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 Use nfs to add an external NFS server. Use s3 to add an external S3 server.
externalservername Name of the external NFS server or S3 server to display on the global namespace.
ips List of one or more IP addresses. An NFS server with multiple network interface controllers (NIC) is identifiable with more than one IP addresses or hostnames. Use comma as the separator, when you are specifying multiple IP addresses for the parameter.

accesskey The access key for the external AWS/generic S3 server.
NOTE Enclose the accesskey parameter in quotes.
secretkey The secret key for external S3 server. This field is applicable to AWS S3 server only.
NOTE Enclose the secretkey parameter in quotes.
s3vendor Type of S3 vendor. Use the value, AWS while adding AWS S3 server. For GCP use the value GCP. For other S3 vendor, use the value, generic.
awsregion AWS region for the buckets that contain your data. This field is applicable to AWS S3 server only.
force When the force parameter is mentioned in the command, external server ips checking is skipped. The parameter does not require a value to be specified.
s3usetlsencryption 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. The default value for the flag is true. The HTTPS protocol relies on TLS encryption for secure communication.
s3serverport The port number for the generic S3 server at which the communication with Data Fabric must happen. This is an optional parameter. The default value is 9000.
s3servercertfile The S3 server security certificate content. This is applicable if the communication is to happen over the HTTPS protocol.
s3servercertfilepath The file path of the S3 server security certificate. This is applicable if the communication is to happen over the HTTPS protocol.
s3servertransferproto The protocol to use to transfer external S3 server data over the internet. https and http are the allowed valid values. This is an optional parameter. The default value is https.

Example

Add or import external NFS server having name extnfs and associated IP address as 10.163.161.123.
maprcli clustergroup addexternal -type nfs -externalservername extnfs -ips 10.163.161.123
Add or import external AWS S3 server having name awsus1 and AWS region us-west-1.
maprcli clustergroup addexternal -type s3 -externalservername awsus1 -accesskey "<access-key>" -secretkey "<secret-key>" -s3vendor AWS -awsregion us-west-1
Add or import external Scality server having name extscalityserver.
maprcli clustergroup addexternal -type s3 -externalservername extscalityserver -ips <scality server ip> -accesskey <access-key> -secretkey <secret-key> -s3vendor Generic  -s3serverport 443 -s3servercertfilepath <file path for server certificate >
Add or import external Vast server having name extvastserver.
maprcli clustergroup addexternal -type s3 -externalservername extvastserver -ips <vast server ip> -accesskey <access-key> -secretkey <secret-key> -s3vendor Generic  -s3serverport <portnumber> -s3servercertfile <server certificate content>
