部署方式是2节点。每个节点1块盘。
节点1部署admin_cli monitor mgmtd meta storage client
节点2部署storage
启动storage_main.service后报错：
节点1 storage_main-err.log:

修改stripesize 即16就不报错了。但不清楚具体关系。
/opt/3fs/bin/admin_cli -cfg /opt/3fs/etc/admin_cli.toml "init-cluster --mgmtd /opt/3fs/etc/mgmtd_main.toml 1 1048576 16"
有的资料里还提到了group(add_group/active_group/full_group), group似乎是多个chunk的组合？ 比target粒度小？
