    Source groups, in priority order, from which to pull missing nodes.

    • transfer_to ({ resource_group: string }[]) -

    Target groups, in priority order, to which excess nodes are pushed.

    • node_filter ({ node_labels: KeyValuePair[] }) -

    Required node labels; only nodes that match all labels are admitted to the group.

    • requests ({ node_num: number }) -

      The minimum number of nodes the group must have. Missing nodes are pulled from groups listed in transfer_from.

    • transfer_to ({ resource_group: string }[]) -

      Target groups, in priority order, to which excess nodes are pushed.

    • node_filter ({ node_labels: KeyValuePair[] }) -

      Required node labels; only nodes that match all labels are admitted to the group.

  • nodes (NodeInfo[]) -

    Optional. The current member nodes of the group, with their IDs, addresses, and hostnames.

• ResStatus A ResStatus object.

  • code (number) -
