In continuation of "raidctl -P all in /etc/rc" theme. Please, can you explain what difference between RAID mirroring and CCD mirroring?
I see that RAID have reconstruction option, and trace parity condition. In the other side, it need to "raidctl -P all" and wait for it before start system. I read ccd(4), ccdconfig(4), but they are not describe what I want to know. And, briefly, what difference between RAID and CCD in such fields like "performance", "what to do after one disk fail", and "what will be when one disk fail while system running". -- engineer
