Abstract

The invention discloses a method, system, device and storage medium for high availability of network attached storage. The method includes: configuring a first virtual machine and a second virtual machine in a server and building a network based on the first virtual machine and the second virtual machine Attach the storage cluster, and configure a monitoring module in the first virtual machine and the second virtual machine to monitor the network attached storage cluster; in response to monitoring a node with an abnormal state in the network attached storage cluster, cache the write operation of the file system to the first virtual machine. In a virtual machine and / or a second virtual machine; restart the network-attached storage resources of the node and determine whether the network-attached storage resources of the node are recovered successfully; and in response to the successful recovery of the network-attached storage resources of the node, the first virtual machine and / or the 2. Write operations cached in the virtual machine are written to disk. The invention ensures that the file system service provided by the network attached storage cluster is not interrupted when the system fails, and improves the reliability, operability and implementability of the cloud management platform.

Description

technical field [0001] The present invention relates to the field of network attached storage, and more particularly, to a method, system, computer device and readable medium for high availability of network attached storage. Background technique [0002] With the rapid development of computer application and network technology, digital information is showing an explosive growth trend, and users have put forward higher requirements for the availability and scalability of storage systems. For some computer systems that perform critical missions, the system is required to be able to run stably for a long time, that is, to have the ability to run without interruption. Temporary downtime will lead to data loss and catastrophic consequences. When a single file system fails, the business on the file system will inevitably be interrupted, and the business will continue after the failure is recovered. SUMMARY OF THE INVENTION [0003] In view of this, the purpose of the embodimen...
