Re: [Postgres-xc-general] Problem with adding new datanode (ERROR: Node name datanode3 duplicate )

[Juned K. <jkh...@gm...>]

Hi Masataka, Koichi,

New datanode is successfully added and all components are running.i have
small doubt.

As i just added new datanode so , will existing database automatically
copied
on this datanode or i have to create and import it manually from another
datanode ?

As per that video, we need to just fire alter query just like :
*alter table t1 add node (datanode3);*
is that so ?

and yeah as of now i am getting Failed to get pooled connections error.
koichi=# execute direct on (datanode3) 'select * from t1';
ERROR:  Failed to get pooled connections

Please advice.
