neo4j 1.6.M02數據庫似乎損壞;我該如何恢復它？

Question

在服務啓動時關閉的ubuntu機器上有一個neo4j實例。 因此，現在的服務拒絕啓動：

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

和日誌...

任何想法如何能

1. 恢復數據庫？
2. 如果機器再次失敗，防止再次發生這種情況？

感謝

更新： 試圖運行sudo ./bin/neo4j-shell -path data/graph.db/這是輸出

好，不幸的是你正在運行1.6.M02具有這種已知的問題，可以把你的分貝在這種狀態下。 1.6沒有這個問題。還有另一個db在neo4j郵件列表上有這個問題，所以我創建了這個工具：http://pastebin.com/KuSTcaGM來修復這個破壞的日誌。你會感覺舒適的編譯和運行？否則，我會放在一起捆綁罐子伴隨的腳本，如：

$ ./fix-double-start-record-issue我/ DB

並以某種方式發送給您。
