我有一个8个minio节点的集群。每个节点都有一个1.6 - 1.9 TB的驱动器。节点6的可用空间不足1兆字节，而其余节点的可用空间约为200GB到1tb。是否有办法触发使用资源的再平衡?
Minio通过docker运行，下面是堆栈定义:

MinIO不执行任何再平衡。如果磁盘空间不足，它支持扩展集群(通过添加新的磁盘池)- https://docs.min.io/docs/distributed-minio-quickstart-guide.html.
然而，您的情况似乎是一个异常-可能是应用程序中的错误(可能创建同一个对象的太多版本)或MinIO中的错误-它不应该发生。如果没有更多的信息，很难确定问题所在。
