When you start +the first server, the storage pool consists of that server alone. To add +additional storage servers to the storage pool, you can use the probe +command from a storage server that is already trusted. + +> **Note** +> +> Do not self-probe the first server/localhost. + +The GlusterFS service must be running on all storage servers that you +want to add to the storage pool. See ? for more information. + +Adding Servers to Trusted Storage Pool +====================================== + +To create a trusted storage pool, add servers to the trusted storage +pool + +1. The hostnames used to create the storage pool must be resolvable by + DNS. + + To add a server to the storage pool: + + `# gluster peer probe ` + + For example, to create a trusted storage pool of four servers, add + three servers to the storage pool from server1: + + # gluster peer probe server2 + Probe successful + + # gluster peer probe server3 + Probe successful + + # gluster peer probe server4 + Probe successful + +2.
