I'm re-installing slackware 9.1 on my linux box,
trying to set up LVM and ReiserFs. I'm pretty new
at this, learning as I go along.
I originally installed to another partition, now
I've creating a fresh partition and following the
LVM how-to about how to set up a root volume group.
My questions are about partition and volume group size.
The first time I created a partition and PV I made
it 5GB and found that I had created the rootvg too
small by default to allocate enough space. So reading the
man pages I figured out that I need to specify a
certain extent size when I create the rootvg in order
to use the space properly. Right now the partition is
a little over 4GB and the rootvg is 3.97GB with an
extent size of 8MB. Is this small extent size a good
idea or will it cause problems later?
Thanks for any advice,

It'll 'limit' you to a maximum LV size of 512GB if that is an issue in LVM1.
Once you migrate to LVM2 there's no such constraint any more.

Thanks Heinz, that's not a problem since this is a
home system, only has 8GB and 60GB HD's. Will the
small extent make a difference in performance?

Smaller extents cause larger mapping tables in LVM1.
Typically you won't be able to see a performance difference.
