Can you post the output of pvs?

Here is what it looks like on my myth backend:

store # pvs
  /dev/cdrom: open failed: No medium found
  Attempt to close device '/dev/cdrom' which is not open.
  PV         VG   Fmt  Attr PSize   PFree
  /dev/sda5  vg   lvm2 a-    21.80G    0
  /dev/sda7  vg   lvm2 a-   232.84G    0
  /dev/sda8  vg   lvm2 a-    82.50G    0
jmd0 store #
