[linux-lvm] PVmove can not work on lvm2-2.02.177

[Gang He]

Hello list,

As you know, pvmove can run on old version (e.g. lvm2-2.02.120 on SLE12SP2), 
But with new version lvm2-2.02.177, I can not run pvmove successfully in the cluster.
Here, I paste some information from my test, 
if you can know the cause, please help to figure out.
