So I have just set up an HA environment where I have a master server and instances of an application using Neo4J embedded talking to that cluster. Everything seems to work if the state of both databases is the same.
However if I delete all data from my slave instance, and have it join the cluster, I expect the data from the cluster to propagate into the slave instance. Instead I get errors with what appears to be Neo4J spatial. I have Neo4J spatial in my application, and the server plugin installed in the on the master server side.
An example of the stack trace I get:

Does Neo4j Spatial support replication across instances? Or more specifically restoring the spatial index to a new empty instance that joins the cluster for the first time?
An update to Neo4j spatial to version 0.15-neo4j-2.2.6 fixes this issue. So you need to be using Neo4j 2.2.6 in order to have Spatial indexes replicate properly

So I'm trying to deploy 2 instances of Janusgraph (v 0.3.1) to insert data in the same keyspace of ScyllaDb backend. To do that i deploy 2 janusgraph containers with docker. The first one is starting without errors and creates the keyspace in my ScyllaDb but the second one displays some errors.
So my Janusgraph containers works on a cluster while my backend works on another cluster. Actually, I tried with only one container to restart it when my keyspace Scylla is already created and I have the same problem.
I also found a script clean.groovy that allowed to force shutdown the graph instances opened. But nothing works...

I think all those errors are created by this :
Caused by: org.janusgraph.core.JanusGraphException: A JanusGraph graph with the same instance id [0a0a01657-node11] is already open. Might required forced shutdown.
And this is the script clean.groovy
graph = JanusGraphFactory.open('janusgraph.properties')
mgmt = graph.openManagement()
instances = mgmt.getOpenInstances()
instances.iterator().findAll {
!it.contains('current')
}.each {
mgmt.forceCloseInstance(it)
}
mgmt.commit()
So did anybody solved this problem of graph ?
Thanks in advance.
I finally got answer ! So you can use ConfiguredGraphFactory but it failed for me. So for the first container i started it normally but the second one i added another configuration in the janusgraph.properties file :
graph.replace-instance-if-exists=true`
And it works perfectly !
I have running the neo4j community version from last 5 months and it was working fine. But today all the storage space on my machine where neo4j is running got exhausted. So I deleted few files not related to neo4j. But still, neo4j was not responding to the queries. So I restarted neo4j. But it does not start anymore. Can anyone point me in the right direction?
Here are the logs

I'm running DSE 4.5.1 on a 3-node cluster in AWS with RF=3. One of the nodes gets this error in the system.log. See (long) stack trace below. I would like to understand what the error means or implies. Is this a cause for concern? Lastly, how do I resolve the error?

I got Neo4j working on my Ubuntu Server, but after a update of Openssl and a reboot, i only get critical errors at startup.
I removed neo4j and reinstalled it (removed my manual Installation and installed it as a package with apt-get )
Still errors at startup and the Java stacktrace is not helpfull for me.
My Java looks fine and can run all other java Applications, i use:
java -version
java version "1.7.0_65"
OpenJDK Runtime Environment (IcedTea 2.5.2) (7u65-2.5.2-3~14.04)
OpenJDK 64-Bit Server VM (build 24.65-b04, mixed mode)
Hope someone knows an answer to it.
Here is the ErrorLog:

I'm using Windows 7 as host system and Java 1.7.40. I checked if there is a process locking the graph.db folder or whatever, but like Process Explorer says, everything is fine.
Yesterday i was able to start the embedded database and fill it with my migration script, but i used Neo4J 2.0.0M-04 at this time.
Is this probably a bug in the latest release or what can i do to avoid it?
Best regards;
Marcus
