For ext2/ext3 filesystems, you can use resize2fs for this. I usually make the filesystem size smaller than the size I eventually want it to be (to allow a safety margin), then run resize2fs again (or ext2online) after shrinking the logical volume to get the filesystem using the full size of the volume.
