I have built and configured a Windows 2016 Data Center cluster with 2 nodes. I implemented Storage Spaces Direct. (S2D)

that technology basically creates a shared virtual disk at C:\ClusterStorage\Volume1 (both nodes see the same disk)

my question is around the Role of the cluster. Do i need to create a high availability role for fail over capabilities? Ie Generic Application, Generic server, Other server?

I feel like i can install VC on the shared disk but how with the clients know what node is active? In order to create a virtual IP for the cluster to listen on, i need a Role, don't I?

thanks.

You should install on the shared node. What do you mean by how will the Clients now? Will it not be the same dns name or ip?

in a cluster, you have to a Role. a Role defines 2 major things.

1. what is the defined process that is actually clustered. Ie, a service, an app, a process, etc
2. what is the virtual IP for the above service or app or process.

without criteria number 1, when a fail over occurs, how will the new primary node of the cluster know what process or service to start?
without criteria number 2, the client or web URL potentially will be pointing to an inactive secondary.

Now, i could get around criteria 2 with a load balancer, however, in order to set up a load balancer, it also has to listen to a port or process to know when to activate node 1 or node 2.

I could also ask a simpler question; when i failover the cluster, how does the new primary node know to start the VC service?

What options do you have for checking something? Can you check a process or service status?

the normal option would be to add a "Service" as a clustered "Role". This would allow the clustering service to control the Visual Cron service state. Ie, Node 1 is running the service and Node 2 is waiting for a fail over but the Visual Cron service is NOT running on Node 2.

However, adding the VC service to the Role is not possible. At least I was not able to find a way to add the VC service to a Role.

Dear Geof,

I beleive we need to install seperatly VS in both nodes and in the cluster disk , once done VS services will be running in both node and dont forget to make this is cluster enviroment in server setting in both the nodes

then create a generic service in cluster and add VS services to it , this is bring VS to cluster and failover then

I am also new to VS , anyhow this is what i am going to try this week as i am also in processing of setting up VS cluster envrioment

Make sure that the VisualCron service is running on the node. If yes, please send the file server_startup.txt to support@visualcron.com
