Did you partition your second array ? if not, you can create a PV like this: pvcreate /dev/sdb. "pvcreate" can initialize a disk or partition. - pvcreate /dev/sdb - vgcreate vg00 /dev/sdb Again, no sure what you want to do, but with 4 HD you should consider to build raid5 (hardware raid) and then create PV, VG, LV.
