    Hi. I was running some system checks on a server where I had created a
    partition for future use...
    This partition has 60GB, formatted with ext3 with largefile option
    (created with the sarge debian installer) and the only thing I can see
    there is the "lost+found" folder...

    df shows
    jpcl@linux:~$ df
    Filesystem 1K-blocks Used Available Use% Mounted on
    ...
    /dev/md5 58875084 32828 55897952 1% /backup

    or, using this output to be more visible
    jpcl@linux:~$ df -h
    Filesystem Size Used Avail Use% Mounted on
    ...
    /dev/md5 57G 33M 54G 1% /backup

    However, du shows:
    linux:/home/jpcl# du -sh /backup/
    20K /backup/

    ...

    So, where are those 33MB going to? Is it related to "largefile"? Or
    maybe by being ext3 (maybe the journal size)?
    What tool can I use to find out the filesystem details? The partition
    sizes we can find out with fdisk, cfdisk, or whatever... but how do we
    check the "what filesystem, what blocksize, what journal size", ...?

    Thanks
    Joao Clemente
