适用于

  • ONTAP 9
  • FAS/AFF
  • 反勒索软件防护 (ARP)
  • SnapLock

问题

  • Snapshot 预留使用量增长迅速,可能超过 100%。额外的部分会溢出到活动文件系统中。

  • AIQUM 引发 “Risk – Volume Snapshot Reserve Days Until Full”,例如:“设置为 7 天的 Days Until Full 阈值已被突破。在卷 Snapshot 预留达到其全部容量之前还剩 2 天。”

  • 反勒索软件保护已启用,并被怀疑是原因。但是,攻击概率为“无”。

  • Snapshot 自动删除不会释放任何空间。
