    Description

      Reproduce steps:

      1. prepare a lustre fs
      2. on node-1, mount lustre fs (e.g., /mnt/lustre). And nfs export the lustre fs
      3. on node-2, mount nfs exported fs from node-1 (e.g., /mnt/nfs_lustre)
      4. on node-3, copy some local files to node-2 with 'scp -p' command
      node-3# scp -p file_1 node-2://mnt/nfs_lustre/file_1
      

      Sometime the mtime of target file is not the same as source file. It is still at current time.

      node-1, 2, 3 may be one single node.

      The bug cannot be reproduced if any protocol (lustre/nfs/scp) is skipped.
