Hi there Try adapting the below snippet for your environment. I currently have a script that contains this which I use to 'start again from square one' slonik <_EOF_ cluster name = $CLUSTER; node 1 admin conninfo = 'dbname=$DBNAME1 host=$HOST1 user=$SLONY_USER'; node 2 admin conninfo = 'dbname=$DBNAME2 host=$HOST2 user=$SLONY_USER'; uninstall node ( id = 1 ); uninstall node ( id = 2 ); _EOF_ -----Original Message----- From: slony1-general-bounces at gborg.postgresql.org [mailto:slony1-general-bounces at gborg.postgresql.org] On Behalf Of St?phane P?trot Sent: 15 June 2005 10:43 To: slony1-general at gborg.postgresql.org Subject: [Slony1-general] ERROR: namespace "_cluster" already exists indatabase of node 1 Hello, I have run once the slony_setup.sh script that configures nodes. For me it looks like (the begining of script): #!/bin/sh PGBINDIR=/usr/lib/postgresql /bin export PGBINDIR PATH="$PGBINDIR:$PATH" export PATH slonik <<_EOF_ # ---- define asterix_node 1; define obelix_node 2; define idefix_node 3; # ---- # This defines which namespace the replication system uses # ---- cluster name = $CLUSTERNAME; # ---- # Admin conninfo's are used by the slonik program to connect # to the node databases. So these are the PQconnectdb arguments # that connect from the administrators workstation (where # slonik is executed). # first drop the create nodes # ---- #drop node ( id = @asterix_node); #drop node (id = @obelix_node); #drop node (id = @idefix_node); node 1 admin conninfo = 'dbname=$MASTERDBNAME host=$MLOCALE user=$REPLICATIONUSER'; #node @obelix_node admin conninfo = 'dbname=$SLAVEDBNAME host=$MDISTANTE user=$REPLICATIONUSER'; node 3 admin conninfo = 'dbname=$SLAVEDBNAME host=$MDISTANTE2 user=$REPLICATIONUSER'; # ---- # Initialize the first node. The id must be 1. # This creates the schema "_test1" containing all replication # system specific database objects. # ---- init cluster ( id = @asterix_node, comment = 'Master Node 1' ); [...] Then I had an error about primary_key that was not found. After making correction, I try to run the script again, but I got the error : >> namespace "_cluster" already exists in database of node 1 Then I have commented out the line init cluster ( id = @asterix_node, comment = 'Master Node 1' ); and add the lines "drop node (id=@asterix_node);..." but I got another error : <stdin>:18: ERROR: syntax error at or near drop Could you please tell me how to re-initialize the whole process (cluster, node definitions, etc...) ? I was looking for some tables dealing about slony (table like sl_node) but I was not able to find it. Where are they? Thanks...
