If another process has an index open for updates it will be locked and you can test that with IndexWriter.isLocked(directory), but that's about it. An OS command like lsof on unix could be used to see if any processes on the same server have index files open but if you're using NFS that won't detect processes on other servers. Lucene and NFS don't always work well together - generally better to use local files if you can.
