LVM questions

[Tony Arnold]

I'm just in the process of installing Dapper on my laptop (6.06 Beta)
and I thought I would try configuring the disk using the logical volume
manager.

I got it to automatically create a volume group with two logical
volumes, one for root and the other for swap. But what I really wanted
was three logical volumes, root, swap and home. I couldn't find an
obvious way in the installer to configure this, so I took the two
volumes for now.

So my next task is to create a third logical volume called home by
reducing the root volume in size.

Are there any graphical tools for doing this along the lines of gparted?
I've googled and search the apt package lists, but not found anything.

I'm happy to use the command line tools, but I'm not sure about all the
steps necessary. I presumably have to reduce the size of the root file
system before I reduce the size of the logical volume. But there are
size rounding concerns that I don't fully understand.

Pointer to good tutorials on LVM that covers these topics would be
great, or just some general advice.

Many thanks in advance for any help.

Regards,
Tony.
