        Unfortunately I haven't this log file but I have
          'run-gluster-shared_storage.log' and it has errors I don't
          know why.
        

        Here is the content of the
          'run-gluster-shared_storage.log':
        

    Make sure shared storage is up and running using "gluster volume
    status  gluster_shared_storage"

    
    May be the issue is related to firewalld or iptables. Try it after
    disabling them.

                    Where to find a proper file to read logs?
                      Because "/var/log/glusterfs/" has a lot of log
                      files.
                  
                
               You can  find mount logs like this : 
              "directory_mounted".log inside /var/log/glusterfs

              There is some issue in your setup...check this log and
              share it here.

                           Hello,

                            
                            I try to enable shared storage for
                            Geo-Replication but I am not sure that I do
                            it properly.

                            
                            Here is what I do:

                            # gluster volume set all
                            cluster.enable-shared-storage enable

                            volume set: success

                            
                            # mount -t glusterfs
                            127.0.0.1:gluster_shared_storage
                            /var/run/gluster/shared_storage

                            ERROR: Mount point does not exist

                            Please specify a mount point

                            Usage:

                            man 8 /sbin/mount.glusterfs

                            
                         This error means
                        /var/run/gluster/shared_storage directory
                        does NOT exists.

                        
                        But, running the  command (gluster volume set
                        all cluster.enable-shared-storage enable)

                        should carry out the mounting automatically.
                        (so, there is no need to manually mount).

                        
                        Check after running "gluster volume set all
                        cluster.enable-shared-storage enable"

                            1. gluster volume info

                             2. glusterfs process started with
                        volfile-id as gluster_shared_storage.

                        
                        Thanks,
