At work I have 16 SAS disks. They are setup with 12 in a RAID-10, 2 in a RAID-1 and 2 hot spares. The OS, /var/log, and postgres base go in the RAID-1. I then create a new data directory on the RAID-10, shut down pgsql, copy the base directory over to the RAID-10 and replace the base dir in the pg data directory with a link to the RAID-10's base directory and restart postgres. So, my pg_xlog and all OS and logging stuff goes on the RAID-10 and the main store for the db goes on the RAID-10. -- Sent via pgsql-performance mailing list (pgsql-performance@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
