How to add & use a secondary drive??

[dragnovich]

Hello I have plesk 7.5 reloaded for Linux (Red Hat ES 3)

But my actual 80GB HD is 85%+ full so Im planning to add a 300gb HD to the server, but how can I configure the Plesk to Use this second HD, and create the new sites in that HD. (and leave the old ones in the old)

Also how to do this even for a tird of four hard drive??

Thanks!
