(e.g. a 4.5gb IDE and a 2gb SCSI?) Aaargh. That's what comes of answering messages before reading them. For some reason I was thinking of mirroring. You *should* be able to configure disks this way if you don't interleave. I haven't tried it, but I have looked through the source code. It looks as if you can even specify interleave > 1 with unequal partions, but in this case it truncates all the partitions to the size of the smallest, definitely not what you want. vinum can do partial mirroring and true concatenation of unequal size partitions. It can't interleave unequal sized partitions. I consider it a bug, not a feature, than CCD should allow this. > Or whether you can CCD' an allready CCD'd array? I still think this is a bad idea.
