XFS is a layered product option with 5.5, no longer a "Tech Preview." XFS in may be standard in 6, which was the case with GFS prior (layered in 4, then included in 5), but Red Hat does not publicly pre- announce products, so contact your Red Hat representative.
Since 2000, I have been lobbying Red Hat to add XFS as. an option to overcome limitations with Ext3, without other limitations and/or incompatibilities (which both ReiserFS and JFS had). I warned about this coming issue a full decade before most people starting running into it, let alone for stable features. I ran the SGI releases on Red Hat Linux 7.3 and 9, and only ran into the 1.0 bug with /var filesystems. I never had any issues with large data filesystems on those old, official SGI releases for 2.4. One reason I wanted to see Red Hat's support for XFS is because there are so many caveats to XFS with upstream development. I had seen a great number of other vendors/distros have issues. It takes a sponsor like Red Hat, especially now with the number of former SGI developers they employ, to keep upstream developments in-sync with XFS details. I currently have some customers migrating from Altix (Linux/IA-64) for large, statistical stores and number crunching. We're seeing excellent performance with 8+ stripe LV, 1MiB stripe size, multi-TB performance XFS filesystems, with no corruptions. If you have a need for very large filesystems, it's worth the subscription cost of the new filesystem layered option for XFS. It is also very helpful for Red Hat to gather interest. It also can't hurt to contact your Red Hat representative to see if you can try XFS and see how well it works for you. I wouldn't mention it if it isn't doing many things for my current client. Like many people, I have _avoided_ using "upstream" XFS, if it didn't come from SGI. Now that Red Hat is _commercially_ behind it, I've started to deploy it again. The results have been excellent so far for my current client's applications. -- Bryan J Smith - mailto:[email protected] http://www.linkedin.com/in/bjsmith Sent via BlackBerry from T-Mobile -----Original Message----- From: Chris Adams <[email protected]> Date: Tue, 8 Jun 2010 12:45:30 To: Red Hat Enterprise Linux 5 (Tikanga) discussion mailing-list<[email protected]> Subject: Re: [rhelv5-list] Anybody using ext4?

I've had some bad experiences with XFS (although that was with older versions, bad memories stay with you). I'm familiar with ext* (I remember when this new-fangled "second extended" filesystem first came out :-) ) and would prefer to stick with it. Also, while ext4 is an "official" Tech Preview in RHEL 5, with RHEL-provided e4fsprogs, don't the XFS utils have to be fetched from a third-party repo? -- Chris Adams <[email protected]> Systems and Network Administrator - HiWAAY Internet Services I don't speak for anybody but myself - that's enough trouble. _______________________________________________ rhelv5-list mailing list [email protected] https://www.redhat.com/mailman/listinfo/rhelv5-list _______________________________________________ rhelv5-list mailing list [email protected] https://www.redhat.com/mailman/listinfo/rhelv5-list
