Abstract

The invention provides a resource processing method and device for a multi-controller system. The method comprises the steps that a controller in the multi-controller system cannot sense the existence of an opposite side controller; the controller judges whether the opposite side controller loads a first resource pool according to a first use mark stored in the first resource pool, which is loaded by the opposite side controller before. According to the invention, the problems of high cost and risk of failure of a split brain detection mechanism in a multi-controller system are solved; without adding any third party equipment and adding a special quorum disk, whether a split brain state occurs in a multi-controller system can be detected, the cost is saved, and the reliability and the stability of detection are improved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a resource processing method and device for a multi-controller system. Background technique [0002] A multi-controller system with shared backend storage, consisting of multiple controllers. Under normal circumstances, the controllers use a detection mechanism (for example, heartbeat signal) to judge the status of each other. When one or some controllers shut down or leave, other controllers will take over the storage pool resources running on them. to ensure the normal operation of the system. If the communication between the controllers is interrupted or abnormal, the controllers will not be able to perceive the existence of the peer end and a split brain will occur. The following is an example of a dual-controller system. figure 1 It is a schematic diagram of a split-brain situation in a dual-controller system in the related art, as shown in figure 1 As shown, both contr...
