I have a 10x2 distributed replica volume running gluster3.8.Each of my bricks is about 60TB in size.

I will make sure the replica to the larger brick will match in size.Will gluster place more files on the larger bricks? Or will I have wasted space?
Yes, it will. Gluster will use the sizes of the bricks when calculating the layout distribution if cluster.weighted-rebalance is enabled.
There was a bug [1] which was fixed in 3.8.5 so anything newer than that should work.
On a different note, I am looking into improving Gluster documentation so where would you like to see this information in the guides?

In other words will the 80TB new bricks ever exceed 60TB?-Mark
