But I just created the Cluster and I can see the nodes in the list so I dont get it why I cant migrate the VM and its saying key is not the same am I doing something wrong.
 
I fix that by running pvecm updatecerts - now I got this error

Its fixed - I have uncheck shared storage and everything is working. but do I need a shared storage for HA ?
 
I installed today and recieved the same message during a test migration of a vm.

How do I update these keys to the correct ones?
 
I moved the old known_hosts file as follows,

mv /root/.ssh/known_hosts /root/.ssh/known_hosts.not

Then I logged in to the second node from the offending node that gave the error again as root. After confirming the new key during the ssh login, it's working fine now.
