2.00 TB of PV "not usable"?

[Resending now that I've subscribed.]
[I've searched google and the list archives for the answer to this question, but without success.]

I've got a 3.18 TB PV member of a VG, and everything seems to be working fine. But, I noticed that the output of pvdisplay for my PV shows:

...
PVSize 3.18 TB / not usable 2.00 TB
Allocatable yes (but full)
...

My question is: should I be concerned about the "not usable 2.00 TB" part?

Thanks,

p.s. kernel is 2.6.9

Yes.
It's probably an indication you're using an old version of the lvm tools that doesn't support large devices properly: upgrade!
IIRC unpatched 2.6.9 also has data corruption issues with large devices.

Ok. After upgrading the lvm2 tools, it now shows "not usable 0". That makes me feel a bit better. Thanks for the advice.
