How do you mean "remote drive" exactly? What type is it - is it iscsi, nbd...?
Or is it just a standard local drive attached to machine N2 you need to access on machine N1?
Is the drive shared? Or you have exclusive access to that drive for single machine?

In case the drive is shared amongst several nodes, you need to consider using clustered LVM (clvmd).

But essentially, you need to connect the remote drive first and then do a pvcreate and vgextend.
