Thread: [Postgres-xc-general] Add new coordinator error!

Dear Sir,

I have a cluster with 3 coordinators and 3 datanodes on 3 VM, today i 
was try to added a new coordinator to the cluster, when i using command 
"psql postgres -f coordinator.sql -p 5455" to restore the backup file to 
the new coordinator.

Then i got this message :

psql:coordinator-dump.sql:105: connection to server was lost

In the log file:

Is there something i doing worng?


Thanks for your kindly reply.

  And sorry for my poor english.


Best regards.

You cannot add a coordinator in such a way.    There're many issued to be
resolved internally.   You can configure and operate whole cluster with
pgxc_ctl to get handy way to add coordinator/datanode.

I understand you have your cluster configured without pgxc_ctl.   In this
case, adding coordinator manually could be a bit complicated work.   Sorry,
I've not uploaded the detailed step to do it.

Whole steps will be found in add_coordinatorMaster() function defined in
coord_cmd.c of pgxc_ctl source code.   It will be found at contrib/pgxc_ctl
in the release material.

Please allow a bit of time to find my time to upload this information to XC
wiki.

Or, you can backup whole database with pg_dumpall, then reconfigure new xc
cluster with additional coordinator, and then restore the backup.

I supporte the error was encountered in pg_resgtore and pgxc is the owner
of postgres-XC in your pgxc_ctl.conf file.   The issue looks some (not
necessarily just one) bugs.  Can I have log files at the new coordinator?
 This may have some more information on the issue.

I checked two files.   Did you specify pgxc as a database owner?   It seems
that the role pgxc already exists when pg_restore tries to restore the role
"pgxc".    Maybe we need to control internal pg_dump to exclude such
existing superusers from the restore list, and also need to fix the crash
to move forward with the same situation.

Are you using different operating system user and XC owner name?   If then,
could you try to use the same name for these?

Okay.   I'm wondering why internal pg_restore complains pgxc already
exists.    If you do not specify pgxc in pgxc_ctl and created it manually,
newly-craeted node should not contain the role pgxc, though we have
different massage.

Could you let me know if you have any idea?

I understood the situation.   Could you let me know if pgxc is not the
operating system user name you are using?  If so, I will run the test with
this situation and see what is going to happen.   Maybe a bug (not
Postgres-XC core, but pgxc_ctl).   If pgxc is the operating system user you
are using, then there could be another cause.  Also, please let me know
your setting of pgxcUser in pgxc_ctl.conf?

I found your configuration, in terms of owner and user, is the same as my
demonstration scenario.   Then what you should do is:

1. Log in to your operating system as pgxcUser,
2. Initialize Postgres-XC cluster with "init all" command of pgxc_ctl,

Then the database user $pgxcOwner should have been created and you don't
have to worry about it.   When you add a coordinator, simply issue "add
coordinator master" command.   It should work.  If you have any other
issue, please let me know.

My pgxc_ctl demonstration scenario will be found at
https://sourceforge.net/apps/mediawiki/postgres-xc/index.php?title=PGOpen2013_Postgres_Open_2013

The configuration is with full slaves, which you can disable.   The demo
adds a datanode, not a coordinator.   I believe there's no significant
differences.

I can not just issue "add coordinator master",it alway asked me for more
here is my step:

# Deploy binaries
PGXC$ depoly all
#initialize everyting: one GTM Master, three GTM_Proxy, three
coordinator, three datanode
PGXC$ init all
....
PGXC$ Createdb pgxc
....
PGXC$ Psql
pgxc=# select * from pgxc_node; node_name | node_type | node_port |
node_host | nodeis_primary | nodeis_preferred | node_id
....
pgxc=# create table user_info_hash(id int primary key,firstname
text,lastname text,info text) distribute by hash(id);
NOTICE: CREATE TABLE / PRIMARY KEY will create implicit index
"user_info_hash_pkey" for table "user_info_hash"
CREATE TABLE
...
PGXC$ deploy node4
PGXC$ add datanode master datanode4
*ERROR: please specify the host for the datanode masetr*
PGXC$ add datanode master datanode4 node4 20008 /opt/pgxc/nodes/dn_master
*ERROR: sorry found some inconflicts in datanode master configuration.*
--------------------------------------------------------------


2.
and i found when the dump file contain table with

CREATE TABLE user_info_hash (
id integer NOT NULL,
firstname text,
lastname text,
info text
)
DISTRIBUTE BY HASH (id)
TO NODE (datanode1,datanode2,datanode3);

is alway failed to add new coordinator
but with this

CREATE TABLE user_id (
id integer NOT NULL
)
DISTRIBUTE BY HASH (id)
TO NODE (dn2,dn1,dn3);

it's sucessed to add the new coordinator to the cluster

These commands are for the initial ones.     I think you've already done that.

add command syntax will be found at http://postgres-xc.sourceforge.net/docs/1_1/pgxc-ctl.html.   Please take a look at the section F.32.12.

No.   To add a coordinator, you should have correct resource in "add" command.   The error message above indicates there are some conflict in the resource you specified with another node.   You must specify unique port number and work directory within the server.

To add a coordinator, you should issue the following command:

PGXC$ add coordinator master name host port pooler dir

When you issue this command and it is successful, your pgxc_ctl.conf will have additional line with this additional node.   Please take a look at it.  If it fails and you'd like to  restore to the previous configuration, you can edit pgxc_ctl.conf by yourself.   In this point, pgxc_ctl is still "primitive".

Sorry, i found i have already config pgxcOwner=pgxc in pxc_ctl.conf.

And i forgot to mention there's something strange about to add new coordinator,
i can’t add coord4 by "add coordinator master coord4 node4 20004 20010 /opt/pgxc/nodes/coord”

it will show me
ERROR: sorry found some inconflicts in coordinator master configuration.PGXC$

unless i add coord4 to pgxc_ctl.conf and remove it at PGXC shell
PGXC$ remove coordinator master coord4
ERROR:  PGXC Node coord4: object not defined
ERROR:  PGXC Node coord4: object not defined
ERROR:  PGXC Node coord4: object not defined

Is it normal ?

attach file is my pgxc config
