Hi List!
I was under the impression that XFS was officially supported by Red Hat Enterprise Linux.

During the installation i noticed that Anaconda wouldn't allow XFS as root file system. Well, that's not a big problem for me. But after installation i realized that they don't even include xfsprogs so that i could do mkfs.xfs. Well, also not a big problem, i used the latest tarball and compiled them myself.

But the big question now is: can anybody actually recommend using XFS on stock RHEL? It does feel like being just a stepchild there. On the other hand there seem be be quite a number of patches that were backported for Red Hat's kernel and it does use delaylog by default (which IIRC wasn't the default with a stock 2.6.32 Kernel).

tia,
Michael

It's an addon product and not supported as a root filesystem on RHEL 6:

A number of the XFS developers are employed by Red Hat...

And it is the only file system in RH Storage (gluster) that we support and quite popular with normal RHEL users as well.

Definitely not ignored in any way.

If you have questions about how to get it, let me know.

Regards,

Ric

Which gets you into unsupported land I'm afraid. As others mentioned, it's an add-on product in RHEL6, available w/ a separate subscription. That subscription comes with official RHEL xfsprogs, and support.

As Ric said, it's very much *not* a stepchild. :)

Thanks for your answers, it's much clearer now!

Michael

A very belated follow up, but we just announced this week that RHEL7 plans to use XFS as its default file system and will not be restricted (you can use it there for boot, root or whatever).

Thanks!

Ric
