Does Nomad persist jobs in a single server setup? If I gracefully stop the (single) Nomad server and restart it, will I get my jobs back?
I’m reading here:
“In the case of an unrecoverable server failure in a single server cluster, data loss is inevitable since data was not replicated to any other servers. This is why a single server deploy is never recommended.”
What is an unrecoverable server failure? When can it happen? If my VM reboots without gracefully stopping the server? Or in the case of an error inside the Nomad server?
My product is deployed on premise to customers, not in the cloud. Medium and large scale deployments will have multiple Nomad servers as recommended. But I need a cost-effective deployment model for my smallest customers. (No high availability needed, single server can cope with the load.) Adding multiple VMs will cost me too much.
