I am using xfs on my fedora/ccrma box (kernel from atrpms), but I
haven't got down to any audio work yet - when i do I'll report my
results.

but I have no data on that. Mark Knecht documented the responses of
the
different filesystems using Benno Senoner's Latency Test program. I
have the results on my site at:

My own (totally unscientific) results are also commented on there.

you're going to rebuild use ext3 instead of ext2 for the root

What is the reason for using two different filesystems here? Is
reiserfs
more suitable for (audio) data?
Personally, I am using xfs (also journalled) for all workstations I
install, after having used it successfully on a heavy duty fileserver
for more than 2 years. It never gave me any problems, and I have done
some nasty tests.
Now, I have never run Ardour - on top of my TODO list for a looong
time
:-), so I can't say how Ardour and xfs play together, but I'd be
surprised
if there are any problems. Anyway, I would be very much interested to
hear
if others are using xfs, and how it behaves under heavy multitrack
audio
IO.
Ah, and xfs has a special "realtime" mode. From the kernel
configuration:
If you say Y here you will be able to mount and use XFS filesystems
which contain a realtime subvolume. The realtime subvolume is a
separate area of disk space where only file data is stored. The
realtime subvolume is designed to provide very deterministic
data rates suitable for media streaming applications.
which sounds very interesting. BUT!:
This feature is unsupported at this time, is not yet fully
functional, and may cause serious problems.
Serious problems... Hmm, looking at Aaron's mail, he already got
enough serious problems even without experimental xfs features...
xfs is in kernel 2.6.x, and has been included in 2.4.25 as well.
(before that, sgi provides patches)
