UPDATE - I went back to the flash drive to see what files had been mnodified diring attempted upgrade and those included the super.dat file. When I copied the old one from 4.7 over the revised one, everything was back to normal. Now I have to figure out why no web gui is available after the 5.0 upgrade. Suggestions appreciated.
All,
I followed the upgrade instructions for 4.7->5.0rc and after I copied bzimage and bzroot extracted from the zip file, on reboot, no web gui, just the command prompt. So I re-copied the 4.7 bzimage and bzroot files back to the flash drive and rebooted.
This time I was able to launch the web gui but the array was stopped with a bunch of DISK_WRONG errors. I checked in the device list and the correct drives are in the correct slots.
I think this has to do with the model# vs serial # id differences betw. 4.7 and 5.0 but I can't find a fix. I searched on several terms.
Here are the pertinent lines from the syslog:
