Neo4j 1.6.M02 banca dati sembra non funzionare; come faccio a recuperarlo?

Question

Ho un esempio Neo4j su una macchina Ubuntu che spento mentre il servizio era alto. Di conseguenza, ora il servizio si rifiuta di iniziare:

Starting Neo4j Server... process [3807]... waiting for server to be ready.. BAD.
Neo4j Server may have failed to start, please check the logs.

e registri ...

idea di quanto sia possibile

1. ripristinare il database?
2. evitare che ciò accada di nuovo la macchina dovrebbe fallire di nuovo?

grazie

Aggiornamento: Provato in esecuzione sudo ./bin/neo4j-shell -path data/graph.db/ e questo è l'uscita

Answer 1

Ok, purtroppo si esegue 1.6.M02 che ha questo problema noto che può mettere il vostro db in questo stato. 1.6 non ha questo problema. C'era un altro db, che ha avuto questo problema sul Neo4j mailing list, così ho creato questo strumento: http://pastebin.com/KuSTcaGM per risolvere un tale registro rotto. Volete stare tranquillo compilazione e l'esecuzione di questo? In caso contrario, ho potuto mettere insieme un barattolo in bundle accompagnato uno script come:

$ ./fix-double-start-record-issue mio / db

e inviare in qualche modo.
