Hi siraj, There is now way to find out the free space on a partition using Java 5 (Lucene 3.0) or Java 1.4 (Lucene 2.9) without any native JNI calls. So Lucene cannot calculate it before optimizing.
With Java 6 it would be possible, but Lucene 3.0 is only allowed to use Java 5: File#getUsableSpace() A workaround would be to only check it conditionally using reflection on File.class. ----- Uwe Schindler H.-H.-Meier-Allee 63, D-28213 Bremen http://www.thetaphi.de eMail: u...@thetaphi.de > -----Original Message----- > From: Siraj Haider [mailto:si...@jobdiva.com] > Sent: Monday, November 30, 2009 11:58 PM > To: java-user@lucene.apache.org > Subject: Re: Disk full while optimizing an index > > Jason, > Thank you for your suggestion.
