one more thing, which i am sure that most ppl are not aware of. when using thin provisioned disks for vms, hosted on iSCSI SAN Ovirt uses a for me unusual way to do this. Ovirt adds a new LVM LV for a vm, generates a Thin Qcow Image which is written directly raw onto that LV. So for, ok, can be

Hi Elad, thank you very much for clearing things up. Initiator/iface 'a' tries to connect target 'b' and vice versa. As 'a' and 'b' are in completely separate networks this can never work as long as there is no routing between the networks. So it seems the iSCSI-bonding feature is not

Thanks. You're getting an iSCSI connection timeout [1], [2]. It means the host cannot connect to the targets from iface: enp9s0f1 nor iface: enp9s0f0. This causes the host to loose its connection to the storage and also, the connection to the engine becomes inactive. Therefore, the host changes
