Ready NAS 312 - Web Admin Console is not accessible after firmware upgrade

NAS 312 has been running great for the past year or so, but needed to login to update some accounts recently.  While in there I noticed the web console was bit sluggish and also noticed that there was a firmware upgrade.  The screens were taking so long to load that I gave up trying to add the user account and opted to perform the firmware upgrade.  I was on version 6.9.4 and was moving to the latest which I think is 6.10.3.  I left it running over night, only to find the NAS device in an usable state the next morning.  Blue light was flashing, no HD green lights. I decided to power it down and power it back up.  After rebooting and waiting a long time (10 mins), the blue light finally stated solid and the 2 green HDD lights were on.  However the Web Admin console is non responsive and the shares are not accessible.  I can hear the NAS doing something as I hear the drives moving (sounds like a defrag or something), however it is not accessible.  In my router I can see it was assigned an IP address and I see the NIC card lights flashing.  I have let it sit this way for about day to see if its some restoration or cleanup that it needed to perform in hopes that it comes back online.  During the long boot up (i.e the 10 min wait), I was able to use the Raidar tool and it connected and I could see the status of upgrading (upon a second reboot) the status later changed to "Starting Up".  However now that all the lights are correct the Raidar tool will no longer connect.  Unfortunately, I didn't do a backup of the data before starting all this, so looking for help to see how I can get the NAS back online and more importantly without losing any data.  I have not tried anything aggressive like pulling drives out for fear of losing data. 

Should I keep waiting?  Is there any way of seeing what the NAS is doing?  Any help or ideas would be appreciated?

Thanks
