I am currently experimenting with ccd(4) and although it appears to work, I am uncomfortable with one point.

I have configured 2 partitions as a JBOD (interleave 0). However, the first of these partitions is partition 'a' of one disk. So the first effect I had was that ccd0 appeared to have the same disklabel as the first disk.

I read through the mailing list archives and found a thread explaining that the disklabel is stored around the beginning of partition 'a' and that one should allocate a small partition 'a' which should not be made part of the JBOD.

What I am uncomfortable with is that

1) this does not appear to be documented in the man pages anywhere

2) that the size and position of the disklabel of partition 'a' is not clearly stated anywhere so that I can be certain that it doesn't get overwritten and that I am not wasting too much space.

Can anybody please shed some light on this?

Regards,
