It's been awhile since we posted this link, but it has suggestions

Expanding Storage on Linux-based Servers
By Matt Domsch and Tesfamariam Michael (February 2003 Dell PowerSolutions)

In response to growing user demands for storage, system administrators
frequently must add additional storage space to existing file
servers. This article describes how to add and configure local storage
space on a file server running the Red Hat Linux operating system
(OS). Three scenarios are presented: adding disks without a RAID
controller, adding disks to a new logical drive on a RAID controller,
and adding disks to an existing logical drive on a RAID controller.
