LVM1 does not support extending lun size.

did you partition the lun or are you using a whole device?
in the former case you can add a second partition, in the latter your
only chance is to reduce the lun again and assign the space as a new
lun, iirc you should be able to allocate more than one lun from the same disk group. i
am not that sure about reducing.
Watch out for the maximum number of sd devices in the kernel which is probably limited to 
40 (CONFIG_SD_EXTRA_DEVS)
