  • 如果网格的对象数据存储处于或接近 100% 使用,StorageGRID 将拒绝 PUT 请求,直到足够的节点恢复到可写状态。
  • 在接收站点拥有足够的可写节点以满足 ILM 规则非常重要。  
    • 如果我们没有足够的节点来满足 ILM 规则,则网格可以:
      • 如果在摄取站点有 2 个可写节点,则默认为双提交摄取行为(2 个副本),这会导致对象空间消耗更快
      • 如果在摄取站点可写节点少于 2 个或 ILM 规则具有无法满足的严格摄取行为,则写入失败
        • 除非存在 1 份 ILM 规则
  • 通常在网格 100% 满之前就会看到影响,因为我们设置了阈值将节点置于只读模式,这被称为水印。
