Thanks, Scott. Just to clarify you said: > 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. Is that meant to be that the pg_xlog and all OS and logging stuff go on the RAID-1 and the real database (the /var/lib/postgresql/8.3/main/base directory) goes on the RAID-10 partition? This is very helpful. Thanks for your feedback. Additionally are there any clear choices w/ regard to filesystem types? Our choices would be xfs, ext3, or ext4. Is anyone out there running ext4 on a production system? -Whit -- Sent via pgsql-performance mailing list (pgsql-performance@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
