I ran into this a while ago also, I have no explanation.

No, the file system has not been resized yet, only the
(virtual) device on which it resides has been resized.
Rebooting in and of itself won't change this.
It may be possible to reboot with init=/bin/sh, which
will not start many processes, and resize it from that
environment. You may have to manually activate the lv
before you can talk to it.
Possibly somebody else has a less drastic suggestion?
