repmgr node rejoin
repmgr node rejoin
Enables a dormant (stopped) node to be rejoined to the replication cluster.
Currently repmgr node rejoin can only be used to attach
a standby to the current primary, not another standby.
This can optionally use pg_rewind to re-integrate a node which has diverged
from the rest of the cluster, typically a failed primary.
The node must have been shut down cleanly; if this was not the case, it will
need to be manually started (remove any existing recovery.conf file) until
it has reached a consistent recovery point, then shut down cleanly.
Usage:
repmgr node rejoin -d '$conninfo'
where $conninfo is the conninfo string of any reachable node in the cluster.
repmgr.conf for the stopped node *must* be supplied explicitly if not
otherwise available.
repmgr node rejoin can optionally use pg_rewind to re-integrate a
node which has diverged from the rest of the cluster, typically a failed primary.
pg_rewind is available in PostgreSQL 9.5 and later.
pg_rewind *requires* that either wal_log_hints is enabled, or that
data checksums were enabled when the cluster was initialized. See the
pg_rewind documentation for details.
