Hi guys,
I got one master and two slaves.
- slave01 = replication from master - working fine
- slave02 = server is configured to delay for 345600 seconds (4 days).
The issue is on the slave02 server
*Recovery.conf:*
restore_command = 'exec nice -n 19 ionice -c 2 -n 7 ../../bin/segment.sh
"../wal_archive/%f" "%p" 345600'
At about 10 days ago, I had an issue with my MASTER, and the server had to
be restarted.
*PROBLEM:*
The replication on the slave02 server is not working. When looking the
logs, I see:
WAL segment `../wal_archive/00000002000011E800000012` not found
I tried to copy manually that file, from my backups, then I get another
error:
Archived WAL segment `../wal_archive/00000002000011E800000012` is
newer than the configured delay (345600 seconds)
So it seems the database hasn't been replicated since MAY 17:
*on slave02 server:*
ls -la /var/lib/pgsql/9.2/wal_archive:
postgres postgres 16777216 May 17 18:16 00000002000011E80000000F
postgres postgres 16777216 May 17 18:18 00000002000011E800000010
postgres postgres 16777216 May 17 18:18 00000002000011E800000011
- Is there anything I can do to solve the problem? Without having to syn
all the DATABASE again?

This message is presumably generated by your "segment.sh" script. I'd
guess the file you copied is ending up with a very recent timestamp
which is causing it to be rejected by the script.

Guessing again - you want to be shipping the logs to the standby, but for
some reason they're not arriving in that directory. Is the
archive_command on the master working correctly? Are there any
errors in the log on the master?

Hi guys,
So... My servers are:
1 master
2 slaves (streaming replication)
1 backup server (replication using WAL FILES)
The backup server is not updated... it seems the WAL ARCHIVES have failed
and the server is not updated.
The error that I see on the pg_log:
WAL segment `../wal_archive/00000002000011E800000012` not found
Question:
Can I make the server be replicated by using streaming replication, so the
server would be updated.. and then I go back to the WAL ARCHIVE?
We use WAL ARCHIVE because we keep it 4 days old:
restore_command = 'exec nice -n 19 ionice -c 2 -n 7 ../../bin/segment.sh
> "../wal_archive/%f" "%p" 345600'
Thanks

*Current recovery.conf:*
#primary_conninfo = 'host= port=5432 user=replicator application_name='
restore_command = 'exec nice -n 19 ionice -c 2 -n 7 ../../bin/restore.bash
"../wal_archive/%f" "%p" 345600'
*New recovery.conf (To set streaming replication on):*
primary_conninfo = 'host=mymasterserver port=5432 user=replicator
application_name='
restore_command = 'exec nice -n 19 ionice -c 2 -n 7 ../../bin/restore.bash
"../wal_archive/%f" "%p"'
By doing that, I'd active streaming replication on my backup server.
After the database be updated, I can go backup to the replication by wal
files ?

Can I update the database just by setting the server as slave using
streaming replication?
Or I have to re-sync all the data folder and then set it as slave with
streaming replication?

If you are replaying WALs continuously without any issues, then, you can
just add *standby_mode='on'* and then, restart the standby database, that
should do.
