Re: [ovirt-users] Hosted-Engine Agent broken

Hi,

make sure you have at least ovirt-hosted-engine-ha-2.2.1 and the
service was properly restarted.

The situation you are describing can happen when you run older hosted
engine agent with 4.2 ovirt-engine.

It was tracked as: https://bugzilla.redhat.com/1518887

Best regards

Martin Sivak

[ovirt-users] Hosted-Engine Agent broken

[Sven Achtelik]

Hi All,

after upgrading my engine to 4.2 and upgrading my hosts to the latest  versions 
the HA for the hosted engine is not working anymore. The Agent fails with the 
following errors. Did I miss anything while upgrading ? The Engine is still 
running - what would be the correct approach to get the HA services up and 
running ?

recent call last):

If anyone could give a hint on where to look at would be very helpful.

Thank you,
