Hi! You need one work directory (not only wal) for each server node. If you have persistence enabled, once server nodes start, you need to activate cluster: ignite.cluster().active(true) this creates a cluster baseline topology. Please note that once cluster is activated, if you add a new server node, you need to update baseline with new server node id to make new server node join to cluster.
Take a look to https://apacheignite.readme.io/v2.5.0/docs/cluster-activation -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
