Try it. If your drive (array) is larger than 512byte*4G (4TB) linux will eat your data.
drivers/block/ll_rw_blk.c, in submit_bh() > bh->b_rsector = bh->b_blocknr * (bh->b_size >> 9);
But it shouldn't cause data corruptions: It was discussed a few months ago, and iirc LVM refuses to create too large volumes.
