Before removing a datanode, you should drop the datanode from tables before you drop the datanode.   You can do this with ALTER TALBE … DELETE NODE as seen in http://postgres-xc.sourceforge.net/docs/1_1/sql-altertable.html.   This will extract all the rows from the node and redistribute them (as well as others) to the new set of nodes.

List of the nodes where a table is distributed/replicated in pgxc_class.

I use pgxc_ctl.

My configuration is:

Node A: 1 gtm master
Node B: 1 gtm_proxy, 1 coordinator, 1 datanode
Node C: 1 gtm_proxy, 1 coordinator, 1 datanode
Node D: 1 gtm slave

First I stopped coordinator and data node from Node C. Then I executed pgxc_ctl remove datanode.... and pgxc_ctl remove coordinator... were ok. But I got "Failed to get pooled connections" message when I tried an insert or update in Node B. I also ran pgxc_pool_reload and restarted the cluster. If I run "SELECT * FROM pgxc_node" in Node B I only have one coordinator and one data node.

The inserts and update commands was ran in a DISTRIBUTE BY REPLICATION table.

Did you change your cluster configuration?   Are you using pgxc_ctl or doing configuration/operation manually?

They help to see what’s going on.

Thank you;

Hi. I dropped a coordinator node and a data node from a cluster, but when i try to make an insert or update I have a "Failed to get pooled connections" message. I executed pgxc_pool_reload() but it didn't work. What can I do? I use pgxc 1.1.
