Sorry if I confused anyone.

I think I have it figured out but here's another go at what I want to do:

I have 3 HDDs on my MBE and 1 HDD on the SBE.  Mythtv recordings are 
stored in both places.

Applications running on the MBE only see two partitions.  The /boot 
partition and 1 other Logical Volume.

I want to separate out the mysql data base and keep it on it's own HDD 
on the MBE to improve disk access (or so I'm lead to believe).

To do this I want to remove a 200GByte HDD from those HDDs making up the 
1 Logical Volume on the MBE.  Right now, that means I need to reduce the 
disk usage on the MBE by about 170GBytes (there is already about 30 
GBytes free now).  Afterwards, I will migrate files off the 200GByte 
Physical Volume which resides on the HDD to be removed from the Logical 
Volume.

But which recording do I need to delete in order to gain the 200GByes 
free space on the MBE?  I still don't think there is a way to tell.

What I think I can do is increase the head room on the MBE by changing 
the amount of free disk drive space needed from 10GBytes to 200GBytes.

...thanks
