Power failure of node in a Hyper-V failover cluster

Milan 41 Reputation points

We have set up a failover cluster with multiple Hyper-V's running on it. When one node is down due to power problem, it takes several minutes for the hosted Hyper-V to reboot on another healthy node and restart all the services. Is is supposed to take this long? I have already shortened the resiliency period but it does not help much. I was expecting when a node is down, it will simply go through a live migration instead of a system reboot, which will be much quicker to resume the service. Is my assumption incorrect?

    Based on my understanding, Windows cluster failover is not for instant recovery but for recovery where you can afford to be down for a few minutes.
    It’s worth checking Leon and Tim’s post in the following thread, I hope it could help at your side:
