Had a rough time last weekend, figured I’d discuss it here and see if anybody has insights …
I had setup a significant test in my office that went without a hitch and so I unleashed the migration tool on my little (29 nodes) production network. After five or ten minutes of nothing notable happening in cnMaestro cloud version I clicked on the new controller and it started showing the sites and asked for the POP unit’s serial # just as had occurred in my practice.
The rest of nodes did not show as red or green for offline/online but rather just in grey or black and indicated they required the serial #'s for each, I dug into the backup.tar.gz to look for them but they were nowhere obvious.
Panic setting in I tried to load the backup, cnmaestro was having none of that, tried restarting the e2e controller that had run as onboard for a year, no joy, devices being claimed by another controller says no way jose.
Fine, I figure its not that many nodes I’ll just go through the tedium of retrieving ech node’s serial # and be back in action …
No such luck, wireless links come up from the pop node but next nodes remain offline, I assume this is an IPv6 route/gateway issue but after a brief struggle trying to fake my through this I felt I’d had enough and just wanted network back the way it was before the clients on it got their torches and pitchforks together …
I wiped all the nodes out of the external e2e and factory reset the POP, loaded the backup and too many hours later was back where I started before I touched anything.
Anybody else seen mayhem like this ? Got any pointers/suggestions ?
