Check the usage of inodes, and use 'lsof' to check for deleted files
being held oopen. One of the great amusements of my life is when
people do silly things like create complex, bulky hardlinked arrays of
deep backup trees with "cp -al" and rsync commands that preserve
unchanged files as hard links, and forget that every directory in
every hardlinked directory tree is, itself, a distinct inode. Even if
the files are hardlinked and take up no space, you can run yourself
out of inodes with tools like "rsnapshot" if you don't pay a bit of
attention tho this.
