We've recently been looking at other similar cases, although not with the
unusual partitioning scheme you have.  Could you send the output of
systemctl status on each of the lvm2-pvscan services?  Also, try setting
obtain_device_list_from_udev=0 in lvm.conf to avoid some delays from udev.
Thanks, Dave
