If I'm reading right, did you run the drop node op at some point on node 1 and see it succeed? If it did, the sl_node table on each other node in the cluster (save perhaps node 3) should show it gone. If that's the case, your cluster is fine and you can just run 'DROP SCHEMA mycluster CASCADE' on node 3 and then retry your store node script.

On the main db, I run the following script: cluster name = slony_cluster; node 1 admin conninfo = 'dbname = dbNAME host = localhost user = slonyuser password = slonPASS port = 5432'; node 3 admin conninfo = 'dbname = dbNAME host = 172.16.10.4 user = slonyuser password = slonPASS port = 5432'; DROP NODE ( ID = 3, EVENT NODE = 1 ); I open pdadmin on the main db and I don't see node 3 anymore. However, when I open pgadmin on the replicated db, I still see node 3. The replicated db is the one associated with node 3. I run the above script again on the replicated db but get the following error: C:\Program Files\PostgreSQL\9.3\bin>slonik drop.txt debug: waiting for 3,5000000004 on 1 drop.txt:4: PGRES_FATAL_ERROR lock table "_slony_securithor2".sl_event_lock, "_s lony_cluster".sl_config_lock;select "_slony_securithor2".dropNode(ARRAY[3]); - ERROR: Slony-I: DROP_NODE cannot initiate on the dropped node Now I need to setup another node which must have id=3. I run a script on the main db(the one pgadmin does not show a node 3). The following is the script that I used to setup the node and the error that I get: cluster name = slony_cluster; node 1 admin conninfo = 'dbname = dbNAME host = localhost user = slonyuser password = slonPASS port = 5432'; node 3 admin conninfo = 'dbname = dbNAME host = 172.16.10.4 user = slonyuser password = slonPASS port = 5432'; store node (id=3, comment = 'Slave node 3', event node=1); store path (server = 1, client = 3, conninfo='dbname=dbNAME host=172.16.10.3 user=slonyuser password = slonPASS port = 5432'); store path (server = 3, client = 1, conninfo='dbname=dbNAME host=172.16.10.4 user=slonyuser password = slonPASS port = 5432'); subscribe set ( id = 1, provider = 1, receiver = 3, forward = no); C:\Program Files\PostgreSQL\9.3\bin>slonik create.txt drop.txt:6: Error: namespace "_slony_cluster" already exists in database of node 3 Is there another way to drop nodes? Can I recover from this without dropping the cluster and restarting from scratch? Thanks.
