Re: Does PostgreSQL Stores its database in multiple disks?

Igor,

I would recommend you investigate LVM:

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

This enables you to string multiple physical units into a single volume -
as well as expand and grow the volume. I am unsure about postgres
consequences of this for as much data as you have, so I will leave it up
to others to comment about this.

However, my recommendation is for a modest investment of a third 120GB
drive and a RAID card, you could do RAID 5 with 3 disks and get 240GB of
storage.
