/dev/sdh1 no longer exists. Remember, we converted the drives to be LVM
physical volumes. There are no partitions any more. It's all in an LVM
volume backed by /dev/sdh (without the 1).

What *should* be mounted at the OSD paths are tmpfs filesystems, i.e.
ramdisks. Those would not reference sdh so of course those commands will
return nothing. Try "df | grep osd" and "mount | grep osd" instead and
see if ceph-60 through ceph-69 show up.
