OK, another problem :(
I was having the same problem with my second oVirt host that I had
with my first one, where when I ran “hosted-engine —deploy” on it,
after it completed successfully, then I was experiencing a ~50sec
lag when SSH’ing into the node…
vpnp71:~ will$ time ssh root@ovirt-node-02 uptime
19:36:06 up 4 days, 8:31, 0 users, load average: 0.68, 0.70, 0.67
real 0m50.540s
user 0m0.025s
sys 0m0.008s
So, in the oVirt web admin console, I put the "ovirt-node-02” node
into Maintenance mode, then SSH’d to the server and rebooted it.
Sure enough, after the server came back up, SSH was fine (no
delay), which again was the same experience I had had with the
first oVirt host. So, I went back to the web console, and choose
the “Confirm host has been rebooted” option, which I thought would
be the right action to take after a reboot. The system opened a
dialog box with a spinner, which never stopped spinning… So
finally, I closed the dialog box with the upper right (X) symbol,
and then for this same host choose “Activate” from the menu. It
was then I noticed I had recieved a state transition email
notifying me that "EngineUp-EngineUpBadHealth” and sure enough,
the web UI was then unresponsive. I checked on the first oVirt
host, the VM with the name “HostedEngine” is still running, but
obviously isn’t working…
So, looks like I need to restart the HostedEngine VM or take
whatever action is needed to return oVirt to operation… Hate to
keep asking this question, but what’s the correct action at this
point?
ovirt-ha-agent should always restart it for you after a few minutes
but the point is that the network configuration seams to be not that
stable.
I know from another thread that you are trying to deploy hosted-engine
over GlusterFS in an hyperconverged way and this, as I said, is
currently not supported.
I think that it can also requires some specific configuration on
network side.
For hyperconverged gluster+engine , it should work without any specific
configuration on network side. However if the network is flaky, it is
possible that there are errors with gluster volume access. Could you
provide the ovirt-ha-agent logs as well as gluster mount logs?
Adding Sahina and Dan here.
Thanks, again,
Will
