I have two 850M Quantium SCSI (TRB850S) and want to use ccd to become
one big disk. I had tried many many times and I give up. I would like
anyone to tell me what is the proper steps to do so.  I found that when
I disklabel sd1 sd2 and then ccd0 (with double the size of total sectors
and cylinders). I got the disklabel of sd1 and ccd0 are the same and sd2
is different. I can newfs ccd0 with correct size and write and read from
the ccd0. Everything seems ok.  when I reboot system, ccd0 report failed
because of sd2 didn't have the label. When I made the size of sectors
and cylinder of sd1, sd2 and ccd0 are the same, I only got the size of
one disk capacity. Can anyone help ? thanks.

e.g.  disk   cylinder  sectors
      ----   --------  -------
       sd1       1000    50000
       sd2       1000    50000
      ccd0       2000   100000

after ccdconfig, cyl and sect of sd1 become 2000 and 100000
respectively. It is very strange. mye kernel is (960720)
