[linux-lvm] how to upgrade from rh70 to rh71

["Joe Harvell" <harvell@nortelnetworks.com>]

Hmm:

I never really thought about this when I decided to put all my
filesystems on LVM logical volumes; but how am I going to be able to
upgrade to RedHat 7.1? If I remember correctly, the installer has its
own custom kernel and root filesystem to boot into for the upgrade.

My setup is two IDE disks with 4 RAID-1 devices.  I have an LVM volume
group (/dev/w0) on one of these (/dev/md2), that has all my filesystems
on it (except /boot).

/dev/w0/root
/dev/w0/var
/dev/w0/usr
/dev/w0/home
/dev/w0/opt.

So the redhat upgrade kernel will need to have support for RAID and
LVM.  And it will need to run vgscan, and vgchange -ay.  And it will
need to have devfs support or it will need to use mknod to make the
directories enumerated above.  Does anyone know if it does all these
things?

Am I going to have to use my own rescue disk as the platform from which
to manually do the upgrade (by issuing the appropriate rpm commands?

Has anyone with a similar configuration done this?
