I can't reproduce the problem in directories that I just "mkdir" myself.</p> <p>However, if "cp -a" the problem subdirectory somewhere else in the filesystem, I AM able to then recreate the problem there. In the original problem directory, the directory size is 10720, and any newly created file is 10720 in size. In one copy that I made, the directory size is 9728 bytes, and any newly created files are 9728 bytes.</p> <p>Very strange. I'm not yet sure what is special about the directory contents that makes it able to trigger this bug.</p> <p>I am able to read the files, and they just contain zeroes.</p> Lustre 2.3.54-2chaos, 2.3.57-2chaos.
