ReadyNAS Ultra 4: Stuck at booting. 97% after add drive and power outage.

Help!

 

Went to add a third drive where the expansion process started, but then lost power.  On boot the ReadyNAS box is now stuck at "Booting ...  97%"

 

Logging on to the box there is a process that is at 99.9% CPU usage called 'md127_raid5'.

 

Not sure what to do. Just give it more time? Maybe it is stil expanding?  The 'activity' led on the front almost looks like it is in a pattern of some sort, but slow.  Probably going to pay the service fee through netgear bu thought I would ask here first.

    You should be able to see what's going on with the array by entering

    # cat /proc/mdstat

    or if you want to monitor it you can use

    # watch cat /proc/mdstat

      Thanks. Looks like it’s stuck. Note the 0% and the minutes remaining. Oh boy......
