Hi Everybody,
	I installed ccd on my system with an initial value of 16 for 
interleave. I followed the instructions in the README file:

ccdconfig -Cv 
disklabel ccd0 (just to make sure there is a valid disklabel)
newfs /dev/rccd0c
mount /dev/ccd0c /work

	Everything worked fine in the first time. However, I want to
change the interleave size in /etc/ccd.conf, but I can't. I change the
/etc/ccd.conf file and reboot. The symptons are:

	1) When I try to run ccdconfig -Cv I got the message: /dev/ccd0c:
Device Busy
	2) When I try to do a newfs /dev/rccd0c the message is:
write error: 7547151
wtfs: Invalid Argument
	3) if I mount the ccd0c device on /work and do a ls -l /work
the message Bad File Descriptor appears

	Am I doing something wrong ?
	Any help will be much appreciated. Thank in advance,

                                              Fabio.
