I'm trying to create a raid set but after hitting the end of 
initializing a raid5
stripe the following is displayed on the console:

raid0: node (Rod) returned fail, rolling backward
raid0: IO Error.  Marking /dev/da2s1e as failed.
raid0: node (Rod) returned fail, rolling backward
raid0: IO Error.  Marking /dev/da1s1e as failed.
