适用场景

  • ONTAP 9
  • Wafliron

问题解答

Wafliron扫描的三个阶段是:

第1阶段:挂载

  • ONTAP 挂载不一致的WAFL 文件系统。  为了加快客户端访问速度、Wafliron会限制对关键元数据的扫描。
  • 检查与该聚合中包含的每个FlexVol 卷关联的聚合元数据、可用空间元数据以及Snapshot副本的可用性。
  • 在此阶段中提供的唯一状态是一条消息,用于控制台记录 Wafliron 的开头。在此阶段无法监控进度。

第2阶段:文件系统扫描

  • 元数据会根据客户端访问情况按需进行检查、也会通过后台扫描进行检查。 
  • 由于按需扫描、用户在此阶段可能会发现延迟增加。
  • 可以监控进度

第3阶段:完成

  • 执行清理任务、例如:
    • 查找丢失的块
    • 验证已用块
    • 正在删除状态文件
    • 将文件系统标记为一致
