Re: Wal files being delayed - Pgsql 9.2 - Mailing list pgsql-general

Hi guys,

My current scenario is:

master01 - Postgres 9.2 master DB

slave01 - Postgres 9.2 streaming replication + wal_files slave server for read-only queries

slave02 - Postgres 9.2 streaming replication + wal_files slave server @ AWS

master01 sends wal_files to both slaves via ssh.

On the master:

select * from pg_current_xlog_location();

 pg_current_xlog_location 

--------------------------

 1A7C/14AEB2C0

(1 row)

On the slaves:

ls -ltr /var/lib/pgsql/archive/

-rw------- 1 postgres postgres 16777216 Nov 14 01:21 0000000200001A7A000000F9

As you can see, the last wal_files on the slaves isn't the 0000000200001A7C* ones. I think the SSH delivery is being delayed. Not sure why tho.

How can I see how many files are behind?
