The ndbinfo arbitrator_validity_detail Table

The arbitrator_validity_detail table shows the view that each data node in the cluster has of the arbitrator. It is a subset of the membership table.

The arbitrator_validity_detail table contains the following columns:

  • node_id

    This node's node ID

  • arbitrator

    Node ID of arbitrator

  • arb_ticket

    Internal identifier used to track arbitration

  • arb_connected

    Whether this node is connected to the arbitrator; either of Yes or No

  • arb_state

    Arbitration state


The node ID is the same as that reported by ndb_mgm -e "SHOW".

All nodes should show the same arbitrator and arb_ticket values as well as the same arb_state value. Possible arb_state values are ARBIT_NULL, ARBIT_INIT, ARBIT_FIND, ARBIT_PREP1, ARBIT_PREP2, ARBIT_START, ARBIT_RUN, ARBIT_CHOOSE, ARBIT_CRASH, and UNKNOWN.

arb_connected shows whether the current node is connected to the arbitrator.
