I upgraded last night to Ubuntu 16.04, and LVM has ( even when booting
back into 15.10 ) decided that two of my three physical volumes are
missing, but they are not:

psusi@faldara:~$ sudo pvs
  PV         VG      Fmt  Attr PSize   PFree
  /dev/md0   faldara lvm2 a-m  101.91g  58.91g
  /dev/md1   faldara lvm2 a-m    1.69t 264.86g
  /dev/sdb1  faldara lvm2 a--    1.82t   1.81t
psusi@faldara:~$ sudo vgchange -ay
  Refusing activation of partial LV faldara/Music.  Use
'--activationmode partial' to override.
  Refusing activation of partial LV faldara/Videos.  Use
'--activationmode partial' to override.
  Refusing activation of partial LV faldara/swap.  Use
'--activationmode partial' to override.
  Refusing activation of partial LV faldara/trusty-old.  Use
'--activationmode partial' to override.
  Refusing activation of partial LV faldara/vivid.  Use
'--activationmode partial' to override.

  Refusing activation of partial LV faldara/xenial.  Use
'--activationmode partial' to override.
  6 logical volume(s) in volume group "faldara" now active

If I use --activationmode partial, then all volumes are correctly
mapped, with no missing extents:

psusi@faldara:~$ sudo dmsetup table faldara-vivid
0 44040192 linear 9:1 2468358144
44040192 24969216 linear 9:1 2996840448
69009408 14876672 linear 8:17 2048
psusi@faldara:~$ sudo dmsetup table faldara-xenial
0 83886080 linear 9:0 98304

How can it claim the pvs are missing, and then go ahead and use them?
 Is there a way to manually clear the missing flag from the pv?
