Description Sandro Bonazzola 2015-03-25 15:48:38 UTC

ovirt-ha-agent and ovirt-ha-broker doesn't handle properly service dependencies.

It should be needed to start only the root service (I guess ovirt-ha-agent), that should depend on the other service.

Once upgraded the %post should restart service if harmless and should be.

Currently it seems that only install dependencies are handled:

 [Install]
 WantedBy=multi-user.target
 Also=ovirt-ha-broker.service

From what I see in the code the agent does depend on the broker.

hosted-engine-ha/initscripts/ovirt-ha-agent.service[3]:
"
Wants=ovirt-ha-broker.service
"

And according to the systemd.unit man page: 

Wants=
This is the recommended way to hook start-up of one unit to the start-up of another unit.


So Wants= create dependencies between services.

After checking with Sandro it seems that the bug was fixed.
