Running Zope on SuSE, > did not do this. df is showing it because it occupies space. du is not showing it because the filesystem has marked it as deleted. I don't particularly know zope, so I can't really guess why Suse would have behaved differently - I can only guess that it had a different TMP directory than this machine does for www-data or zope, or that it used a zope session file that was smaller or something else entirely. This is actually how upgrades in place work, and why you can overwrite files in use on Linux (unlike for instance, Windows, where you get a "can't delete that file" message). You mark the file as deleted, but the running programs that are using it have a file handle open to it, so it doesn't actually go away - it's just inaccessable to anyone else who comes along later. -- -------------------------------------------------------------------------- | Stephen Gran | Why be a man when you can be a success? | | steve@lobefin.net | -- Bertolt Brecht | | http://www.lobefin.net/~steve | | -------------------------------------------------------------------------- Attachment:
