It really depends on the filesystem. For ext4 you can go all the way to zero bytes free with no issues, other than application issues from being unable to create files. (If you're talking about the root filesystem, then the "application" includes the OS so that isn't ideal.) Some filesystems don't handle running out of space well. These are usually filesystems that handle redundancy internally, but you really need to look into the specifics. Are you running something other than ext4 here? The space free almost always takes into account filesystem overhead. The issue is generally whether the filesystem can actually free up space once it runs out completely (COW might want to allocate space just to delete things, due to the need to not overwrite metadata in place). -- Rich
