Thread: [Postgres-xc-general] Postgres '-X' invalid option

Hi all.

I am testing Postgres XC for a project I am starting at my work place .
I apologize
if the following is already a known issue.

I was following the installation tutorial on the Postgres XC web site
(on Sourceforge)
and I have managed to install Postgresql XC 1.0.1 on a Debian Wheezy VM
(creating a
deb package from the sources), but when I am trying to start the
postgres instances
(using the postgres user) for the datanodes I'll get this error:

postgres: invalid option -- 'X'

I was looking under postgresql-xc-1.0.1/src/backend/tcop/postgres.c and
in fact this option
is not listed on the function process_postgres_switches(...), nor it is
mentioned in main.c,
located under postgresql-xc-1.0.1/src/backend/main.
I also tried to find this option on the main Postgresql versions
(9.1/9.0/8.4) but it seems that
there isn't any reference to a '-X' option.

According to the short tutorial on
http://postgres-xc.sourceforge.net/docs/1_0/install-short.html
this is the required procedure to start the cluster. If I try to start
the datanodes without the '-X'
option I'll get another error:

Postgres-XC: must start as either a Coordinator (--datanode) or Data
Node (--datanode)

which means, I guess, that this option has something to do with the
roles of the instances.


Thanks in advance.


Best regards,
Matteo

Hi Matteo,

Where did you get the instruction to use -X exactly? Maybe that specific
documentation is out of date.

Please use "-Z" instead of "-X".

Hi.

The tutorial I am following is here:
http://postgres-xc.sourceforge.net/docs/1_0/index.html
Since it is located on the main Postgres XC web site and the title is
"Postgres-XC 1.0.1 Documentation"
I thought it should be the most up to date documentation.

Thanks for your answer but unfortunately I get the same error with the
'-Z' option too:

postgres: invalid option -- 'Z'

and looking in the source code I can't find the '-Z' option as a command
line parameter.

I have pulled my sources directly from the git repository on GitHub:

https://github.com/postgres-xc/postgres-xc.git

so I believe I am not using some outdated version.


Best regards,
Matteo

X option is valid for versions 1.0.X as specified on the docs:
http://postgres-xc.sourceforge.net/docs/1_0/app-postgres.html
X is used to start a node as a Datanode and C as a Coordinator

On current master branch, those have been changed into more generic options
--coordinator and --datanode to avoid any future conflicts with postgres
options.

On the other hand, pg_ctl uses -Z coordinator/datanode to start a node as a
Coordinator or a Datanode.
It is specified on the docs here:
http://postgres-xc.sourceforge.net/docs/1_0/app-pg-ctl.html
However this page looks to be outdated. I am going to fix that tomorrow.

Ok, thank you Michael. Using the '--cordinator' and '--datanode' options
I was able to start my test cluster and now it's up and running :-).

May I also suggest a slightly modification on
src/backend/postmaster/postmaster.c?
At line 780, inside the #ifdef PGXC ... #endif the line

write_stderr("%s: Postgres-XC: must start as either a Coordinator
(--datanode) or Data Node (--datanode)\n" (...)

should be something like this:

write_stderr("%s: Postgres-XC: must start as either a Coordinator
(--coordinator) or Data Node (--datanode)\n" (...)

Is it right?

Best regards,
Matteo

I just committed the fix for the comment. Will take care of correcting
pg_ctl.sgmlin later.
