The RHEL6 beta is out, I'm running it, and I expect a straightforward upgrade path to the final release--I think I can just keep grabbing updated packages. Depending on how long your transition from test into production is, you might want to consider a similar move, putting RHEL6 onto something right now in nearly complete form and just slip in updates as it moves toward the official release. It's already better than RHEL5 at many things, even as a beta. The 2.6.18 kernel in particular is looking painfully old nowadays. -- Greg Smith 2ndQuadrant US Baltimore, MD PostgreSQL Training, Services and Support g...@2ndquadrant.com www.2ndQuadrant.us -- Sent via pgsql-performance mailing list (pgsql-performance@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance

Re: [PERFORM] File system choice for Red Hat systems
you can try Scientific Linux 5.x,it plus XFS and some other soft for HPC based on CentOS.

Thanks - yes, left to myself I would consider using Centos instead. However os choice is prescribed in this case I believe.
