Well, these are mostly xen volumes with xvda. It's indeed the difference in physical extent. I can check the size of the PE with vgdisplay. Most vg's have 4MB, but the ones on small disks have 32MB (which is a bit surprising, I would expect the opposite). Then I can check with lvdisplay the actual number of extents and multiply that with the PE size. Gives me a difference of 4 MB. So, I better set the PE size on small disks in the future. And for existing volumes I can use -l instead of -L which sets the size in physical extents and not in bytes.
