In a 2 node FCI cluster with file share witness, assuming the file share is unstable (inaccessible) due to network issues.
Case 1: File share is down (inaccessible) and during this time I patch/reboot node 2. If the cluster has allocated the voting power to node 1 (dynamic quorum) then all ok. If it has given the voting power to node 2 (dynamic quorum) then the cluster will fail at this point.
Case 2: Suppose I restart node 2. At this point the cluster will auto set the vote of file share to 0 (dynamic witness). During that moment if the file share becomes unstable (inaccessible) then the cluster will remain healthy.
Please correct me if case 1 and 2 are correct understanding.
And how do I prevent the auto failover? For example- is there some setting I can do in the wsfc manager to make sure it won't failover.
