I am getting the message that "Host is > unreachable" This option allows connecting *from* that IP-address to the volume. It is not an option that automatically configures a virtual ip-address for the trusted storage pool of your Gluster servers. > I need this ip address reachable so that I can connect my application which > needs to use this shared ip to connect to cluster. You would need to use a cluster manager that handles IP-addresses and their relocation on failure. Or a load-balancer that redirects the IP-address to the actual servers. An other option is to use the "backup-volfile-servers" or "backupvolfile-server" mount option. That way you an specify a fall-back server during the mount process. After the mounting, the client will talk to all the bricks in the volume directly, and not use the virtual IP-address anymore. HTH, Niels
