Split-brain detection method and device of dual-computer hot standby system and medium

The invention discloses a split-brain detection method and device of a dual-computer hot standby system and a medium, and is applied to the technical field of servers. According to the method, the current states of the distributed copy block devices of the two nodes in the dual-computer hot standby system are firstly obtained, and then a preset rule is compared with the current states of the distributed copy block devices of the two nodes in the dual-computer hot standby system. And if the preset rule is met, determining that the dual-computer hot standby system has split brain. Wherein the preset rule comprises simultaneous mounting of the distributed copy block devices of the two nodes in the dual-computer hot standby system and simultaneous unloading of the distributed copy block devices of the two nodes in the dual-computer hot standby system, and the unloading duration exceeds the preset duration. According to the scheme, the current state of the distributed copy block equipment of the two nodes is analy
