Hi Matt

I've never used it but LVM might be an answer. There is a howto here:

http://www.tldp.org/HOWTO/LVM-HOWTO/

It starts ...

 Logical volume management provides a higher-level view of the disk
 storage on a computer system than the traditional view of disks and
 partitions. This gives the system administrator much more flexibility
 in allocating storage to applications and users.

 Storage volumes created under the control of the logical volume manager
 can be resized and moved around almost at will, although this may need
 some upgrading of file system tools.

 The logical volume manager also allows management of storage volumes in
 user-defined groups, allowing the system administrator to deal with
 sensibly named volume groups such as "development" and "sales" rather
 than physical disk names such as "sda" and "sdb". 

Sounds funky :)
