Re: Removing archived wal files on Master

Thank you everyone for ther help.
I can confirm that my issue has now been resolved.

Just to recap:

* Set postgresql.conf (WAL section):
* wal_level = minimal
* archive_mode = off
* comment out the archive_command
* Restart postgresql server
* Ensure postgresql service is up and running
* Delete the folder archive folder within /var/lib/postgresql/9.3/main/

Regards,
Michael

Hi Michael,

I suspect that your DB parameters are set to default and database is not running in an archive mode as archive_mode = off , I believe PostgreSQL won't write archives when archive_mode is off and WAL archival cannot be enabled when wal_level is "minimal".

I assume the existing 200GB worth of archived wal files are old where you can verify by checking the timestamp of the Wal files and remove.

If you want to disable/enable archive_command you can simply comment/uncomment parameter and reload the server to affect but for
enabling archive_mode = on server required a restart.

Hi,
I recently acquired a legacy server. This is running Postgresql 9.3 on Ubuntu 16.04.
There is around 200GB worth of archived wal files (~12,500 files) located on /var/lib/postgresql/9.3/main/archive.
I have checked and can confirm that this is a standalone server without any Replication setup and no secondary/slave server talking to it.

Checking the /etc/postgresql/9.3/main/postgresql.conf file (write ahead log section), shows the following:
wal_level = minimal
archive_mode = off
archive_command = 'test ! -f /var/lib/postgresql/9.3/main/archive/%f && cp -i %p /var/lib/postgresql/9.3/main/archive/%f </dev/null'

Replication section shows all default values.

Could you please advice how I can cleanup all of these 200GB worth of files.
I've searched through numerous postgresql books/blogs/articles which all have very good advise on how to setup wal archiving but unfortunately not on how to disable it.

Kind regards,
Michael
