Problems solved by technology

[0003] The stability of the cluster file system directly affects the reliability of the virtualization platform. Compared with local file systems such as ext3, ext4, and xfs, the cluster file system provides functions such as lock protection and cluster heartbeat, which are more complex. However, in the actual application environment, many factors such as network status fluctuations between multiple nodes, node power failures, etc. will directly affect the HA (High Available, high availability) of the cluster file system.
[0004] The second-generation Oracle cluster file system OCFS2 provides the cluster management function, which can be disconnected in the heart

Example Embodiment

[0019] Hereinafter, the present invention will be described in detail with reference to the drawings and in conjunction with the embodiments. It should be noted that the embodiments in the application and the features in the embodiments can be combined with each other if there is no conflict.

[0020] The invention can avoid node restart, and automatically complete the node online and resume operation when the fault is repaired, thereby improving the reliability of the virtualization platform.

[0021] First, make the node in the stopped responding state not restart but just heartbeat offline, so as to avoid affecting other nodes; second, there will be a monitoring program in the user space to monitor the above events, once the above event occurs, it will be forced to uninstall the mount. File directory (delete file access path) and complete resource cleanup, such as locking resources, to prepare for subsequent recovery; again, the monitoring program will complete the failure repor...

Abstract

The invention provides a node management method and device. The method comprises the following steps of obtaining a node in a response-stopping state; deleting a target file access path used for storing the node, and conducting resource clearing; if the node is in an active state, obtaining the target file access path again. According to the technical scheme, when the node is in the response-stopping state, instead of restarting the node, the target file access path used for storing the node is detected, resource clearing is conducted, and when the node is in the active state, the target fileaccess path is obtained again, so that the influences on other nodes are reduced, the high availability of a cluster file system is improved, the reliability of a virtualization platform is improved,and therefore the virtualization platform can have better stability in a bad network environment.

Description

technical field [0001] The present invention relates to the technical field of cloud computing, in particular to a node management method and device. Background technique [0002] Virtualization is one of the key technologies for building cloud computing infrastructure, and the cluster file system plays a key role in virtualization. The cluster file system provides massive storage for the virtualization platform and provides parallel access capabilities for virtual machines. [0003] The stability of the cluster file system directly affects the reliability of the virtualization platform. Compared with local file systems such as ext3, ext4, and xfs, the cluster file system provides functions such as lock protection and cluster heartbeat, which are more complex. However, in the actual application environment, many factors such as network state fluctuation among multiple nodes, node power failure, etc. will directly affect the HA (High Available, high availability) of the clust...
