1. you can’t have a two-server k3s cluster, at least not with etcd. You need an odd number of servers for quorum 2. longhorn does not currently support multi-cluster deployment with storage clusters and workload clusters. It is converged storage, meaning that the storage is colocated within the cluster that uses it.

Thank you for the insights @creamy-pencil-82913. For point 1, Apologies on x2 master node. We intend to increase it to x3 master nodes with etcd or to set it with external datastore with 3 worker nodes for optimal ha availability. For point 2, so it make sense to use option 2 - i.e setup workload nodes within storage cluster ( same cluster) and proceed with different grouping ( via namespace or pod labeling). Is this feature ( i.e. support multi-cluster deployment with storage cluster and workload cluster) is in your roadmap ? If not i think this will be greatly beneficial for devops team operations to offload storage within cloud-native environment which have many beneficial scenarios
