Same thing happened to me. I managed to find some help, and the
followinging worked for me. I only had the /dev/md0 device defined.
ckraid --force-check --fix /dev/md0
Then, I was told to mount it, and I did, but it may not be necessary.
Then I rebooted and everything went fine.
I noticed that the --force-check option was not in the man page, but
did show up when you do "ckraid --help". By the way, I also made
a backup before I did this.
