[0004] However, when the cluster network card fails, the current distributed storage system cannot detect the fault in time, and can only rely on the fault detection mechanism in each heartbeat cycle of the distributed storage system to detect the fault
However, the heartbeat cycle time is relatively long, and it is impossible to detect and report cluster network card failures in time
Therefore, when the cluster network card in the distributed storage system fails, it will easily affect the customer's storage business and greatly reduce the reliability of the distributed storage system

Embodiment Construction
[0044] The distributed storage system is to disperse and store data on multiple independent devices, use multiple storage servers to share the storage load, and use the location server to locate and store information, which improves the reliability, availability and access efficiency of the system, and is easy to expand. For a distributed storage system, data transmission can be realized through cluster network cards and service network cards. Among them, the service network card is used for communication between the cluster and external customers, and the cluster network card is used for data transmission between servers in the distributed storage system. In other words, the cluster network card is the key to realizing "distribution" of the distributed storage system.
[0045] At present, the distributed storage system can realize real-time fault monitoring of service network cards, but for the cluster network card, the existing technology cannot detect its faults in time, an...

The invention discloses a cluster network card monitoring method and device. The method includes: querying the IP addresses of all cluster network cards, and creating a corresponding periodic detection task; within a detection cycle, querying and storing the current working status of the cluster network card; Comparing the working state of the current cycle with the working state stored in the previous cycle; when the two are different, report to the distributed storage system. Add the cluster network card to the periodic detection task by analyzing the IP network segment and periodically detect the working status of the cluster network card. When a cluster network card fails, the fault status is synchronized to all nodes for storage and reported to the distributed storage system. Since the detection cycle of the cycle detection task is very short, which is much shorter than the heartbeat cycle of the distributed storage system, the fault state of the cluster network card in the distributed storage system can be detected in time and quickly recovered, greatly reducing the impact of the cluster network card failure on the business. The impact of user business improves the reliability of the distributed storage system.
Description
technical field [0001] The invention relates to the field of distributed storage systems, in particular to a method and device for monitoring cluster network cards. Background technique [0002] With the development of big data technology, the volume of metadata is also increasing. For big data, the access performance of metadata is the key to the performance of the entire distributed file system. At present, common metadata storage systems can be divided into two categories: centralized and distributed metadata storage systems. The centralized metadata management architecture adopts a single metadata server, which is simple to implement. But there are issues like single point of failure. Distributed storage systems spread metadata across multiple nodes. Furthermore, problems such as the performance bottleneck of the metadata server are solved, and the scalability of the metadata management framework is improved. [0003] In a distributed storage system, not only server...
