This error message is because the way the root mount works is it keeps trying
different filesystem types until it succeeds, reiserfs is in there before XFS.
I saw someone float a patch which specified the rootfs type as a kernel boot
option, I do not know if this will make it into Linus's tree or not. Maybe
reiserfs (and XFS) should not be so chatty on a failed mount in this case.
I added Chris Mason to the cc list, he may have some input on cleaning up
failed mount output and the other reiserfs question you had.
XFS should have no problems with hardware raid, lvm works to I think, but
I am not sure performance is the best right now. The unmount stuff is mostly
the root filesystem unmount, on Irix there is no option to remount a filesstem
readonly which is the standard Linux shutdown procedure, we added code to
make this functionality in Linux, but it is not the fastest it could be (there
are some sleeps in there at the moment!).
