neo4j not starting after disk full

My neo4j server fails to start after I had a 'no space left on device' error. Unfortunately, the last backup is 2 days old. This is neo4j 2.0.0 used in a webapp via spring-data-neo4j. Is there anything that can be done to recover the database? The log is attached, but I guess its to generic to give real help.

 org.neo4j.kernel.lifecycle.LifecycleException: Component 'org.neo4j.kernel.impl.nioneo.xa.NeoStoreXaDataSource@39931f5e' was successfully initialized, but failed to start. Please see attached cause exception.

Early versions of 2.0 have a known issue when running out of disc space - this has been resolved with recent versions. You can recover by manually fixing the datastore - however this is a time consuming operation requiring lot of knowledge on the internals of Neo4j.
