Hello csk611 ,
At this point, you can try any of the troubleshooting steps that N. Scott Pearson, posted but usually when a volume has failed, there is no way to recover it.
When you can rebuild the raid, you will see the status as degraded but once it fails, it fails.
I hope that you can have a back up of your information and you can try to set the disks as non-raid and create the raid again.
