NEO4J 1.6.M02 -Datenbank scheint beschädigt zu sein; Wie erhole ich es?

Question

Ich habe eine NEO4J -Instanz auf einer Ubuntu -Maschine, die während des Dienstes geschlossen wurde. Infolgedessen weigert sich der Service nun, zu beginnen:

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

und die Protokolle ...

Jede Idee wie kann

1. die Datenbank wiederherstellen?
2. Verhindern Sie, dass dies erneut geschieht, sollte die Maschine erneut versagen?

Danke

Aktualisieren:Versuchte zu rennen sudo ./bin/neo4j-shell -path data/graph.db/ Und das ist die Ausgabe

Answer 1

OK, leider führen Sie 1.6.M02 aus, was dieses bekannte Problem aufweist, das Ihre DB in diesem Zustand aufnehmen kann. 1.6 hat dieses Problem nicht. Es gab ein anderes DB, das dieses Problem auf der NEO4J -Mailingliste hatte, also habe ich dieses Tool erstellt: http://pastebin.com/kustcagm ein solches defektes Protokoll zu reparieren. Würden Sie sich wohl fühlen, um das zu kompilieren und zu laufen? Andernfalls könnte ich ein gebündeltes Glas zusammenstellen, das ein Skript wie:

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

und schick dich irgendwie.
