Checking the Connectivity of Each Node

As a tool of Greenplum, gpcheckperf is used to check the cluster performance and configuration. It also provides basic functions for checking the cluster status, including connectivity check. Perform the operations in this section on the master node.

Run the following command to check the connectivity of each node:

gpcheckperf -f /data/gpdb/all_hosts -r N -d /tmp

If data is returned, all nodes are successfully connected.
