extended lv doesn't show correct size

Hi,
I ran lvextend on a lv to extend it from 1.1TB to 2.66TB and there where no errors given and lvdisplay shows it as 2.66TB but now it is only listed as 679.27 GB if I run lvmdiskscan is there anyway to fix this? I have tried removing and adding a few extents but that doesn't change the size.
I'll include some printouts if that can be of any help:
The lv is /dev/site/ftp and I'm running Slackware 10 with a 2.6.12.6 kernel.
Yours Sincerely
Willy Vanlid

Run with -vv and look for a line:

What does it say?
