I'm assuming since it's a new RAID that you haven't created files on it yet, or at least not many. Try running "lsof +D /mnt/point" to see if there is any process looking at it. Then try running "inotifywait -rm /mnt/point" and let it run for a little while to see if you can catch some process accessing the fs. You will need to install "inotify-tools" to get that program.
Sure, should have said a bit more: The array was resync'ed, then (much) data was copied in. This was a few days ago.
$ sudo inotifywait -rm /new-raid
Setting up watches. Beware: since -r was given, this may take a while!
Watches established.
-> nothing listed for a few minutes
'lsofs' finds nothing relevant.
'lsofs +D' is likely to take too long:
$ sudo find /new-raid/ -type d|wc -l
101078
$ sudo find /new-raid/ -type f|wc -l
1445375
It is running now...
