Bring back stand By node to permanent state in Vertica

hdk0310hdk0310 Registered User

Hi,
I have a 12 node cluster in which all the 12 nodes are working fine. I did an experiment to keep a node on stand by (let's say node 12-- node_type=STANDBY and node_state=STANDBY). It worked the way I thought If one of the node is down standby node will be active. Now I wanted it to Revert it back to the original. I do not want any of the nodes in STANDBY state all should be up with NODE_TYPE=PERMANENT. But Vertica is not allowing for the same. If I do ALTER NODE (node‑name) RESET; It gives an error: [Code: 6359, SQL State: 55000] [Vertica]VJDBC ROLLBACK: Node (node-name) has not been replaced. Any help will be appreciated. Thanks - clear

    Please try the following to see if it works

    alter database reset standby;

    Hi Shruthi,

    Thanks for your response.

    This command doesn't work.
    alter database reset standby;-- It runs successfully without any error or warning but node still remains in STANDBY state. No impact on node state

    ALTER NODE RESET ;
    (6359) ROLLBACK: Node v_vertexdb_node0012 has not been replaced.

    Thanks

    Please open a support case. I think it needs catalog editing.
