The main limtation is that the witness always be connected and powered on to ensure quroum if one node became unavailable. The virtual machine must be rebuilt only on the remainig node, making this much slower than a scenario with more available nodes.

Hi AimanHakim,

Did you know any limitation of 2 nodes plus 1 witness setup?

Seem the cluster controller not failover to another node.

Hi, can you explain more in detail? I don't understand what's the issue u r trying to solve here

Yes. Health check has been performed. No issue.

What is the limitation of 2 nodes plus 1 witness?

Hi, have you performed an health check on your environment to ensure that your setup it's okay? the active member starts to became a cluster controller after a while, as the active cluster member awaits the missing member to became active again.
