适用于

  • NetApp ONTAP
  • SnapMirror (XDP)

回答

  • SnapMirror (XDP) 在复制期间保留 inode ID。
  • 卷内文件的 inode ID 在源卷和目标卷之间保持不变。

追加信息

  • 在 SnapMirror 中断之后:
    • 目标卷变为读写,并被分配新的卷 UUID (FSID)。
    • 这会导致设备标识符(st_dev)从 NFS 客户端角度发生变化。
  • NFS 上的文件标识: 
    • 身份文件的组合:
      • inode 编号 (st_ino)
      • 设备编号 (st_dev
    • 即使 inode 编号保持不变, st_dev 中的更改也会导致文件被识别为不同的文件。
