Re: dmraid ISW maximum partition size?

So I now notice that the sector I ended up using was one less than what 
was reported by 'dmraid -s':

size   : 1953519872

But it looks like fdisk was reading whatever 'dmraid -b' was getting:
/dev/dm-0:   1953519880 total, "N/A"

because it kept shooting for 1953519879
