I have finished the upgrade to 3.6.
Can you describe how you've performed the upgrade? Did you upgrade Engine first and then all the hosts (it is highly recommended to upgrade host one at a time, and move each to maintenance mode before doing so)? When did the troubling log appeared?
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.
Can you share your vdsm.log of that time? I wish to understand what method has failed.
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."
Can you iterate over your hosts to find which is the culprit? Then you can move it to maintenance.
As far as I understood all the hosts were el6 and so no one got really upgraded.
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 ).
