Start four nodes for the first time in the virtual machine, with four disks per node:

RUSTFS_VOLUMES="http://node{1...4}:7000/data/rustfs{0...3}"

The startup is normal. Then, attempt to add:

RUSTFS_VOLUMES="http://node{1...4}:7000/data/rustfs{0...3} http://node{5...8}:7000/data/rustfs{0...3}"
