there are no change in disk layout between 4.3 and 4.4 AFAIK

showing all PVs means you don't have configured lvm filter on the hosts, you
should run
vdsm-tool config-lvm-filter
on each host, see [1] for more details.
Not showing any PVs on may be caused by installed lvm filter (you can run it
again with --config 'devices {filter=["a|.*|"]}' to find out) or because there
are no PVs created yet, which is more likely as in previous log there was an
error during pvcreate.
