I've having to rebuild an environment that started back in the early 3.x days. A lot has changed and I'm attempting to use the Ovirt Node based setup to build a new environment, but I can't get through the hosted engine deployment process via the cockpit (I've done command line as well). I've tried static DHCP address and static IPs as well as confirmed I have resolvable host-names. This is a test environment so I can work through any issues in deployment.
When the cockpit is displaying the waiting for host to come up task, the cockpit gets disconnected. It appears to a happen when the bridge network is setup. At that point, the deployment is messed up and I can't return to the cockpit. I've tried this with one or two nic/interfaces and tried every permutation of static and dynamic ip addresses. I've spent a week trying different setups and I've got to be doing something stupid.
Attached is a screen capture of the resulting IP info after my latest try failing. I used two nics, one for the gluster and bridge network and the other for the ovirt cockpit access. I can't access cockpit on either ip address after the failure.
I've attempted this setup as both a single host hyper-converged setup and a three host hyper-converged environment...same issue in both.
Can someone please help me or give me some thoughts on what is wrong?
There are two parts here: 1. Fix it so that you can continue (and so that if it happens to you on production, you know what to do) 2. Fix the code so that it does not happen again. They are not necessarily identical (or even very similar). At the point in time of taking the screen capture: 1. Did the ovirtmgmt bridge get the IP address of the intended nic? Which one? 2. Did you check routing? Default gateway, or perhaps you had/have specific other routes? 3. What nics are in the bridge? Can you check/share output of 'brctl show'? 4. Probably not related, just noting: You have there (currently on eth0 and on ovirtmgmt, perhaps you tried other combinations): 10.1.2.61/16 and 10.1.1.61/16 . It seems like you wanted two different subnets, but are actually using a single one. Perhaps you intended to use 10.1.2.61/24 and 10.1.1.61/24. 5. Can you ping from/to these two addresses from/to some other machine on the network? Your laptop? The storage? 6. If possible, please check/share relevant logs, including (from the host) /var/log/vdsm/* and /var/log/ovirt-hosted-engine-setup/*. Thanks and best regards, -- Didi
