To provide a little more explanation let me add for Francky that fuse filesystems are hacks to make something appear as a filesystem. They mostly work okay. But they often do not implement everything that is needed by a real filesystem. I am only familiar with sshfs fuse filesystem and it is missing a number of important interfaces, but can read and write files okay so I still use it in spite of deficiencies. Since chmod is detecting an error then it must report it. Since I see VirtualBox in the hostname I can imagine this is either an MS or Mac machine running VirtualBox with an installation of Ubuntu and with a fuse map back to an underlying FAT or NTFS filesystem and the underlying filesystem does not support Unix file mode bits. But that doesn't really matter. The point is that the entire chain must support the operation or there will be an error. The chmod command is just the messenger reporting this to you.=20 If you access those files through a "real" Unix-like filesystem then you won't get that error.

NTFS doesn't have any concept of the same file modes as a Unix-like filesystem. Therefore any adaption layer sitting between an NTFS layer and a Unix filesystem layer can only make compromises. It can't do what it can't do. For example, where would it store this information? What would NTFS do with it? > My conclusion is the following: if I want to execute chmod +x properly, > I need an ext (4?) partition on my machine, separated from the Windows 7 > NTFS system. Correct? Yes. It doesn't need to be ext2, ext3, ext4. It could be any POSIX compliant filesystem. That would include xfs, jfs, for example along with many others. If the files are stored on NTFS then NTFS can't do it. If you want Unix filesystem semantics then it must be on a unix filessystem. For example on the VirtualBox filesystem. If you chmod files in /tmp in the virtual machine everything works fine because that is using a real unix filesystem. I am sure that you thought that disk space was disk space and that you would store files on the host NTFS and reach into them using a fuse mount layer from the virtual machine. That works up to a point. The data in the file is the same data in the file. But you wanted to chmod the permission bits and those are not understood by NTFS.

In any case it would need to support Unix filesystem permissions along with user and group ownership and the full set of behavior. Until recently it was only possible to reliably read from NTFS because the necessary information for it wasn't reverse engineered yet. Recently this has been completed and it is now possible to write to NTFS. Given how it came about it is amazing that it works at all.
