Hello,
my setup is:
1 master
1 synchronous slave (up and running)
2 asynchronous slave (up and running)
Now I'm setting up asynchronous slave: first step of this setup is
pg_basebackup connecting to master.
Indirections are because it is encapsulated in a script. This script is
aimed to serve for automated replication recovery. This script is
launched by crm_mon -d daemon.
You are right to check without indirections: now I tried to run the
command directly from command line without variables- it works fine...
This means: no problem in pg_basebackup itself
but some problem in environment of process launched from crm_mon daemon.
Thanks for your hint (remove indirections). Pg_basebackup works fine
when launched from command-line..
Unfortenutely I have still no clue how to solve the issue- su works. I
Is the su - even necessary?
pg_basebackup is a Postgres client program you can specify the user you
want it to connect to using -U.
Or do you need the script to run as postgres in order to get permissions
on wherever you are creating the backup directory?
have to find out why pg_basebackup cannot fork when launched from crm_mon.
I assume crm_mon is this:
http://linux.die.net/man/8/crm_mon
from Pacemaker.
I do not use Pacemaker, but I am pretty sure that running what is a
monitoring program in daemon mode and then shelling out to another
program is not workable. The docs seem to bear this out:
