also happened in a November 5, 2004 -CURRENT as well.
>Description:
ports/sysutils/diskcheckd runs fine when gmirror is not involved so when ad0 and ad2 were standard /dev/ad0 slices, diskcheckd ran fine.  However, when the same devices are part of gmirror, the HDD light would stay on continuously solid from when diskcheckd is ran until system shutdown - 2 weeks is the longest I have experienced this.  If I stopped diskcheckd, the HDD light would go off immediately.

It is similar to:

http://www.freebsd.org/cgi/query-pr.cgi?pr=ports/115853

diskcheckd also is not logging to syslog as /var/log/messages does not show anything except I noticed in ttyv0, it will show the following a few minutes after FreeBSD completely boots:

diskcheckd[x]: reached end of /dev/ad0 with 0 errors
diskcheckd[x]: reached end of /dev/ad2 with 0 errors

>How-To-Repeat:
run diskcheckd with a system that is running gmirror.
