If a filesystem chooses to depart from standard behavior it hardly seems realistic to expect developers to change all their programs to work around the incompatibility, particularly if workarounds lead to slow behavior or incorrect behavior or both. It shouldn't be that hard for the filesystem in question to invent inode numbers specific to the particular instance of the file. This sort of game has been played for years for Microsoft filesystems that lack inodes, and although the game can't be played perfectly in practice it seems to work well enough to keep users happy. Better, of course, would be proper support for inode numbers.

This makes sense for files - but I'm not convinced it makes sense for directories. The only cases I can think of where two directories could have the same inode and device number are bind mounts (and theoretically directory hard links) - and in both those cases it's legitimate for there to be different mounts on subdirectories.

POSIX says that a file is uniquely determined by its inode and device number. If you have a file system that reports the same device for different contents, your file system is broken, and it's no wonder that LOTS of Unix tools will fail to see the differences, because your file system is lying. We can't fix it in diffutils; that would have to be a fix in the kernel implementation of your file system driver. -- Eric Blake, Principal Software Engineer Red Hat, Inc. +1-919-301-3266 Virtualization: qemu.org | libvirt.org

I've tried to see the differences between two snapshots using diff: root@srv1:/mnt/protected# diff -qr tmp/ bkp_srv1/ and was amazed to find out that I can't. Here are the mounts: # the HEAD of the filesystem, mounted read/write: /dev/mapper/bkp_srv1 on /mnt/protected/bkp_srv1 type nilfs2 (rw,nosuid,nodev,noexec,relatime) # an older snapshot, mounted read only: /dev/mapper/bkp_srv1 on /mnt/protected/tmp type nilfs2 (ro,relatime,cp=2171601) At first I've decided that I've mounted the wrong checkpoint(snapshot) or have done something else wrong. Then I've double checked and have verified that there ARE actually different file contents on both mounts. So my guess is that diff checks the stat information on the dirs and if its the same dev&inode it does not bother to compare: root@srv1:/mnt/protected# stat tmp bkp_srv1 File: tmp Size: 4096 Blocks: 1 IO Block: 4096 directory Device: fd05h/64773d Inode: 2 Links: 4 Access: (0755/drwxr-xr-x) Uid: ( 0/ root) Gid: ( 0/ root) Access: 2014-02-11 22:16:50.545497340 +0000 Modify: 2014-02-11 22:16:50.545497340 +0000 Change: 2014-02-11 22:16:50.545497340 +0000 Birth: - File: bkp_srv1 Size: 4096 Blocks: 1 IO Block: 4096 directory Device: fd05h/64773d Inode: 2 Links: 4 Access: (0755/drwxr-xr-x) Uid: ( 0/ root) Gid: ( 0/ root) Access: 2014-02-11 22:16:50.545497340 +0000 Modify: 2014-02-11 22:16:50.545497340 +0000 Change: 2014-02-11 22:16:50.545497340 +0000 Birth: - I've checked the man page and was not able to find a usable diff option, e.g. force the comparison anyway. I've also run: rsync -a --dry-run --verbose tmp/. bkp_srv1/. and it shows the differences as expected. So "diff" is unable to do its job and show the differences between files/dirs when they exist. Thus I consider this to be a bug. P.S. I am aware that "diff" is crucially important software for lots of software developers and infrastructure and making changes to it or its interface (e.g. command line options) is a responsible task.
