We currently have setup with multiple virtual machine hosts and two SANs for failover.
I was thinking about best way to deploy cluster in this configuration.
So I thought about deploying some nodes with master role for split-brain protection and make other nodes serve data only. Question I've been thinking of: is it possible to override default quorum value for write consistency so cluster may write data if one of SANs goes down?
I know about "discovery.zen.minimum_master_nodes" for master quorum and been searching for something like this for write consistency quorum. Another way to do this is just do not use quorum at all but I don't think this is optimal solution.
