I tried your settings, this is before reboot:
$ sudo pvdisplay --- Physical volume --- PV Name /dev/mapper/mpath1-part1 VG Name vg0 PV Size 2,00 TB / not usable 1,23 MB Allocatable yes (but full) PE Size (KByte) 4096 Total PE 524287 Free PE 0 Allocated PE 524287 PV UUID znfa6r-X7FD-VXTd-WdsJ-LAu2-8SdS-relheA
I created a PV and a LV: /dev/vg0/lv0, /dev/mapper/mpath1-part1 is present.
After reboot, /dev/vg0/lv0 is still there, but /dev/mapper/mpath1-part1 has disappeared and /dev/mapper/vg0-lv0 is showing up.
"pvdisplay" and "multipath -ll" give no output but /dev/vg0/lv0 can be mounted (probably using only one static path)
I used your "devices" part in /dev/lvm/lvm.conf and my /etc/multipath.conf contains only "defaults { user_friendly_names yes }".
If you want to run more tests, go ahead, I'm using a sandbox blade server.
