How "full" does it has to be before new files start getting written into the other bricks? In my recent experience, I added a new brick to an existing volume while one of the existing 4 bricks was close to full. And yet I constantly get out of space error when trying to write new files. Full rebalancing was also such as slow process that it cannot keep up with new files I need to write to the volume. I am using 3.3.0-1. ... ling On 01/28/2013 01:58 PM, Alexandros Soumplis wrote: > You mention "The way this is supposed to work is that if a brick is full > then *new* files will be created on other bricks with more space.".
