SCSI-2 drives, on an adaptec 2940 controller.
ccdconfig ccd0 128 6 /dev/sd0f /dev/sd2f

>Description:

In testing ccd for use as a disk mirroring facility, tests determined
that disk failure could cause a filesystem inconsistency.  For testing
purposes, I set up two identical disk slices, and mirrored them with
ccd.  Whne I turned off the external drive, copies to the ccd device
failed as expected, but I was able to unlink existing files.  When I
brought the external drive back on line, fsck found the unlinked
files, and dutifully placed them in lost+found.  CCD did not report
the write failure to syslog.

>How-To-Repeat:

	See above.
