      i check the trusted.gfid xattr for luo  on all bricks:

      thanks .

      
    Could you verify the same for the parent directory of luo ('video')
    as well?

    Also, try  setting the client-log-level to DEBUG and see if you find
    anything in the debug messages of the mount log when you  "ls  /videos_store/video/"
        from that client.

        
        Thanks,

        Ravi

          hi all

           
          I've just
            had an interesting issue with
            our gluster storage:

            
            Folder disappeared on the mount point , but exists
              on bricks.

              
              e.g:   

              
                   mount point       /videos_store

                   subdirectory   "video/luo"     is exists on all
              bricks. 

                   when   "ls  /videos_store/video/"  
              the  "luo" was  disappeared. on the mount point 

                   but  when  "ls  /videos_store/video/luo/"  i can
              see all files on the "luo".

                  
              i had saw all logs. but didn't  find anything useful.

            
              I've done the
                following:

            
            1 . heal full

              2.  mv /videos_store/video/luo/ to
                    /tmp;  then mkdir  /videos_store/video/luo/

                    3. mount volume to another point : /videos_store2  .
                    

                    4. mount volume on  another server.
        
        
        Can you check if the trusted.gfid xattr for luo exists on all
        bricks and that the gfid symlink inside the .glusterfs directory
        points to luo on all of them?

        -Ravi

        
          but The
                    problem is still.
          Versions:

            * GlusterFS v3.6.1

            * centos 6.6 

              *Distributed-Replicate  replica *2 

            
          thanks.
