You mean you are given a file name and then you need to know the path to the file and then find the device the filesystem containing the file? Where are we starting? Exactly.

The df command coincidentally resolves the file name you give to it to the mount point and file system.

So you do not know the path. df <path> will display the filesystem
Let's start with this
Code:
find / -name file.name -type f |\
while read fs junk
do
    path=$(dirname $file)
    grep "^$path"  /etc/mnttab
done

This will work if /etc/mnttab exists on your machine Otherwise we need the OS.

era - I think the OP wants the device name. The standard for df is to show the filesystem - not the device.
