    We have an unusual problem with 'invisible' and disappearing files: some files are not
    visible in a directory using 'find' or 'ls' on the directory, yet they
    are visible using tools such as 'debugfs' or if you know the actual name
    of the file, you can use 'ls' to list it explicitly.

    For instance, in the directory:


    you can ls -la it, and find no files:

    stampy:~# ls -la /home/stampy/queues/sendsyphonemailqstore/q_dispatch
    total 8
    drwxr-sr-x 2 louisb staff 4096 Jun 25 11:45 .
    drwxr-sr-x 7 louisb staff 4096 Jan 4 14:05 ..

    Yet when you 'ls' the files directly (which we find from the log of a
    daemon that places them there), they are there:

    stampy:~# ls -la
    -rw-r--r-- 1 louisb staff 1 Jun 24 01:34

    This is occuring on two machines running Debian Woody, 2.4.25 and 2.4.18
    kernels. The filesystems have had fsck run on them, and the systems are
    not able to clean the /tmp directory because of these 'missing' files

    Other info:

    ext2 filesystems
    gcc version 2.95.4 20011002 (Debian prerelease)

    On both machines, the problems are showing up in the /tmp/CGI_Cache
    directory. The filesystems have not run out of inodes

    Any ideas what could cause this? It has happened on a 3rd machine now
    too. One of the machines uses hardware scsi RAID and the other two are
    using IDE (different chipsets, one VIA, the other AMD)

    Thanks for any pointers,
