[linux-lvm] how to start running LVM under fedora test and 2.6 kernel?

[Robert P. J. Day]

  as an admitted novice here, what is the proper recipe for 
starting to use LVM (under RH's new fedora core test) with the
2.6.0 kernel?

  if i do a stock install, that would first of all be using a
2.4 kernel and (IIRC) the previous version 1 of LVM, no?  so
it's easy enough to install and get *that* configuration working.
but how do i move up?

  it's easy enough to build and boot under a 2.6 kernel, but
now i have some LVM volume groups that i'd like to convert to
LVM 2.  can i do that?

  am i making any sense?  it seems pretty clear that i can't
do all this in one step.  or can i, and i just haven't noticed?

Get the LVM2 tools from www.sistina.com and compile/install them
in a different directory (see configure options) if you want to co-install
them with the LVM1 tools.

Yes.

Boot 2.6 and use the LVM2 tools in the directory you selected
when you configured them.

See LVM2's vgconvert manual.
LVM2 is able to handle LVM1 formated voplume groups in case you want
to be able to swictch back to 2.4+LVM1. Of course you can get device-mapper
patches for 2.4 from our site and use device-mapper+LVM2 on 2.4 as well.

At least one additional step is necessary (get the LVM2 tools running on 2.6).
