Thanks for pointing to replication slot.
I Simulate the similar situation in dev env by remove the wal segment on
node1, when node2 keep inserting into a table, now it perfectly can move
forward to latest wal segment, but the difference situation is at
node_status.

In production node_status is i in node1 but r in node2, where on my dev
both nodes keep r , even I waited to let it may change quite long.

can I safely update the node_status directy on bdr.bdr_nodes?
