But that existing files might expand, which is why I went with a high number like 500GB. But I am still getting full bricks, frequently it's the first brick in the cluster that suddenly fills up.

> Make sure you are running 3.3.1 also on all the clients also. It is determined by the clients. I noticed there is a fix there is in 3.3.1 which is not in 3.3.0. In 3.3.0, it will try writing to the next brick which is the 1st brick, but only check if it is not 100% (completely) free. If it has 1 byte left, it will start writing to it, and that's why the 1st brick will get filled up.
