[linux-lvm] LVM preference for multipath verses disk/by-id/scsi

I just this on a system with these in the lvm.conf:
preferred_names = [ "^/dev/mapper/EMC_", "^/dev/[hs]d", "^/dev/cciss" ]
filter = [ "r|/dev/.*/by-path/.*|", "r|/dev/.*/by-id/.*|",
"a|/dev/mapper/EMC_*|", "a|/dev/cciss/*|" , "r/.*/" ]
After a pvscan and vgscan I did a vgimport. Guess what: A vgimport of
the volume group ignored the filters and preferred devices and imported
the vg with these PVs (only one PV shown for brevity, but the rest are
similar ):
PV Name /dev/dm-16
PV UUID ctz8rd-ew58-0pU8-FssR-x9pR-KSA9-mI4flw
PV Status allocatable
Total PE / Free PE 539 / 0
Unless, /dev/dm-16 is really some abstracted link back to a multipathed
device but I cannot work out this bit:
# ls -l /dev/mapper/
total 0
