show-raft v5

Shows BDR Raft (consensus protocol) details.

Synopsis

Shows BDR Raft (consensus protocol) details such as Raft instance id, Raft state (leader, follower), and Raft term. If Raft is enabled at subgroup level, then that subgroup's Raft instance is also shown.

In some cases, such as network partition, output might vary based on the node to which the CLI is connected.

pgd show-raft [flags]

Examples

  Example 1 (multi-group cluster with subgroup Raft and with witness,
  logical standby, subscriber-only nodes)
  Note: Unlike data or witness node, logical standby and subscriber-only
  nodes don't have Raft voting rights (see Voting Nodes column).

  $ pgd show-raft
