Help KVM IP Conflict and Server Data Changes on BuyVM
I opened this thread not for blaming anyone, just want to get more insight into what happened.
I have server buyvm kvm slice (lux dc) using Ubuntu 16.04.
I always log in using public key and disable root password login.
But recently, when SSH'ing into my server, I got this:
"WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED"
also, it's asked root password.
After open ticket, they explain they have IP conflict, and we agree to replace the IP.
But this is the weird thing when trying to SSH with new IP, it's still asked root password (remember, my old machine using public key). So I suspect this new IP not resolved into my old machine.
Then buyvm staff tries to reset root password so I can log in, but now my OS become Ubuntu 18.04 and there's no my data at all.
Is it a normal thing when IP changed then server data also lost?
Or maybe they have some routing problem so after IP changed, still not resolved into my old machine?
@Francisco maybe you could help..
