Thanks to Patrick Ruckstuhl for the "me too" response. Surely this must
be a problem for other gluster users too.
I didn't bother trying to find Patrick's past messages since I vaguely
recall reading them previously and the gluster mailing list archive is
not easily searchable as far as I know.
Anyway, what Patrick said below was enough for me to come up with a
procedure for getting us out of this mess. I wrote a little script to
walk through the directory trees on the various local filesystems that
comprise the nufa volume, find files that do not exist in the nufa
volume, and run a mv command for each of those files. As Patrick said,
for each of these mv commands I got a "file exists" response and then
the file was visible in the gluster nufa volume.
Other than what I've done with this script, is there any more automated
way of keeping a gluster nufa volume from getting into this state or
repairing it when it does?
I assume that the only way this can happen is when files are copied to
a subvolume filesystem instead of to the nufa volume. Is that correct?
Patrick, does that agree with your experience?

Hi,
We're using gluster-2.0.1 and a nufa volume comprised of thirteen
subvolumes across thirteen hosts.
We've found today that there are some files in the local filesystem
associated with the subvolume from one of the hosts that are not
being seen in the nufa volume on any gluster client.
I don't know how or when this happened, but now we have to do some
work to get this gluster volume back into a sane state.
Is there a recommended procedure for fixing this particular problem?
That is, making all files that are found in all subvolume filesystems
be seen within the gluster nufa volume?
That looks exactly like the same problem I have. In my case it results
in a "Can not move, file exists"
(See my earlier report for details including config and setup)
