As far as I know, CCD (concatenated disk) can not do mirroring, so your RAID-1
disk won't be created using CCD.

According to the man page, descriptions of the various fs_type's are in
/usr/include/sys/disklabel.h, and indeed:
...
#define FS_RAID 15 /* RAIDFrame drive */
...
static const char *fstypenames[] = {
...
"raid",
...
};
So, apparently your disk contains a "RAIDFrame drive". I never heard of that
before, but apparently it's something that's part of NetBSD:
http://www.netbsd.org/docs/guide/en/chap-rf.html
So my guess is that the NAS device contained NetBSD instead of FreeBSD.
