Change subject: hosted-engine: prevent a race cond. between ha-agent and vdsm ...................................................................... hosted-engine: prevent a race cond. between ha-agent and vdsm Without this, host-deploy will first start ovirt-ha-agent that will bring up vdsm due to systemd dependencies but, just after that, host-deploy will (re)start vdsm. If ovirt-ha-agent is not quick enough, vdsm will be restarted in the middle of connectStorageServer that will not complete, because vdsm was stopped and does not continue such operations upon restart. On the other side, the timeout waiting for connectStorageServer to be completed is pretty long (900 seconds) so ovirt-ha-agent will take a lot of time to realize the issue. In the mean time, ovirt-ha-broker will fail accessing the shared storage and vdsm get the error and reports back a bad status to the engine and so adding the host from the webui could fail if ovirt-ha-agent is not fast enough. Reversing the start order of vdsm and ovirt-ha-agent will prevent this since ovirt-ha-agnet has Wants=vdsmd.service and After=vdsmd.service and both are met.
