适用于

ONTAP 9

回答

  • NFS 客户端能够使用过多的存储池资源,从而导致 NFSv4 存储池资源耗尽
  • 可以对单个客户端可以使用的资源数量设置限制
  • 当客户端达到此限制并随后被阻止时,将发生 EMS Nblade.nfsV4BlockClient
    • 默认情况下不会启用客户端阻止
    • StorePool 限制控件和客户端阻止仅在 ONTAP 9.13.1 或更高版本中可用

追加信息

 NFSv4 client 10.1.1.1 has consumed the maximum store pool resources of type OpenAlloc. It is disconnected and is marked as a blocked client.

  • 如果启用了 limit-enforce,则针对每个 NFSv4 storepool 类型(Lock、Delegation、Open 和 Owner)按客户端应用配置的最大阈值。

  • 例如,Owner Maximum Threshold: 50% 意味着可以防止单个客户端占用 Owner storepool 的 50% 以上。
  • 这并不意味着所有客户端的总使用量限制为该池的 50%。
  • 换言之,该设置旨在防止任何一个客户端不成比例地消耗 storepool 资源,而不是对所有客户端施加全局 50% 的上限。
