Hello, everyone! I need specialist help, because I'm already desperate. My company has four hosts that are connected to the vault. Each host has its own IP to access the storage, which means host 1 has an ip 10.42.0.10 and 10.42.1.10 -> host 2 has an ip 10.42.0.20 and 10.42.0.20 respectively. Host 1 cannot ping the address 10.42.0.20. Hardware I tried to explain in more detail. Host 1 has ovirt node 4.3.9 installed and hosted-engine deployed. When trying to add host 2 to a cluster it is installed, but not activated. There is an error in ovirt manager - "Host host2 cannot access the Storage Domain(s) <UNKNOWN>" and host 2 goes to "Not operational" status. On host 2, it writes "connect to 10.42.1.10:3260 failed (No route to host)" in the logs and repeats indefinitely. I manually connected host 2 to the storage using iscsiadm to ip 10.42.0.20. But the error is not missing(. At the same time, when the host tries to activate it, I can run virtual machines on it until the host shows an error message. VMs that have been run on host 2 continue to run even when the host has "Not operational" status. I assume that when adding host 2 to a cluster, ovirt tries to connect it to the same repository host 1 is connected to from ip 10.42.1.10. There may be a way to get ovirt to connect to another ip address instead of the ip domain address for the first host. I'm attaching logs: ----> /var/log/ovirt-engine/engine.log 2020-03-31 09:13:03,866+03 WARN [org.ovirt.engine.core.dal.dbbroker.auditloghan dling.AuditLogDirector] (EE-ManagedThreadFactory-engineScheduled-Thread-90) [7fa128f4] EVENT_ID: VDS_SET_NONOPERATIONAL_DOMAIN(522), Host host2.school34.local c annot access the Storage Domain(s) <UNKNOWN> attached to the Data Center DataCenter.
