Hi, I'm assigning the Cluster ID by setting the system property org.apache.jackrabbit.core.cluster.node_id. But, as the FileSystem is shared between nodes, is it possible to separate the FileSystems without loosing any data ? and, all FileSystems must be private (Repository, Workspace, Versioning) ? Thanks in advance.
