[linux-lvm] mirroring an LV?

I'm pulling my hair out trying to setup a mirrored logical volume.
lvconvert tells me I don't have enough free space, even though I have
hundreds of gigabytes free on both physical volumes.
Command: lvconvert -m1 /dev/vg1/iscsi_deeds_data
Insufficient suitable allocatable extents for logical volume : 10240
more required
Any ideas?
Thanks!,
Gordon
Here's the output from the lvconvert with verbose and debugging turned on:
# lvconvert -vvv -d -m1 /dev/vg1/iscsi_deeds_data
