, storage provided to users; (2) storage required by the system, such as virtual machine image storage, currently, The data storage of the cloud operating system has problems such as low performance, poor scalability, instability, and insufficient security. Contents of the invention [0003] One of the technical problems solved by the present invention is to provide a cloud operating system-oriented data storage fault recovery method to improve data availability. [0004] The second technical...
