Hi all,

Does anybody know why unlike so many Linux distros (Fedora, Ubuntu, OpenSUSE) CentOS does not come with XFS support by default but rather requires custom modifications after the install in order for you to be able to support XFS on your CentOS machine? Just seems a little odd given how much CentOS is oriented to be used as a server OS.

Thanks.

I've always thought that Centos follows RHEL exactly, cuz it is made from there source.

I think this is better asked of RHEL.

If Centos were to deviate from the RHEL dev path, then ity may no longer be Centos.

Am I wrong? _______________________________________________ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Good points. OK, then: why does RHEL not support XFS straight out of the box? :)

Boris.

i suspect you would be more likely to receive a meaningful answer from one of these sources:

https://listman.redhat.com/mailman/listinfo/rhelv5-list https://listman.redhat.com/mailman/listinfo/rhelv6-beta-list

in addition, this bugzilla entry (https://bugzilla.redhat.com/show_bug.cgi?id=213744#c10) suggests that you can contact Eric Sandeen at RH for further information about XFS in RHEL.

FYI, XFS should be fully supported in RHEL6 and at some point in RHEL5 (I believe it's "layered" right now). The kernel supports it, but the userspace tools must be retrieved separately from a special channel or through support.

Red Hat had to hire an XFS engineer so they could properly support it.

AFAIK, XFS kernel, modules and utils are available in CentOSPlus[1] repo

This is not correct anymore. The kernel module is in the normal kernel (atleast in 5.4 and 5.5) and the xfsprogs package is in CentOS-extras.

Note that XFS is not available for i386 since it has problems with 4K kernel stacks (in some situations).
