                    Hi Susant,

                      
                    I have installed Glusterfs in 2 machines which I
                    want to use for establishing cluster. I am using
                    CentOs 6.6. The gluster volume is set up and running
                    fine. I am manually creating the files onto the
                    mounted volume and they are replicating..

                    
                  So far looks like everything is working. Now I have
                  configured a shared ip address for reaching the
                  replicated volume by using the following command:

                  
                    gluster volume set [VOLUME] auth.allow [IP ADDRESS]
                  
                  
                This IP address is visible to me under "gluster volume
                info", but I am unable to ping this ip address. I am
                getting the message that "Host is unreachable"

                
              I need this ip address reachable so that I can connect my
              application which needs to use this shared ip to connect
              to cluster.

              
            This application is a little urgent for me. I would really
            appreciate your help..

            
          Thanks

    Hi,

    
    That command is just setting an acl for that IP to connect to the
    gluster daemon.

    
    Normally you don't need to add any IP addresses as glusterfs clients
    will know about both servers as soon as they connect to one of them.
    If you're using Samba or NFS the preferred option is to use CTDB to
    spread a pool of virtual IP addresses over the servers.

    
    Cheers

    
    Alex
