Neo4j 5.1.0 : Unable host a new database in the SECONDARY server in a causal clsuter

[bishnu12]

Neo4j version: 5.1.0
Operating system: Linux
Installation Type: Cluster

Hello, 

I am trying to setup a simple causal cluster of 3 PRIMARY and 1 SECONDARY node in 4 Linux VMs. I followed the documentation given for this https://neo4j.com/docs/operations-manual/5/clustering/servers/

I was able to deploy a basic cluster and the default neo4j database is avaialable in all the PRIMARY nodes. However, when I check my secondary node, I can only see the "system" database. So I used the command 

````ENABLE SERVER '478397ef-b637-43e4-8a98-779c461d7161' OPTIONS {modeConstraint:'SECONDARY', allowedDatabases:['neo4j']};`

However I am not able to see the database (neo4j) being synced to the secondary.

"478397ef-b637-43e4-8a98-779c461d7161" - This is a secondary server

Based on the docuementation given below

Hosting databases on added servers

Once enabled, a server does not automatically host databases unless:

• New databases are created.

• Existing database topologies are altered to request more hosts.

• Another server is transitioned to the Deallocating state.

• You explicitly rebalance the databases across the cluster.

I tried rebalacing the cluster using the command "REALLOCATE DATABASES", But that also didn't work.

Is there any other way I can host this database ? Or am I missing something. 

Thanks,

Bishnu
