Listing CLDB Nodes

Describes how to list CLDB nodes in the HPE Ezmeral Data Fabric.

Use the nodelist cldbs command to list all the CLDB nodes for a specified cluster.

For example:
# maprcli node listcldbs -cluster my.cluster.com -json
{
	"timestamp":1529445021408,
	"timeofday":"2018-06-19 02:50:21.408 GMT-0700 PM",
	"status":"OK",
	"total":1,
	"data":[
		{
			"CLDBs":"in111-22.qa.lab,in111-24.qa.lab,in111-21.qa.lab"
		}
	]
}

Alternatively, use the maprcli node list command to find out whether a node is a CLDB node.

SSH into the node as root or the Data Fabric admin user, and issue the following command:

maprcli node list -columns svc,ip

A node is a CLDB node if the service list includes cldb as one of the services:. For example:

$ maprcli node list -columns svc,ip
hostname              service                                                                                     ip
