Thanks Alasdair.

It looks like my problem is actually deeper than I originally thought;

# vgdisplay -v foobar
[snip]
  --- Physical volumes ---
  PV Name               /dev/hda2
  PV UUID               weM5FG-L0Li-Ir7y-0B2z-MJoq-tvAg-C2Q19E
  PV Status             allocatable

  PV Name               unknown device
  PV UUID               PtbIxo-EmRo-ML7J-yhqx-gglD-ZayH-X6tuWE

Hmm, now how can I use vgreduce on an read-only VG to remove an unknown
PV?

# vgreduce --removemissing foobar

Gone.
