# Rejoin the diverged master with a chosen recovery method

`POST /api/clusters/{clusterName}/actions/unsafe-rejoin/{method}`

Explicitly (re-)arms the rejoin using the operator-chosen method. Safe methods use /actions/rejoin (needs cluster-failover); destructive methods (ignore-delta-force, bootstrap-repli-ftwrl, reset-master-reslave) use /actions/unsafe-rejoin (needs cluster-failover + cluster-rejoin-unsafe). The method must match its verb.

- `method` 'flashback' | 'logical-dump' | 'logical-backup' | 'physical-backup' | 'rejoin-script' | 'ignore-delta-force' | 'bootstrap-repli-ftwrl' | 'reset-master-reslave', required

- `400` — Invalid rejoin method / wrong verb
