I think you have to ask device mapper folks how to tell how big

I've attached a little program which can be used to dump out
what the device driver reports its size as. Just give it the
lvm device as its first argument.
Bingo...log appears below:
I extended an lvm partition, and the size reported was not updated until
the partition was unmounted. How should I proceed from here? Would you
like me to report it to somebody in charge of the dev-mapper stuff? I'm
skipping the kernel patch you attached for the moment since I'm not
running into that bug. Thanks much.
