Except that Gary is using a mirror and ccd(4) claims to provide either
concatenated or interleaved disks, not mirroring:
"A ccd may be either serially concatenated or interleaved."
and as such provides no tolerance for disk failures:
"WARNINGS
If just one (or more) of the disks in a ccd fails, the entire file
system will be lost."
I use RAIDframe and haven't used ccd, so I'm just going by what the man
page says...
