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
mynode.mycompany.net s3server,historyserver,resourcemanager,fileserver,cldb,nfs,mastgateway,hoststats,apiserver 10.163.167.210
