Public bug reported: The SRU recently landed for https://bugs.launchpad.net/nova/+bug/1349888 introduced a potential upgrade regression if nova services are not upgraded all at once.
2015-10-14 20:45:00.778 10909 TRACE nova.api.openstack RemoteError: Remote error: UnsupportedVersion Endpoint does not support RPC version 3.35 2015-10-14 20:45:00.778 10909 TRACE nova.api.openstack [u'Traceback (most recent call last):\n', u' File "/usr/lib/python2.7/dist-packages/oslo/messaging/rpc/dispatcher.py", line 133, in _dispatch_and_reply\n incoming.message))\n', u' File "/usr/lib/python2.7/dist-packages/oslo/messaging/rpc/dispatcher.py", line 185, in _dispatch\n raise UnsupportedVersion(version)\n', u'UnsupportedVersion: Endpoint does not support RPC version 3.35\n']. Basically, if nova-compute services are updated after nova-api services you will hit this issue if you perform volume operations. A simple solution, if possible, is to upgrade nova-compute services so that they are all in sync but I still want to remove the possibility for regression while keeping the fix from 1349888. I will propose an SRU shortly to resolve this. ** Affects: nova (Ubuntu) Importance: High Assignee: Edward Hope-Morley (hopem) Status: In Progress ** Changed in: nova (Ubuntu) Status: New => In Progress ** Changed in: nova (Ubuntu) Importance: Undecided => High ** Changed in: nova (Ubuntu) Assignee: (unassigned) => Edward Hope-Morley (hopem) -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to nova in Ubuntu. https://bugs.launchpad.net/bugs/1506257 Title: rpcapi version mismatch possible on upgrade To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nova/+bug/1506257/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
