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,
