Or maybe you have 0.90 metadata and a kernel earlier than 3.1 that imposed some limits, but I think that allows up-to 2GB, not upto 1, so that can't be the problem. Maybe you can just for i in /sys/block/md1/md/dev-* do echo 0 > $i/size done and try again. '0' means 'max' in this context. NeilBrown
