Caused by: java.lang.RuntimeException: Error reading transaction logs, recovery not possible. To force the database to start anyway, you can specify 'unsupported.dbms.tx_log.fail_on_corrupted_log_files=false'. This will try to recover as much as possible and then truncate the corrupt part of the transaction log. Doing this means your database integrity might be compromised, please consider restoring from a consistent backup instead.

- 先清理磁盘空间，
- 备份graph.db,(tar -czvf /home/neo4j_bak.tar.gz graph.db)
- 然后进入graph.db目录,
- rm neostore.transaction.db.*
- rm neostore.counts.db.*
- 启动Neo4j（bin目录下执行：./neo4j start）
