Due to networking and DNS issues. our engine was offlined (it is<br>
physical machine currently, will be converting it to a VM in the<br>
future when time allows). When service was restored, I noticed that<br>
all the VMs were listed as being in an unknown state on one host. The<br>
VMs were fine, but the engine could not ascertain their status as the<br>
host itself was in an unknown state. vdsm was reporting errors and was<br>
not running on the engine (or at least was in status 'failed' in<br>
systemd). I tried starting vdsmd on the engine but it would not start.<br></blockquote></div></div></div><div dir="auto"><br></div><div dir="auto">VDSM should not be running on the engine. </div><div dir="auto"><br></div><div dir="auto"><div class="gmail_extra"><div class="gmail_quote"><blockquote class="quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
I decided to try to restart vdsmd on the host and that did allow the<br>
state of the VMs to be discovered, and the engine listed the host as<br>
up again. However, there are still errors with vdsmd on both the host<br>
and the engine, and the engine cannot start vdsmd. I guess it is able<br>
to monitor the hosts in a limited way as it says they are both up.<br>
There are communication errors between one of the hosts and the<br>
engine: the host is refusing connections by the look of it<br></blockquote></div></div></div><div dir="auto"><br></div><div dir="auto">Is iptables / firewalld set up correctly? </div><div dir="auto">Y. </div><div dir="auto"><br></div><div dir="auto"><div class="gmail_extra"><div class="gmail_quote"><blockquote class="quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
