Hi, I have a lock issue at "neo start" command. I have no other process running on database. I first tested on an existing db on neo 1.4.2, and got the lock error message on Ubuntu. The same on Red Hat worded fine (directory is NFS mounted, so I have exactly the same access rights and files).
To be sure, I downloaded neo 1.5 in a directory, using default "data" directory (so an empty database).The start command issued the same problem, see log below: 1/6/12 11:58:43 AM org.neo4j.server.NeoServerWithEmbeddedWebServer INFO: Starting Neo Server on port [7474] with [160] threads available 1/6/12 11:58:44 AM org.neo4j.server.database.Database INFO: Using database at /home/symbiose/osallou/neo/neo4j-community-1.5/data/graph.db org.neo4j.graphdb.TransactionFailureException: Could not create data source [nioneodb], see nested exception for cause of error at org.neo4j.kernel.impl.transaction.TxModule.registerDataSource(TxModule.java:158) at org.neo4j.kernel.GraphDbInstance.start(GraphDbInstance.java:105) at org.neo4j.kernel.EmbeddedGraphDbImpl.<init>(EmbeddedGraphDbImpl.java:190) at org.neo4j.kernel.EmbeddedGraphDatabase.<init>(EmbeddedGraphDatabase.java:80) at org.neo4j.server.NeoServerBootstrapper$1.createDatabase(NeoServerBootstrapper.java:65) at org.neo4j.server.database.Database.createDatabase(Database.java:81) at org.neo4j.server.database.Database.<init>(Database.java:64) at org.neo4j.server.NeoServerWithEmbeddedWebServer.startDatabase(NeoServerWithEmbeddedWebServer.java:179) at org.neo4j.server.NeoServerWithEmbeddedWebServer.start(NeoServerWithEmbeddedWebServer.java:87) at org.neo4j.server.Bootstrapper.start(Bootstrapper.java:87) at org.neo4j.server.Bootstrapper.main(Bootstrapper.java:52) Caused by: org.neo4j.kernel.impl.nioneo.store.UnderlyingStorageException: Unable to lock store[/home/symbiose/osallou/neo/neo4j-community-1.5/data/graph.db/neostore.nodestore.db] at org.neo4j.kernel.impl.nioneo.store.CommonAbstractStore.checkStorage(CommonAbstractStore.java:183) at org.neo4j.kernel.impl.nioneo.store.CommonAbstractStore.<init>(CommonAbstractStore.java:103) at org.neo4j.kernel.impl.nioneo.store.AbstractStore.<init>(AbstractStore.java:120) at org.neo4j.kernel.impl.nioneo.store.NodeStore.<init>(NodeStore.java:42) at org.neo4j.kernel.impl.nioneo.store.NodeStore.createStore(NodeStore.java:84) at org.neo4j.kernel.impl.nioneo.store.NeoStore.createStore(NeoStore.java:256) at org.neo4j.kernel.impl.nioneo.xa.NeoStoreXaDataSource.<init>(NeoStoreXaDataSource.java:140) at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:57) at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:45) at java.lang.reflect.Constructor.newInstance(Constructor.java:532) at org.neo4j.kernel.impl.transaction.XaDataSourceManager.create(XaDataSourceManager.java:77) at org.neo4j.kernel.impl.transaction.TxModule.registerDataSource(TxModule.java:152) ... 10 more Exception in thread "main" java.lang.NullPointerException at org.neo4j.server.Bootstrapper.start(Bootstrapper.java:96) at org.neo4j.server.Bootstrapper.main(Bootstrapper.java:52) Thanks Olivier -- gpg key id: 4096R/326D8438 (pgp.mit.edu) Key fingerprint = 5FB4 6F83 D3B9 5204 6335 D26D 78DC 68DB 326D 8438 _______________________________________________ NOTICE: THIS MAILING LIST IS BEING SWITCHED TO GOOGLE GROUPS, please register and consider posting at https://groups.google.com/forum/#!forum/neo4j Neo4j mailing list User@lists.neo4j.org https://lists.neo4j.org/mailman/listinfo/user
