Raid Setup?

[ogden nefix]

Hi,

The person who set up this RAID left about a year ago but we are trying 
to figure out how we set up the RAID on this 2850 running Debian:

4 Hard drives - all same size/config and df:

Filesystem           1k-blocks      Used Available Use% Mounted on
/dev/sda3             33546132   5860364  25981676  19% /
/dev/sda1                93309      9338     79154  11% /boot
/dev/sda4             35364880   3351096  30217316  10% /opt
