Hi all, Please help... I have 1 master PostgreSQL and 1 standby PostgreSQL. Both servers has the same OS Linux Debian Wheezy, the same hardware. Both server hardware: CPU: 24 cores RAM: 128GB Disk-1: 800GB SAS (for OS, logs, WAL archive directory) Disk-2: 330GB SSD (for PostgreSQL data directory, except WAL archive and except pg_log) The part of the configuration are as below: checkpoint_segments = 64 checkpoint_completion_target = 0.9 default_statistics_target = 10 maintenance_work_mem = 1GB effective_cache_size = 64GB shared_buffers = 24GB work_mem = 5MB wal_buffers = 8MB wal_keep_segments = 4096 wal_level = hot_standby max_wal_senders = 10 archive_mode = on archive_command = 'cp -i %p /home/postgres/archive/master/%f' The WAL archive folder is at /home/postgres/archive/master/, right? This directory consumes around 750GB of Disk-1. Each segment in the /home/postgres/archive/master/ is 16MB each There are currently 47443 files in this folder. If I want to limit the total size use by WAL archive to around 200-400 GB, what value should I set for the wal_keep_segments, checkpoint_segments?
