Doesn't the CONSOLE > MANAGE DISK REDUNDANCY already take care of this automatically? If so, I don't know why this HOWTO is needed. http://wiki.contribs.org/Raid#Adding_another_Hard_Drive_Later

== Another Option ==
Not recommended way as if you loose the drive you loose your system but you are in a world of hurt following these instructions and loose the drive as well. In all of these commands you would replace {drive} with the device you are working with (hda,hdc,sda,sdb,etc).
fdisk /dev/{drive}
Do the n,p,1 stuff. Then do T (change partition type), 1 (partition 1), 8e (Linux LVM). You can then write and save the partion.
Instead of formatting the drive do the following:
pvcreate /dev/{drive}1
The 1 at the end specifies the partition you created in fdisk.
Add the new partition to the volume group with:
vgextend main /dev/{drive}1
And check that you have new available space (it should show total size and free space):
vgs
Increase the root logical volume with:
lvresize -L +{space available} main/root
And finally increase the filesystem with:
ext2online -C0 /dev/main/root
Also see [http://wiki.contribs.org/Raid#Upgrading_the_Hard_Drive_Size Upgrading the Hard Drive Size] in the Raid article. The lvresize and ext2online commands can be used to take advantage of all of the available space.
By following these instructions you aren't just limiting space to a specific mount point/ibay but make it available to the entire system. You also don't have to mess with or tweak quotas. The space just becomes available.
If you are using a clean drive that is new to the system you shouldn't have to reboot or telinit 1 either.
