the client usually caches data for about 30 seconds, IIRC, so one
would expect the potential for some sort of window, but unmounting and
remounting should invalidate all of the client's caches. what happens if
the client waits for "a while" -- can you see the data then? and what
happens if the client touches the file and then rereads it, maybe (lame, i
know)? but, regardless, i don't understand the unmount/remount thing at
all.
what kernel version(s) are you using?
