That would be showing much more disk write activity. Also, of course, one would expect to have been alerted by autosupport mail, etc.

Given the time of week when it was posted, this seems 99.9% certain!
I suppose that Michael has never been watching his filer early on Sunday morning before... Or was it Saturday evening carousing that resulted in a temporary loss of memory? :-)
The start and completion of raid scrubbing are recorded in /etc/messages (and on the console as well, if you haven't changed /etc/syslog.conf).
