Well, they really should be alarming because the admin configured
a block layout setup and it did not work as expected.  So it should
ring alarm bells.

Yes, I expect that "pNFS: failed to open device
/dev/disk/by-id/dm-uuid-mpath-0x6001 ..." is very likely
operator error.

Actually that one is purely a debug message if at all - we don't know
if it is a mpath or non-mpath device, so we just try that first.
So that is totally fine to downgrade or turn into a trace point.  OTOH
a warning if you could open neither option would still be useful.
