The process would go roughly: # put the necessary PV metadata on your raw devices pvcreate /dev/foo1 /dev/foo2 ... # make them to a volume group named my-volgroup vgcreate my-volgroup /dev/foo1 /dev/foo2 ... # cut out a logical volume from that, named my-logvol lvcreate --name my-logvol my-volgroup # put a file system on that logical volume mkfs.ext4 /dev/mapper/my-logvol # mount it mount /dev/mapper/my-logvol /home Now convince your boot setup to add the logical vols and mount them (this somehow involves fstab). Perhaps this [1] page is enlightening (just disregard the talk about vagrant(. I'm not yet quite sure you really want this, but hey. Learning new tricks is what keeps one happy. In my case I actually have a volume group (spanning a single physical device), but the use case is different: the physical device is encrypted (laptops get lost) and I wanted to have several partitions on it (and still move space from the one to the other in a pinch).
