clustergroup addexternal

Imports an external NFS server or an external s3 server into a cluster group/global namespace.

The addexternal command adds an external NFS server or an external s3 server to the cluster group, thereby making it part of the NFS/S3 global namespace.

NOTE An external NFS server is a network file server hosted on a remote network, typically in a different physical location.

Along with Data Fabric cluster entries, NFSv4 clients see a unified directory space across servers hosted from different locations. Data Fabric data can be copied to or transferred to an external NFS server, so that it is shareable across the clusters in the cluster group.

To view external NFS server details by using the maprcli, see clustergroup get cgtable. To remove the external NFS server from the cluster group by using maprcli, see clustergroup remove cluster.

Parameters

Parameter Description

type

(Required) Use nfs to add an external NFS server. Use s3 to add external S3 server.
externalservername (Required) Name of the external NFS server/S3 server to display on the global namespace.
ips

(Conditionally Required) Required for NFS and Generic S3 servers.

List of one or more IP addresses. An NFS server with multiple network interface controllers (NIC) is identifiable by more than one IP address or hostname. Use comma as the separator, when you are specifying multiple IP addresses for the parameter.

accesskey (Conditionally Required) Required for S3 servers. The access key for the external AWS/generic S3 server.
NOTE Enclose the accesskey parameter in quotes.
secretkey (Conditionally Required) Required for AWS S3 servers. The secret key for the external AWS S3 server.
NOTE Enclose the secretkey parameter in quotes.
awswebidrolearn AWS web-identity role ARN for STS-based access. For more information about STS, see Integrating the AWS Security Token Service (STS) with Data Fabric in the as-a-service documentation.
s3vendor (Conditionally Required) Required for S3 servers. Type of S3 vendor. Use the value AWS while adding the AWS S3 server. For other S3 vendors, use the value generic.
awsregion (Conditionally Required) Required for AWS S3 servers. AWS region for the buckets that contain your data.
gcpregion GCP region for the buckets that contain your data. This field is applicable to GCP S3 server only.
force (Optional) Pass the force parameter to skip checking the external server IPs. The parameter does not require a value to be specified.
s3usetlsencryption (Optional) The field is applicable to generic S3 server import. This is a flag indicating if TLS encryption is to be used for the external S3 server. The default value for the flag is true. The HTTPS protocol relies on TLS encryption for secure communication.
s3serverport (Optional) The port number for the generic S3 server at which the communication with Data Fabric must happen.The default value is 9000.
s3servercertfile (Conditionally Required) Required for S3 servers. The S3 server security certificate content. This is applicable if the communication is to happen over the HTTPS protocol.
s3servercertfilepath (Conditionally Required) Required for S3 servers. The file path of the S3 server security certificate. This is applicable if the communication is to happen over the HTTPS protocol.
s3servertransferproto (Optional) The protocol to use to transfer external S3 server data over the Internet. https and http are the allowed valid values. The default value is https.
