repmgr witness register witness server repmgr witness register repmgr witness register add a witness node's information to the &repmgr; metadata repmgr witness register adds a witness server's node record to the &repmgr; metadata, and if necessary initialises the witness node by installing the &repmgr; extension and copying the &repmgr; metadata to the witness server. This command needs to be executed to enable use of the witness server with &repmgrd;. When executing repmgr witness register, database connection information for the cluster primary server must also be provided. In most cases it's only necessary to provide the primary's hostname with the -h/--host option; &repmgr; will automatically use the user and dbname values defined in the conninfo string defined in the witness node's repmgr.conf, unless these are explicitly provided as command line options. The primary server must be registered with repmgr primary register before the witness server can be registered. Execute with the --dry-run option to check what would happen without actually registering the witness server. $ repmgr -f /etc/repmgr.conf witness register -h node1 INFO: connecting to witness node "node3" (ID: 3) INFO: connecting to primary node NOTICE: attempting to install extension "repmgr" NOTICE: "repmgr" extension successfully installed INFO: witness registration complete NOTICE: witness node "node3" (ID: 3) successfully registered --dry-run Check prerequisites but don't actually register the witness -F/--force Overwrite an existing node record A witness_register event notification will be generated.
