I have finished the upgrade to 3.6.
I received a lot (every 3 seconds ) of the following messages in the logs after upgrading the hosts:
vdsm jsonrpc.JsonRpcServer ERROR Internal server error#012Traceback (most recent call last):#012 File "/usr/lib/python2.6/site-packages/yajsonrpc/__init__.py", line 501, in _serveRequest#012 res = method(**params)#012 File "/usr/share/vdsm/rpc/Bridge.py", line 291, in _dynamicMethod#012 return self._fixupRet(className, methodName, ret)#012 File "/usr/share/vdsm/rpc/Bridge.py", line 235, in _fixupRet#012 self._typeFixup('return', retType, result)#012 File "/usr/share/vdsm/rpc/Bridge.py", line 215, in _typeFixup#012 if k in item:#012TypeError: argument of type 'NoneType' is not iterable
I restarted ovirt-ha-agent ovirt-ha-broker and vdsmd.
After I rebooted all hosts ( migrating VMS from one to another ) the message finally disappeared.
Then I tried to set compatibility Version to 3.6, but without luck. I have put hosted engine back in global maintenance, but I can't find out why it fails. The message says "Error while executing action: Cannot change Cluster Compatibility Version to higher version when there are active Hosts with lower version.
-Please move Hosts with lower version to maintenance first."
I have installed ovirt-release36 on hosted engine and hosts.
I have updated hosted engine with engine-setup.
I ran yum update on all hosts.
What do I need to do to set compatibility version to 3.6?
And how can I enable repository for hosted engine? ( through WEB UI change is not saved ).
Met vriendelijke groeten,Paul Groeneweg
