How "full" does it has to be before new files start getting written into the other bricks?
By default, min-free-disk is set to 10% and min-free-inodes is set to 5%.
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.
Yes, rebalancing is slow. I have work in progress to make it less slow by doing the fix-layout part minimally instead of for every single directory in the entire volume, and to skip the migrate-data part entirely in favor of just letting new data get placed onto new bricks. I don't know when those will make it into a release, but if you're interested you can read about the work in progress here.
