Description of problem: When using host-deploy via 'reinstall host' VDSM might get upgraded and break HA services if there are new (kwargs for instance). Also, the same is true if HA services are upgraded and VDSM is not restarted (using old libs). Version-Release number of selected component (if applicable): 3.4+ How reproducible: always Steps to Reproduce: 1. Install a 3.4 HA host for HE 2. Install ovirt 3.5 repo on the host 3. Upgrade the host using Engine's reinstall 4. On the host, perform a yum update ovirt-engine-ha 5. Restart ovirt-ha-agent and ovirt-ha-broker service Actual results: Logs filling up with: 012TypeError: get_all_stats_for_service_type() got an unexpected keyword argument 'storage_dir' Expected results: ovirt-engine-ha is upgraded and restarted from along with VDSM Additional info: This problem gets solved by restating VDSM - along with additional downtime of the host
can be done by adding plugins within the hosted package.
When working on this, please verify upgrade is allowed only in maintenance mode and HE is in local maintenance mode.
