Hello,<br>
<br>
We've just deployed the ovirt-4.1 hosted_engine and I have noticed 2 things that it would be great if people can comment on:<br>
<br>
1) It seems that iptables is a hard requirement:<br>
<br>
> iptables was detected on your computer, do you wish setup to configure it? (Yes, No)[Yes]: no<br>
<br>
[ INFO ] Connecting to the Engine<br>
[ INFO ] Waiting for the host to become operational in the engine. This may take several minutes...<br>
<font color="#ff0000">[ ERROR ] The VDSM host was found in a failed state. Please check engine and bootstrap installation logs.</font><br>
<font color="#ff0000">[ ERROR ] Unable to add example-host.tradingscreen.com to the manager</font><br>
[ INFO ] Saving hosted-engine configuration on the shared storage domain<br>
[ INFO ] Shutting down the engine VM<br>
<br>
Here is a bug report from 3.5.0 with this exact error:<br>
<br>
<b><a href="https://bugzilla.redhat.com/show_bug.cgi?id=1167074">Bug 1167074</a></b> - [hosted-engine] Deployment fails with "The VDSM host was found in a failed state. Please check engine and bootstrap installation logs." <br>
<br>
Previously, iptables-services was not a required package during hosted-engine deployment, so hosted-engine was unable to configure iptables. Now, iptables-services is <br>
required, so hosted-engine can configure iptables correctly.<br>
<br>
2) We have to add new storage to the default domain before the hosted_engine storage domain is imported. So is this happening because of the iptables issue in # 1 above ?
<br>
Or is adding this new storage to the default domain also a hard requirement ? Ideally we'd like the hosted_storage to be the Data Master and not have to create stub storage for this.<br>
<br>
Here is a bug report from 3.6.1 with this exact error:<br>
<br>
<b><a href="https://bugzilla.redhat.com/show_bug.cgi?id=1293928">Bug 1293928</a></b>
<font color="#000000">Cause: importing the nfs domain could interleave with the engine restart as a result of installation.
</font><br>
<br>
<font color="#000000">Consequence: the hosted engine domain won't be imported or activated on the engine setup, and the engine vm wouldn't be imported and displayed in the webadmin or REST. </font><br>
<br>
<font color="#000000">Fix: Exclusively lock the import attempt so interleaving of 2 imports is impossible and prevent starting the import if there is no DATA domain and an ACTIVE DC. </font><br>
<font color="#000000">Note: this means that in order to see the engine VM a user must first import a DATA domain and activate the DC. </font><br>
<br>
<font color="#000000">Result: the hosted engine domain is imported and the hosted engine VM.</font><br>
<br>
Thanks,<br>
Joe.<br>
