I guess ext3 is layered on top of ext2 and maybe that overhead causes some loss of space. I don't know much, but this looks like a good web page for an overview of many file systems (you can click on a name in the left table margin to see a full encyclopedia entry): http://en.wikipedia.org/wiki/Comparison_of_file_systems Here's a related question: The choice of file system determines if ACLs... http://en.wikipedia.org/wiki/Access_control_lists ...can be used. What's the current status of ACLs on Linux? Are you guys using ACLs? Any tips? According to the Wikipiedia web page file systems (URL above), ext2, ext3, ReiserFS, XFS and JFS all support ACLs, but I'm not sure that they all run on Linux (do they?) and there is this note for ext2, ext3 and ReiserFS: Some Installable File System drivers and operating systems may not support extended attributes, access control lists or security labels on these filesystems. Linux kernels prior to 2.6.x may either be missing support for these altogether or require a patch. I would like to hear your experiences. Thanks. Mike -- Michael B.
