[ovirt-users] ERROR: Malformed metadata for host 3

Hi, we have a Hyperconverged oVirt Cluster with three machines. All three are running GlusterFS (Replica 3), and on two of them we are running the VMs (because they have better hardware). Now we wanted to add a new oVirt host. Due to some network related errors, adding this host was unsuccessful, so we removed it from GUI and also via "hosted-engine --clean-metadata --host-id=3 --force-clean" (as it was still listed using "hosted-engine --vm-status" after removal from the GUI). Inside the GUI and with "hosted-engine --vm-status", everything looks fine now, the third oVirt host is gone, and there are no problems at all. But in the /var/log/ovirt-hosted-engine-ha/agent.log, we now get every 15 minutes a "MainThread::ERROR::2018-09-05 10:20:17,190::hosted_engine::793::ovirt_hosted_engine_ha.agent.hosted_engine.HostedEngine::(process_remote_metadata) Malformed metadata for host 3: received 0 of 512 expected bytes", on both of the remaining oVirt hosts. Can someone explain what is wrong? oVirt 4.2.2.6-1.el7.centos Thank you Markus
