 * 1 . I've been attempting to get disk mirroring working 
 * following the directions below. I can make it to the point
 * where I create the 1-disk ccd, however, I have troubles 
 * disklabeling it. When I attempt "disklabel -w -r ccd0 auto"
 * I get back "disklabel: open(): No such file or directory".
 * The man pages for disklabel mention that there may be
 * problems with this, but do not give any solutions. Does 
 * anyone know how to make this work so I can label ccd0?
 * 
 * BTW, I tried going ahead anyway and editiing the disklabel
 * using "disklabel -e ccd", but this created errors if I just 
 * tried to label the e & f partitions. The man pages stated that
 * some drivers only would work with "a" paritions for unlabeled
 * disks and I tried that as well without success.

Aw shucks.  I haven't tried the "auto" myself, didn't know that
doesn't work with ccd.

Yes, it seems like you can't edit the ccd disklabel (with disklabel
-e) without writing one first.  (The output you get by just calling
disklabel on ccd0 is a "fake" one and you can't edit that.)

Just save the output of "disklabel ccd0" in a file, write *some* label 
(e.g., "disklabel -wr ccd0 fuji513", look at /etc/disktab for
entries), and then use "disklabel -e ccd0" and save the result back.
You can then modify it.
