Cluster Scale-Out

#1

Dear, i need to add new nodes on my tigergraph cluster. By follow documentation, i am trying this command:
gbar expand <node_alias_1>:<ip_1>,<node_alias_1>:<ip_2>,…,<node_alias_n>:<ip_n>

but i am getting this error:

tigergraph@tigergraph-01 : ~ $ gbar expand tigergraph-04:192.168.166.216
Parse command failed, action expand not supported

How can i do to add new node ?

TigerGraph version is 3.0.5

Best regards

Hi,

Where is your cluster deployed? Which edition are you using (developer or enterprise)? How many nodes do you already have?

Hi,

In-cluster expansion requires support help. Our support reach out to collect additional information.

Hi,
Our cluster is deployed on ubuntu for test. we are using enterprise. we have 3 nodes, we want to add 1 node and to test if we can also decrease the number of nodes from 4 to 3.

Hi,
Why tigergraph document can’t give the detail to add additional nodes. We are working to do some test before deployment in production.

Hi,

This is a known issue. https://docs.tigergraph.com/faqs/release-notes-tigergraph-3.0#system-management-2

you cannot do automated cluster scale out. It needs some manual steps.That’s why, you need to follow support steps.

Thanks
