I was under the impression that XFS was officially supported by Red Hat
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).
