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 following table provides information about the columns in
the arbitrator_validity_detail table. For
each column, the table shows the name, data type, and a brief
description. Additional information can be found in the notes
following the table.
| Column Name | Type | Description |
|---|---|---|
node_id | integer | This node's node ID |
arbitrator | integer | Node ID of arbitrator |
arb_ticket | string | Internal identifier used to track arbitration |
arb_connected | Yes or No | Whether this node is connected to the arbitrator |
arb_state | Enumeration (see text) | 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.
