This means that the two bricks are combined as a mirror. Anything written to one, is also written to the other. So, effectively you only have one brick worth of available space. If you want to have 550GB of space in the volume, then you need to not specify any replica counts for the volume. -- Mr. Flibble King of the Potato People
