      Hi Guys,
        

        I'm using the GlusterFS version 3.3.2.
        I have a problem that unable to delete files as below
        
          
          ---------------------
          $ cat log/d0105f.ai.hook
          hello!
          $ rm log/d0105f.ai.hook
          rm: cannot remove `log/d0105f.ai.hook': No such file or
            directory
        
        
          ---------------------
        
        
        This problem was found after add brick and rebalance.
        I don't know this problem is relate to the rebalance.
        So I checked the log in /var/log/glusterfs, and I found
          below suspicious messages.

        
          ---------------------
          $ tail /var/log/glusterfs/grid-kk.hs.log
          [2015-01-20 09:49:44.491634] W
            [client3_1-fops.c:647:client3_1_unlink_cbk]
            1-vol12-client-11: remote operation failed: No such file or
            directory
          [2015-01-20 09:49:44.491696] W
            [fuse-bridge.c:1029:fuse_unlink_cbk] 0-glusterfs-fuse:
            2982544: UNLINK() /hotchip/log/d0105f.ai.hook => -1 (No
            such file or directory)
        
        
          ---------------------
        
        
        I know above text file 'd0105f.ai.hook' exist in one
          gluster server with below command.
        
          
          ---------------------
          $ sudo getfattr -m . -n trusted.glusterfs.pathinfo
            log/d0105f.ai.hook
          trusted.glusterfs.pathinfo="(<DISTRIBUTE:vol12-dht>
          <POSIX(/export12/brick):gfs14:/export12/brick/hotchip/log/d0105f.ai.hook>)"
        
        
          $ ssh gfs14
          [@gfs14 /]$ ls
            /export12/brick/hotchip/log/d0105f.ai.hook 
          /export12/brick/rdcurve/log/d0105f.ai.book.o1441124.100
        
        
          ---------------------
        
        
        Exactly, I could find the file in the brick on the server
          'gfs14'.
        Additionally I knew two facts that if I rename the file
          name to another with 'mv' command,
        I can delete it with new file name.
        Furthermore, if I mount the volume newly, I could delete
          the file.
        

        I think this situation is strange. Is this bug or
          something?
        

        Best regards,
        K. Kondo
        

    Gluster 3.3.2 is old and not a maintained version from Gluster
    community point of view. It is likely that this issue is fixed and
    is not present current maintained versions i.e. 3.4.6 , 3.5.3 and
    3.6.1. So it would be hard to get help on this, so I will highly
    recommend you to move to a newer version i.e. 3.6.1

    
    Thanks,

    Lala
