Information processing system operation method and device, electronic equipment and storage medium

The invention provides an information processing system operation method and device, electronic equipment and a storage medium, and is applied to the technical field of data system operation. The information processing system comprises a primary node and at least one secondary node, and the method comprises the following steps: for each secondary node, when the secondary node determines that the information storage state of the primary node is a storage state according to the storage duration of information in the primary node, closing an information storage function; when the secondary node determines that the information storage state of the main node indicates that the main node is in a downtime state according to the storage duration of the information in the main node, an information storage function is started, and the secondary node is updated to be the main node. According to the method provided by the invention, the problem of how to improve the operation stability and availability of the legacy syst
