title: How can I resize a fat32 file system in an LVM partition?
body: <p>Simple enough: I have an LVM partition (e.g. /dev/mapper/foo-fat) that contains a Fat32 file system.  Prior to reducing the size of this LVM partition (which I'll do with lvmreduce), I want to reduce the size of the Fat32 filesystem it contains.</p>
  
  <p>It looks like parted should be able to do it, but I can't find the magic invocation to make it work.</p>
