Trying out Mandrake 8.2 beta 3 I had some irregularities happen
while doing custom partitioning.

I was delighted to see LVM support in the Expert section of DiskDrake.

I was sad to not be able to mount / into a partition inside a logical
volume.

I created a logical volume and then tried creating 2 RAID 5 partions
inside the Logical Volume and a third RAID 5 partition outside the
LV all partitions and logical volumes being on the same hard drive.

This seemed to confuse things royally.  I had a great deal of difficulty
deleting the partitions created within the logical volume.  I ran into
division by zero errors when doing so. 

A key to successfull Logical Volume work seems to be rebooting after
committing major changes to the partition table (such as after creating
new logical volumes.)  I was eventually able to delete the partitions 
and the logical volume itself after a reboot.

FIREWIRE...
Is there a way to support firewire devices durring the installation.
For low budget large storage arrays I know of no better solution than
to create an array of Firewire storage devices using the Logical Volume
Manager.  

Here's a link that talks about supporting firewire storage on Mandrake.
http://www.mandrakeforum.com/article.php?sid=1501&lang=en
I envision having multiple firewire cards with up to 63 hard drives
interfaced per card.  Also striping data across interfaces to increase
IO performance.

Also some RPMs that I flaged for inclusion in the install didn't work
for some reason.  I received messages saying they could not be installed
continue Y/N.

The packages I can remember were:
zip
snort
snort-scarf
WindowMaker
Python-docs
Quanta
Sawfish-themes
Screem
vnc-doc
xmms-skins
xpdf
xtraceroute

Now after the RPMS were installed it reported that some of the packages
were not installed.  Clicked OK.

A Message came up saying "No HDLISTS FOUND".

After this point it sent me back to the Partitioning section.

Logical Volume Management is _REALLY_ important to businesses.  Just as 
important as Journaling filesystems are.  Logical volume Managers allow
you to "snapshot" your filesystem in time so you can backup your
filesystems exactly as they were when you took the snapshot.  And while 
the backup is going you can continue to modify databases for example 
without worrying about the backup becomming inconsistant.  All that's
required is to stop transactions on the databases for a moment whiles 
you take the snapshot.  The other really cool feature about LVM is that
it allows you to modify virtual partitions which span multiple physical 
disks on the fly.

I hope that my observations are helpful here.
