While the volume is offline, an ls will show newfile (to me this seems
wrong) -- the
file gets renamed in the namespace volume.

When the volume is brought back online, ls will show both newfile and
oldfile, however
as newfile probably doesn't exist on any volumes, you will get an I/O
error if you try to
read it.

To me it seems that calling rename on a file that is unavailable
should fail immediately
without modifying the namespace, or the file should be `magically'
renamed later when the
volume comes back online.

This raised his doubts to such a pitch,
He fell flat into the ditch,
Not knowing how to run.
