Embodiment Construction

[0030] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0031] like figure 1 As shown, the system architecture of the storage cluster provided by the embodiment of the present invention includes four parts. The first part is the client 101, which interacts with the metadata server 103 to complete the metadata IO operation, obtains the storage location of the data, and interacts with the storage cluster 104 to complete the data IO operation and completes the reading and writing of data. The second part monitor 102 monitors the status of the metadata server 103 and the storage cluster 104 . In the third part, the metadata server 103 manages data storage and data access rights. The metadata server 103 stores metadata in the storage cluster 104 through interaction with the storage cluster 104 . The fourth...

Abstract

The invention relates to the field of cluster storage and provides a failure detection method suitable to a large-scale storage cluster. According to the failure detection method, a failure detection module is arranged in a storage cluster system, a failure detection fault model used in the method is a failure/recovery model, and a transmission mechanism of failure node information used in the method is a spreading model permanently immune to infectious disease. By use of the method, the failure detection time is enabled to be unrelated to the scale of the storage cluster, the expansibility is excellent, and a stable low load is guaranteed under the condition that the large-scale storage cluster changes constantly.

Description

technical field [0001] The invention relates to the field of cluster storage, and more specifically relates to a failure detection method suitable for large-scale storage clusters. Background technique [0002] With the rapid development of informatization and network technology, the rapid growth of data makes it impossible for people to accurately plan storage system solutions based on the prediction and estimation of data volume, and the price of storage hardware is falling rapidly with the development of technology, and gradually The need to expand storage nodes is conducive to improving the utilization of investment, and enterprises need storage systems with the ability to expand on demand. Cluster storage technology can well meet this requirement, and deploying large-scale storage clusters can achieve high performance, high availability, and high scalability. [0003] Failure detection is a process in which the inspector uses a certain detection model and algorithm to ...
