CentOS

I've got Centos 6.8 running on an EVGA board with the raid enabled (raid 1). I've got a strange issue in the boot log file I can't seem to figure out. Everything boots up, and the server is working just fine. However, this is listed in the boot.log

Run MD devices: mdadm: array /dev/md/Volume0 now has 2 devices (0 new)
[60G[[0;31mFAILED[0;39m]

Any ideas for a newbie?
