If this process is implemented, it does not seem to work well.
I run multiple nodes started around the same time, on very similar hardware. Some nodes were out of space and being migrated to new drives when eu-north appeared, while others completed the migration earlier. Now the nodes that were out of space are sitting at around 30 audits and almost 0 traffic, while nodes that had space have more than 3000 audits and the data gets uploaded there.
