Hi!
Thanks for pointing out pg_basebackup
The issue I'm facing now is about missing WAL files.
What i'm doing:
# su postgres -c 'pg_basebackup -D /var/lib/postgresql/9.1/main/ -x -h master -U sa_rep' ; service postgresql start
The idea is to call "postgresql start" as soon as pg_basebackup ends.
But I'm getting the following error:
FATAL: could not receive data from WAL stream: FATAL: requested WAL segment XXXXXXX has already been removed
Shoud I just increase 'wal_keep_segments' ?
If I do so, do I need do restart the master or just a reload will do it?
Thanks!
Gabriel

To:
pgsql-general@postgresql.orgGabriel you are thinking this in the correct way, but its really :
pg_basebackup -D <your data dir> --write-recovery-conf --progress --xlog-method=stream -h <your primary db server>
then you just edit recovery.conf (if needed), tweak postgersql.conf (if needed) and start the standby .

What you're looking for is pg_basebackup with - - xlog=stream, I guess.

Hi all,
I've been searching for a way to initialize a new Hot Standby node with Streaming Replication withou the need for stop or even restarting the master.
Of course the master is already with the needed SR configs.
I know I have to use pg_start_backup/pg_stop_backup, but i'd like some tips, or a link to some tutorial, with the order of the steps.
I assume will be something like:
- configure Slave for SR
- pg_start_backup()
- rsync PGDATA to slave
- start PG on the slave
- pg_stop_backup()
Anything i'm thinking wrong?
Thanks in advance,
Gabriel
