I imagine that without proper partition labels you'll also not get the benefit of e.g. the udev magic
that allows plugging OSDs in/out of different hosts. More generally you'll just be in a rather non standard configuration that will confuse anyone working on the host.
Ok, thanks for the heads up!
Can I ask why you want to use LVM? It is not generally necessary or useful with Ceph: Ceph expects to be fed raw drives.I am currently just experimenting with ceph. Although I have a reasonable number of "lab" nodes, those nodes are shared with other experimentation and thus it would be rather inconvenient to dedicate the raw disks exclusively to ceph.
