Is there a way to identify files that are actively being written to a CIFS mount in Linux? I am interested in skipping those files.

My first thought would be to fine tune the find command with mmin. I am not sure if this would catch them though.

find /cifs -type f -name "*.wav" -mmin +3

I would take a look at the smbstatus command.

There you could grep for READ/WRITE locks (e.g.)

smbstatus  | grep RDWR

Add sed or awk magick to get to the file name.

  • So I should clarify that a different server is writing these files to the share – kernelpanic Feb 4 '16 at 19:06
  • you could still use smbstatus over ssh, (from the writing server): ssh <server with smb share> smbstatus | grep RDWR Of course you need to set up authentication by ssh key pair. – remote mind Feb 4 '16 at 19:12
  • I don't have access to the servers writing to the share – kernelpanic Feb 4 '16 at 20:40
