It should not happen. Can you please open a issue: https://issues.apache.org/jira/projects/LUCENE If you don't mind, please supply all relevant info you are able to provide on the issue: OS, filesystem, JDK version, any hints as to how you are using lucene (e.g. when you are committing / how you are indexing). There are a lot of tests in lucene's codebase designed to simulate the disk full condition and guarantee that stuff like this never happens, but maybe some case is missing, or some other unknown bug causing the missing files. Thanks
