适用场景

  • ONTAP 9
  • CIFS
  • macOS 10.14
  • macOS 10.15.

问题解答

  • 从SMBv2开始、当删除文件或文件夹时 delete on close 、会在该文件夹上设置一个、随后关闭该文件夹时、该文件夹将从文件系统中删除
  • MacOS CIFS客户端的行为与Windows客户端不同、Windows客户端在打开以删除时需要以独占方式访问某个文件夹
  • 此行为可能会导致共享违规、从而阻止客户端删除此文件夹。

示例:

18557   2020-01-30 15:46:09.003908   172.18.24.33   172.18.20.90   SMB2   Create Request File: ...\Folder1\TestFolder

18558   2020-01-30 15:46:09.004297   172.18.20.90   172.18.24.33   SMB2   Create Response File: ...\Folder1\TestFolder

44599   2020-01-30 15:46:24.759237   172.18.24.49   172.18.20.90   SMB2   Create Request File: ...\Folder1\TestFolder;SetInfo Request FILE_INFO/SMB2_FILE_DISPOSITION_INFO;Close Request

44600   2020-01-30 15:46:24.759696   172.18.20.90   172.18.24.49   SMB2   Create Response, Error: STATUS_SHARING_VIOLATION;SetInfo Response, Error: STATUS_SHARING_VIOLATION;Close Response, Error: STATUS_SHARING_VIOLATION

  • 帧18557:客户端A打开文件以进行读取访问、并共享以进行读取、写入、删除。(此数据包跟踪不会关闭此文件。)
  • Frame 74599:Client B (客户端B)打开文件以进行删除访问、共享none (对文件的独占访问)
  • 帧44600:客户端B收到STATUS _共享_违规

追加信息

可能的临时解决策包括:

  1. 在同一共享上创建一个"待删除"文件夹
  2. 将空目录移至"待删除"并为其指定唯一名称(例如、基于客户端的主机名和日期)
  3. 尝试删除空目录
  4. 如果删除失败、则需要稍后 进行清理

备注:步骤2中的唯一名称可确保将来在同一目录名称上成功重命名。
