Is It Possible To Move Logical Volumes?

[Dave Bacon]

Hello,

I have a question about configuring Logical Volumes on my new Dell Power
Edge R710.  The server was ordered with Red Hat Enterprise 5.3 which
Dell has pre-installed.  Dell configured the drives on the server as
follows:

hd0 & hd1 (RAID1) = /dev/sda (146GB total capacity)
hd2, hd3, hd4, hd5 (RAID5) = /dev/sdb (438GB total capacity)

Dell has also pre-configured all of the logical volumes to reside on
/dev/sda.

This new server will primarily be an eMail server.  So I was thinking
about moving /var and /home to /dev/sdb which has more space.  This will
also place most of the data on the RAID5 drives and keep it separate
from the OS RAID 1 drives.

Could you please help answer my questions?

   1. Is it possible to relocate /var and /home to /dev/sdb using the LVM?
   2. Or is it best to simply leave /var and /home on /dev/sda (and
      maybe minimize their sizes on /dev/sda) and expand them to include
      space on /dev/sdb?
   3. If relocating /var and /home to /dev/sdb is not too messy, could
      you please provide an outline of the steps in the LVM I would need
      to follow to make it happen?  For example:
          * Do the changes need to be made in single user mode?
          * Can the GUI LVM be used to make the changes?

This server is not yet configured as an eMail server and there are only
two accounts on the server (root, and mine).

Any advice would be greatly appreciated.  Thank you.
