A few things jump out in the configuration below: 1) You aren't assigning a Cluster ID. This is required. 2) Each cluster node is sharing the same database for the FileSystem implementations. This is wrong. Each cluster node needs a private FileSystem (as Thomas said below).
You can find them on the wiki link Thomas sent below, but the clustering prerequisties are worth repeating: 1) Each cluster node must have its own repository configuration. 2) Each cluster node needs its own (private) FileSystem and Search index. 3) Every cluster node must be assigned a unique ID. 4) A journal type must be chosen, either based on files or stored in a database. 5) The persistence managers must store their data in the same, globally accessible location (see PersistenceManagerFAQ). 6) A DataStore must always be shared between nodes, if used. You seem to be OK on #4 and #5, but not #1, #2, and #3.
