(Sorry about the delay in replying. Had been busy on other tasks of the project.) This problem happened again today, i.e. there is only schema/ under data/databases/graph.db/ and no other files or directories.
There are no error on neo4j.log. After I kill -9 <neo4j_pid> (kill <neo4j_pid> didn't kill neo4j, nor did neo4j/bin/neo4j stop), neo4j was able to restarted normally (2nd time), i.e. there are files and directory index/. I restarted neo4j again (3rd time). While case1 (first time, failed case) and case 2 have some differences, but case 1 has exactly the same debug.log output as case 3.
