Sure, it's a rounding error. As I mentioned before, Vinum uses 131.5 kB (265 sectors) at the beginning of each drive for config information. You can't put subdisks in this area. You've specified sizes in MB, which is a bad idea, because you can end up wasting up to 1 MB space. In this particular case, you have 24405 MB and 240 additional sectors, not quite enough. In the case of the other drives, the space left over was enough. You could have specified the size of the subdisk as 0 (use the largest chunk available) or as 49981415 sectors (the size of the drive - 265).
