It's possible to have dual boot, like Fedora + Windows.  Is it not possible
to  have a  dual  boot,  like  FC6 and F8 ?

For LV  -  there is resize2fs,  and lvreduce commands.  

In this case,  disk would be expensive.  There is a Raid Array Controller, and
Fedora uses: 
Fusion MPT base driver 3.04.04 
Copyright (c) 1999-2007 LSI Logic Corporation

It would be nice to have it split up, so you could run test versions.

It does?

ext3 supports online resizing, but I think only for growing.

New disks are cheap. Adding a second disk is a safe way to accomplish 
what you want.

I have not resized LVM, but I have done with with straight ext2/ext3 
partitions. In fact, I can't see any advantage to me in using LVM.

Tbe procedure, some years ago, for making ext2/2 smaller was something 
like this. You do not have any partitions on the disk mounted.
0. Backup.
1. e2fsck -f
2. resize2fs to a new size. I suggest smaller than your target.
3. delete the partition.
4. Create the partition. Check very carefully that your new partition is 
at least as large as you resized to.
5  resize2fs to the partition size. If your partition is smaller than 
you resized to in step 2, you are in deep do do.

Note.
You cannot move the start point of any partition.
You can join two or more partitions to make one larger partition, but 
you can only do this and retain the (physically) first of the partitions.

If you have any doubts and care about your data, buy a new disk. If 
you're working on a laptop, you can fiddle partitions as you copy the 
data, and if you need to, you can copy Windows with ntfsprogs; one of 
the programs in the set, ntfsclone does the grunt work, but there are 
other useful tools in the set.
