Hi guys.
I have VM with hosted engine and a two node setup. When beta came out I was “OH! New shiny
tech! Let’s try it!”. You all know the feeling.
Unfortunately the upgrade process did not go as expected.
I created a backup of my 4.1 installation and started to upgrade the VM. All went well. I
then migrated all the running VMs to my second node put the cluster in global maintenance
mode and updated one of the nodes.
Then I run hosted-engine —upgrade-appliance on the node but it fails:
[ ERROR ] Failed to execute stage 'Environment customization': exceptions must be
old-style classes or derived from BaseException, not str
The log file says:

DUMP - END
I can login to the hosted engine but the nodes are down, the VMs are down and the storage
is not connected.
Can you please advice what to do now?
Is there a way to upgrade my setup?
Should I disconnect my second node, which is also upgraded to 4.2 now and try to install
hosted engine from scratch?
Anything else I can do to save my VMs?
Cheers
Marcin.

oVirt upgrades between versions (major or minor) has always been a bit
difficult for some people, including me. It would be nice if this could
be more extensively tested before release. As people are mostly eager to
upgrade this can be benefitial to dev team to gather even more feedback
from early adopters.

Please provide more details.
You upgraded the engine vm to current 4.2 beta? yum update and engine-setup?
Then you moved a node to local maintenance, and updated it to 4.2
beta, using yum update?
Moving to global maintenance is for upgrading the engine vm, not a host.
Which documents did you follow?
Then I run hosted-engine —upgrade-appliance on the node but it fails:
Where did you find instructions to use this tool?
It's meant only for migrations from 3.6 to 4.0, not general upgrades.

AFAICT a failure at this stage should be harmless - it's before doing
significant changes to the system.
Please share the log, just in case.
I can login to the hosted engine but the nodes are down, the VMs are down and the storage
is not connected.
Are you sure all was fine before you ran this tool?
I do not think your problems are a result of running the tool.
Can you please advice what to do now?
Is there a way to upgrade my setup?
Should I disconnect my second node, which is also upgraded to 4.2 now and try to install
hosted engine from scratch?
Anything else I can do to save my VMs?
Not sure what your exact state is, or what is important to you and what isn't.
Are your VMs up?
Is it important to keep them up?
If not, you can reinstall everything from scratch and import the storage domain.
Otherwise, please provide more details - including relevant logs
(engine, vdsm, etc),
actions you took, etc.
Generally speaking, current 4.2 is not meant for production yet.
It's intended for people that want to see/test the new features etc.
