I have a Always On AG 2016, configured on Windows Server 2012 R2 – 2 node cluster. Quorum configured as
2 nodes + Fileshare witness, totally 3 votes.
Scenario 1: Now, either 1 node fails – remaining vote = 66.66 (majority) and cluster is up.
Scenario 2: Now, fileshare witness fails – remaining = 66.66 (majority) and cluster is up
Kindly help me understand the dynamic quorum and dynamic witness on scenario 2.
My doubts, post scenario 2:
Will it automatically take away 1 vote from either one of the nodes? If yes, remaining vote will be 33% not majority and single point of failure.
What will be the role of dynamic witness in this scenario?
Thanks in advance!.
