适用于

  • NetApp Astra Trident
  • 第三方备份解决方案

问题

  • 备份操作后,通过 Trident 为 Kubernetes 持久卷 (PV) 创建的快照未按预期删除。
  • 外部备份工具日志显示快照删除请求,但 Trident 返回错误,例如:

level=error msg="Unable to delete snapshot from backend." error="snapshot ... is busy"
level=error msg="GRPC error: rpc error: code=Unknown desc=snapshot ... is busy"
level=info msg="Began splitting clone from snapshot."

  • 外部工具备份后,存储上仍存在离线克隆及其相关快照。
