Hi All, I was running Openstack Multinode setup with Folsom release. I upgraded it to Grizzly. Due to some reasons I had to format the Controller Node. Now I have a newly deployed Grizzly controller node and upgraded Compute and Network nodes. I am facing an issue with this setup which is described below:-
If I check the *INSTANCES* table in *NOVA* database of Folsom release, I could see that it contains a column "*server_name*" which is now *not present* in the Grizzly release. Is there a specific reason why this column is removed from the database? I am facing an issue that the upgraded Compute node's code is looking for server_name column which is not present in my Nova database since the node is fresh installed. Is there a way to completely remove the installed nova-packages for Folsom release from the node and install the latest Grizzly ones without format? Most of the times I try apt-get remove <package-name>, I end up messing up with the setup and libraries. Your feedback for this issue would be really helpful. Thanks and Regards Rahul Sharma
