I've discovered that it is possible to create files of size much larger than partition size. I thought that this is JFS bug, so I've filed a bugreport against it at http://bugzilla.kernel.org/show_bug.cgi?id=4345 Detailed info and testcase program are provided there. Later I've found that at least XFS and EXT3 filesystems have the same problem (though the resulting filesize is different for each fs). So the problem may be not in fs code but in some other piece of kernel. Could kernel gurus please investigate the problem? P.S. I'm using debian-amd64 with kernel 2.6.11.3. So I didn't check if 32-bit kernel has this bug. Max
