I suppose the hda3 and hdc3 are to be the swap devices, so all you
have to do is:

(1) 	turn hda2, hda4, hdc2 and hdc4 into _physical volumes_, using
	partition id 8e and pvcreate, eg

	"pvcreate /dev/hda2 /dev/hda4 /dev/hdc2 /dev/hdc4"

(2)	create a _volume group_ out of these PV's

	"pvcreate <name of VG> /dev/hda2 /dev/hda4 /dev/hdc2 /dev/hdc4"

(3)	create a _logical volume_. This is where the filesystems are
	put on :)

	"lvcreate -n <name of LV> -L 88G /dev/<name of VG>"

(4) 	make filesystem

	"mkreiserfs /dev/<name of VG>/<name of LV>

that should be it.

good luck,

Nils
