      Hi Raghavendra,
        Thanks for looking into this. Attached are the log files
          from the 3 peers. The glusterfs server is running on "Beauty".
           All 3 peers mount the native gluster client on /home. Each
          peer has a direct connection to each other, addressable via
          the /etc/hosts file. 
        

        Note that I do not see any new output in the log when this
          error occurs.  Also note that I tried to replicate this issue
          on Ubuntu 14.04 with a single brick and could not replicate
          it. 
        

        Below is some more output that might help.
        Thanks!
        Dave

    Hi Dave,

    
    Was rebalance running when you did above operations?

                          Hi All,
                            After a recent update to gluster 3.5 we
                              are having some issues renaming files when
                              root squashing is enabled and the folder
                              group permissions are not set to write. 
                            

                            For example if I create a folder with
                              the following permissions
                            $
                                mkdir test
                            $
                                chmod g-w test
                            $
                                ls -l 
                            
                              drwxr-xr-x
                                   2 dave dave  22 Jul 14 17:16 test
                            
                            
                            When I create a file within
                              this folder, and try to rename it I get a
                              file permissions error. 
                            

                            $
                                cd test
                            $
                                touch asdf
                            $
                                mv asdf asdf2
                            
                              mv:
                                  cannot move ‘asdf’ to ‘asdf2’:
                                  Permission denied
                            
                            
                            A strace on the mv command reveals the
                              rename system call fails with:
                            
                              rename("asdf",

                                  "asdf2") = -1 EACCES (Permission
                                  denied)
                            
                            
                            However I can copy the file and delete
                              the old one fine. 
                            

                            If I either disable gluster root
                              squashing, or change the test_dir folder
                              group permission to write then I can
                              rename the file without any problems.
                            

                            System details are:

                            
                            Arch linux
                            System umask is set to 002

                            
                            Distributed volume, 3 peers, 1 brick
                              per peer. 
                            

                            Any help is much appreciated!

              Hi Dave,

              
              Can you please provide the brick and client log files?
              Which client you were using? fuse or nfs?

              
              Regards,
