Обсуждение: File system choice for Red Hat systems

I'm helping set up a Red Hat 5.5 system for Postgres. I was going to
recommend xfs for the filesystem - however it seems that xfs is
supported as a technology preview "layered product" for 5.5. This
apparently means that the xfs tools are only available via special
channels.

What are Red Hat using people choosing for a good performing filesystem?

regards

Mark

It also means that it's probably not production grade, anyway.

What's your time horizon?  RHEL6 will have full support for xfs.
On RHEL5 I really wouldn't consider anything except ext3.

Yeah, RHEL6 seems like the version we would prefer - unfortunately time
frame is the next few days. Awesome - thanks for the quick reply!

ext2 (xlogs) and ext3 (data).

For xfs, you may want to read this:

Thanks - yes RHEL6 is the version we would have liked to use I suspect!

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.

I've run PostgreSQL on XFS on CentOS for years. It works well. Make sure you
have a good battery-backed RAID controller under it (true for all
filesystems).

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