I currently have a multi-level single-disk setup with 4 machines, each with 100GB of storage. How do I modify the available storage capacity (modify the EC)? I currently have half of the space as redundancy. Is it possible to add only one more machine with the same configuration?

I only added one machine with the same configuration, but it couldn't be added to the cluster.

sudo tee /etc/default/rustfs <<EOF
RUSTFS_ACCESS_KEY=rustfsadmin
RUSTFS_SECRET_KEY=rustfsadmin
RUSTFS_VOLUMES='http://rustfs-node{1...4}:9000/data/rustfs0'
RUSTFS_ADDRESS=":9000"
RUSTFS_CONSOLE_ENABLE=true
RUSTFS_CONSOLE_ADDRESS=":9001"
RUST_LOG=error
RUSTFS_OBS_LOG_DIRECTORY="/var/logs/rustfs/"
RUSTFS_STORAGE_CLASS="STANDARD"
EOF
改为
sudo tee /etc/default/rustfs <<EOF
RUSTFS_ACCESS_KEY=rustfsadmin
RUSTFS_SECRET_KEY=rustfsadmin
RUSTFS_VOLUMES='http://rustfs-node{1...5}:9000/data/rustfs0'
RUSTFS_ADDRESS=":9000"
RUSTFS_CONSOLE_ENABLE=true
RUSTFS_CONSOLE_ADDRESS=":9001"
RUST_LOG=error
RUSTFS_OBS_LOG_DIRECTORY="/var/logs/rustfs/"
RUSTFS_STORAGE_CLASS="STANDARD"
EOF

The service starts up, but the web page displays a login failure message.

多级多盘的话，支持只添加一台同配置的机子吗？

If it's a multi-level, multi-disk system, is it possible to add only one machine with the same configuration?

[loverustfs]

1. If using a 4-node system, all 4 nodes must have identical configurations.

2. Once the EC (Extended Controller) is determined, it cannot be modified, never.

3. For a 4-node system, expansion requires adding 4, 8, or 12 servers, not just a single server.

好的，谢谢，那初次EC在什么时候确定，我看见官方文档中，环境变量文件页面没有配置的

EC is meaning for Erasure Coding or for Extended Controller ?

EC is meaning for Erasure Coding or for Extended Controller ?EC 是指纠删码（Erasure Coding）还是扩展控制器（Extended Controller）？

EC stands for Erasure Coding. Is there a way to configure this when initially starting the cluster? Is it automatically selected based on the number of nodes?

For example, if I have 4 nodes, and I want all disks to be usable, avoiding redundant disks, then…

It has a default value that at least one verification hard drive is required.
