>Description:
CCD devices are created automatically at boot if /etc/ccd.conf exists as per
/etc/defaults/rc.conf. If a CCD component device resides on a raidframed
device and is not manually unconfigured prior to shutdown, the raid parity
status will always be dirty after the system boots.
>How-To-Repeat:
Configure a CCD with a component device that resides on a raidset with clean
parity. Leave it configured and reboot. Parity is now dirty.
>Fix:
Alter /etc/rc.d/ccd to unconfigure CCD devices at shutdown. Since the system
default is to automatically configure CCDs at startup, should they not be
automatically unconfigured at shutdown? The following patch from 3.1 does
this, resulting in clean raid parity across reboots.
